Excavation is most commonly and best known for a
technique within the science of archaeology. The
individual types of excavation are known simply
as digs to those who participate, with this being
an over literal description of the process. An
excavation concerns itself with a specific
archaeological site or connected series of sites,
and may be carried on over a number of years, since
the work is normally seasonal.
Within the industry of excavation, many more
techniques may be utilized, with each dig having
its own particular features that may necessitate
differences of approach. Resources and other
practical issues don't allow archaeologists to carry
out excavations whenever and wherever they choose,
as many known sites have been deliberately left
alone and non excavated.
Initially, excavation involves the removal of any
topsoil that is uncovered by machine. What is
dug up may be examined by a metal detector for stray
finds but unless the excavation site has remained
untouched for a long period of time, there is a
small layer of modern material on the surface that
is of limited archaeological interest.
In rural areas, any type of archaeological features
should be visible beneath the surface. With
urban areas, they may be thick layers of human
deposits and only the uppermost will be visible to
the naked eye. With either case, the first task
is drawing a scaled site plan that will show the
edges of the excavation.
This plan can be composed using tape measures, or
as it is more common these days, an electronic
total station. A grid is normally set up, to
divide the site.
Excavation is also useful for digging out houses
and trenches. When clearing dirt out for roads
or sub divisions, excavation is what takes care of
things. Even though there are a few means, the
term excavation is used anytime that the earth or
dirt is disturbed.
Heavy machinery is also very common with excavation,
such as excavators or backhoes. Excavating crews
run the equipment and dig up soil and rocks for
whatever the purpose may be. Excavators are the
most used machinery, as they can move a lot of dirt
in a little bit of time.
Anytime you are taking part in excavation, you should
always use common sense and be safe. If you plan
to get down into a hole or trench, you should always
use a trench box. Even though the hole may not
be that deep, excavation sites can always cave in
and at that point - things are very dangerous and
possibly even deadly.
For digging up rare artifacts or putting in houses
or roads, excavation is something that has been around
for years and years. There is a lot to learn with
excavation, as you'll need to know how to run
machinery, shoot grade, and how to properly dig
holes and trenches so they won't cave in.

different Types Of Backhoe Loaders
Caterpillar
Caterpillar hit a dial of power and performance with
its top of the line 446 backhoe loader when it first
introduced the D series version of the machine. The
102 HP machine also features a new operator station
and offers optional joystick controls. The dig
forces on the bucket have increased 10% on the
backhoe.
Bobcat
Bobcat gave its compact backhoe loaders a power
boost when the company introduced the second generation
B series to the lineup. The 31.5 HP B100 received
a 45% increase in backhoe bucket breakout force
and a 27% jump in the breakout force of the dipper.
The 46 HP B300 received a 44% increase in dipper
breakout force and a 21% boost in the breakout
force of the bucket. The three model line also
includes the B250, which is a 31.5 HP sideshift
unit. Similar to the larger B300, the B250 also
features all wheel steering and four wheel drive.
New Holland
Each one of the four models of backhoe loaders in
the New Holland lineup use the new 4.5 liter
turbocharged Tier 2 engine. This new engine and
a number of other upgrades were the basis for the
B series machines, which offer low effort pilot
controls which will give you a choice between
excavator or loader style patterns.
Case
Case added quite a bit to its M series backhoe
loaders, by switching to family 3 engines to meet
Tier 2 emission standards. The new machines
of the M series have quieter, larger displacement
engines for better lugging capacity. They also
have increased torque rise for faster cycles
of loader and backhoe operations.
With 500 hour intervals of oil changes and easy
to access transmission mounted hydraulic pumps,
the M series is surely a force to be reckoned
with in the world of backhoes.
Ingersoll-Rand
The newest compact backhoe loader from this
company can reach digging depths of up to 12
feet with its backhoe. Working as a loader, the
BL-580 has an operating capacity of 3,406 pounds
with a breakout force of 9,370 pounds.
Both the loader and backhoe are equipped with
standard auxiliary hydraulics with a two way
flow to accommodate a variety of attachments,
which includes booms, breakers, augers, and
even compactors. Other nifty features include
hydrostatic four wheel drive for power and traction,
and all wheel steering for a tight radius.
Komatsu
Komatsu announced that the optional excavator
style joystick controls would be offered on its
five model lineup of backhoes. The lineup has
also been upgraded with increased hydraulic speed,
stronger components, and Tier 2 engines. The
entire Komatsu line consists of the 87 HP WB140
series, and teh 94 HP WB150 series.
The standard model found with each series features
a four speed mechanical transmission complete with
a torque converter. The fifth model from Komatsu
is the WB150, with offers an all star wheel design
with a powershift transmission and anti theft
prevention system.
John Deere
The 410H is the hallmark of John Deere, offering
92 HP. The 410H also offers the total machine
control system, which integrates control for the
engine, transmission, hydraulics, and brakes so
that the system can respond in an efficient way
to the many different job demands.
Terex
Since acquiring the Fermec line, Terex has marketed
a full and impressive line of backhoes. The
models include the 92 HP TX760B and the 100 HP
TX860B. At 100 HP as well are the 860SX, 860 Elite,
and the 970 Elite. Both the 760 and 860 models
feature four speed shuttle gearboxes and travel
speeds of up to 25.8 miles per hour.

Cranes
A crane is a tower or derrick that is equipped with
cables and pulleys that are used to lift and lower
material. They are commonly used in the construction
industry and in the manufacturing of heavy equipment.
Cranes for construction are normally temporary
structures, either fixed to the ground or mounted
on a purpose built vehicle.
They can either be controlled from an operator in
a cab that travels along with the crane, by a push
button pendant control station, or by radio type
controls. The crane operator is ultimately responsible
for the safety of the crews and the crane.
Medieval cranes
Cranes of the Middle Ages were used to build the
cathedrals of Europe. The crane was fixed on top
of a wall as it was being constructed and was
powered by men that ran inside of two large wheels
on each side. Cranes were also used in medieval ports
and in shipyards.
Mobile cranes
The most basic type of crane consists of a steel
truss or telescopic boom mounted on a mobile platform,
which could be a rail, wheeled, or even on a cat
truck. The boom is hinged at the bottom and can
be either raised or lowered by cables or hydraulic
cylinders.
Telescopic crane
This type of crane offers a boom that consists of
a number of tubes fitted one inside of the other.
A hydraulic mechanism extends or retracts the
tubes to increase or decrease the length of the
boom.
Tower crane
The tower crane is a modern form of a balance
crane. When fixed to the ground, tower cranes
will often give the best combination of height and
lifting capacity and are also used when constructing
tall buildings.
Truck mounted crane
Cranes mounted on a rubber tire truck will provide
great mobility. Outriggers that extend vertically
or horizontally are used to level and stabilize
the crane during hoisting.
Rough terrain crane
A crane that is mounted on an undercarriage with
four rubber tires, designed for operations off
road. The outriggers extend vertically and
horizontally to level and stabilize the crane when
hoisting. These types of cranes are single engine
machines where the same engine is used for powering
the undercarriage as it is for powering the
crane. In these types of cranes, the engine is
normally mounted in the undercarriage rather than
in the upper portion.
Loader crane
A loader crane is a hydraulically powered articulated
arm fitted to a trailer, used to load equipment
onto a trailer. The numerous sections can be
folded into a small space when the crane isn't in
use.
Overhead crane
Also refered to as a suspended crane, this type
is normally used in a factory, with some of them
being able to lift very heavy loads. The hoist is
set on a trolley which will move in one direction
along one or two beams, which move at angles to
that direction along elevated or ground level
tracks, often mounted along the side of an assembly
area.
In the excavation world, cranes are used to move
equipment or machinery. Cranes can quickly and
easily move machinery into trenches or down steep
hills, or even pipe. There are many types of
cranes available, serving everything from
excavation to road work.
Cranes are also beneficial to building bridges or
construction. For many years, cranes have proven
to be an asset to the industry of construction
and excavating. Crane operators make really good
money, no matter what type of crane they are
operating.

Comparing Trenchers To Compact Excavators
Both of these machines are affordable, popular,
highly productive, and they both have helped lay a
lot of cable and pipe in the ground. While they
both can do the work, there are differences as
to how they perform when stacked up against each
other in residential utility installations.
Size and price
The average dig depth for utility installations in
residential applications is between 40 and 48
inches. The basic trencher that digs to the above
depth will boast a 20 - 30 horsepower engine and
cost around 40,000 dollars.
The most popular type of compact excavator is the
2.5 metric ton size class, and it uses a 30 HP
engine and costs around the same price. The
biggest difference in the two surfaces when you
need the trencher to dig deeper. The 2.5 metric
ton excavator has no trouble at all digging to 8
feet or more, although a trencher that can dig
that deep will require an engine with around 100
horsepower and cost upwards of 90,000 dollars!
Life costs
Not counting the bucket teeth and the replacement
of the rubber tracks at 2,000 hours, fuel and
routine maintenance are your only daily costs
with a compact excavator. The digging chain, teeth,
and sprockets on the trenchers are considered
wear items and need to be replaced often. Even
with the high consumable costs of trenchers, the
differences will tend to even out when productivity
is taken into effect.
Productivity
For straight line trenching at an average depth,
trenchers will flat out lead compact excavators.
Under reasonable conditions, a trencher can work
three to four times faster than that of a compact
excavator. Another area where trenchers really
excel is wooded areas, where tree roots and logs
can make for slow and sloppy digging when using a
bucket.
Versatility
When it comes down to it, compact excavators can
do a lot of things that trenchers can't, especially
when they have attachments on hand. If you are
digging with a compact excavator, you can't go
anywhere near as fast as you can with a good quality
trencher.
Keep in mind that a trencher isn't a single minded
machine either. Most styles of trenchers can be
outfitted with a backhoe attachment that attaches
to the front end. Whenever concrete, rocks, or
asphalt stands in the way, the boom and chain can
be replaced with rock teeth and a wheel. In soft
soils, you can set up a trencher with a plow
attachment and plow in cables faster than using
any other available method.
When it comes down to choosing, keep in mind that
it all depends on your needs. There are some
cases where the compact excavator is best to
choose, while there will also be jobs in which
the trencher is going to do the best work.

anywhere near as fast as you can with a good quality
trencher.
Keep in mind that a trencher isn't a single minded
machine either. Most styles of trenchers can be
outfitted with a backhoe attachment that attaches
to the front end. Whenever concrete, rocks, or
asphalt stands in the way, the boom and chain can
be replaced with rock teeth and a wheel. In soft
soils, you can set up a trencher with a plow
attachment and plow in cables faster than using
any other available method.
When it comes down to choosing, keep in mind that
it all depends on your needs. There are some
cases where the compact excavator is best to
choose, while there will also be jobs in which
the trencher is going to do the best work.
Compact Excavator
The compact hydraulic excavator can be a tracked or
wheeled vehicle with an approximate operating weight
of 13,300 pounds. Normally, it includes a standard
backfill blade and features an independent boom
swing. The compact hydraulic excavator is also
known as a mini excavator.
A compact hydraulic excavator is different from other
types of heavy machinery in the sense that all
movement and functions of the machine are accomplished
through the transfer of hydraulic fluid. The work
group and blade are activated by hydraulic fluid
acting upon hydraulic cylinders. The rotation and
travel functions are also activated by hydraulic
fluid powering hydraulic motors.
Most types of compact hydraulic excavators have
three assemblies - house, undercarriage, and the
work group.
House
The house structure contains the compartment for
the operator, engine compartment, hydraulic pump
and also the distribution components. The house
structure is attached to the top of the undercarriage
via swing bearing. Along with the work group, the
house is able to rotate upon the undercarriage
without limit due to a hydraulic distribution valve
that supplies oil to the undercarriage components.
undercarriage
The undercarriage of compact excavators consists of
rubber or steel tracks, drive sprockets, rollers,
idlers, and associated components and structures.
The undercarriage is also home to the house
structure and the work group.
Work group
The work group consists of the boom, dipper or
arm, and attachment. It is connected to the front
of the house structure via a swinging frame that
allows the work group to be hydraulically pivoted
left or right in order to achieve offset digging
for trenching parallel with the tracks.
Independent boom swing
The purpose of the boom swing is for offset
digging around obstacles or along foundations,
walls, and forms. Another use is for cycling in
areas that are too narrow for cab rotation. Another
major advantage of the compact excavator is the
independent boom swing.
Backfill blade
The backfill blade on compact excavators are used
for grading, leveling, backfilling, trenching,
and general dozer work. The blade can also be
used to increase the dumping height and digging
depth depending on it's position in relation to
the workgroup.
The most common place you'll find compact excavators
is in residential dwellings. When digging phone
lines or other things, these pieces of equipment
are very common for getting between houses. Due
to their small size, they can fit almost anywhere.
Over the years, the capabilities for compact
excavators have expanded far beyond the tasks of
excavation. With hydraulic powered attachments
such as breakers, clamps, compactors and augers,
the compact excavator is used with many other
applications and serves as an effective attachment
tool as well. Serving many purposes, the compact
excavator is a great addition to any job that
requires the use of machinery.

Caterpillar Equipment
Caterpillar Incorporated, also known as CAT is a
United States based corporation that is based in
Peoria, Illinois. The company commonly known as CAT
is known around the world as the largest manufacturer
of construction and mining equipment, diesel and
natural gas engines, and industrial gas turbines.
Well known and famous for their products that feature
the Caterpillar track and distinctive yellow paint,
CAT produces a wide range of heavy equipment for
all types of jobs, including the very popular
Caterpillar D9 bulldozer.
History
The story of CAT dates back to the late 19th century,
when Daniel Best and Benjamin Holt were experimenting
with different ways to fulfill the promise that
steam tractors held for farm work. Prior to 1925,
the Holt family had pioneered track tractors and
gasoline powered engines. After the companies of
Best and Holt were merged, the company went through
several changes then at the end of World War 2,
they began to grow at a very fast pace, launching
the first venture outside of the country in 1950,
which marked the beginning of CAT development into
a big corporation.
CAT equipment ranges from track type tractors to
hydraulic excavators, backhoes, motor graders, off
road trucks, wheel loaders, tractors, diesel and
gas engines, and gas turbines. CAT equipment is
used in construction, excavation, building roads,
mining, energy, forestry, transportation, and
material handling companies.
Sales
Over half of CAT's sales are to customers in overseas
areas. CAT products are sold in almost 200 different
countries. The company has a worldwide network
of over 200 dealers - 63 in the United States and
over 150 in other countries. CAT equipment and
components are manufactured in 42 plants in the
United States and 58 plants in Australia, Belgium,
Brazil, Canada, England, France, Germany, India,
Japan, Mexico, and several other countries.
Labor
CAT almost went down in the early 1980s due to
the massive union strikes and a down turn in product
demand. At the time, several news reports indicated
that products were piling up so high in facilities
that temporary workers hired to work the lines
could barely get to their stations to perform their
jobs.
In the 1990s, CAT suffered yet another long strike
in which the company hired what it deemed to be
permanent replacements for union workers that
were on strike. During both strikes, jack rocks
were placed in the home entrances of many of
CATs top executives and employees, puncturing
the tires of their vehicles and making things
worse for the company.
Not long after the strike of the 1990s ended
and the economy started to get back up again, CAT
adopted the "6 Sigma" quality management program,
to help reduce costs and inventory and identify
and correct the defects in processes and products.

Caterpillar D Series
The CAT (Caterpillar) 420D and 430D backhoe loaders
are the high performance machines in the D series
lineup. The 420D boasts 85 HP and a backhoe digging
depth of 14 feet when equipped with a standard
stick.
The 430D offers 94 HP and a backhoe digging depth
of 15 feet when it is equipped with a standard
stick. By using an extendible stick, you can
push the digging depth of the 420D to 18 feet and
the depth of the 430D to 19 feet, which is very
impressive to say the least.
Both D series machines are available in IT
(Integrated Toolcarrier) configurations for
applications that benefit from a parallel lift
loader linkage and the versatility of quick work
tool changes through the use of a versatile
hydraulic quick coupler. Applications include the
use of pallet forks, material handling arms,
brooms, and even buckets.
The new and improved pilot operated hydraulic backhoe
and IT loader controls will help to ensure smooth,
precise operation with reduced effort on behalf of
the operator. These backhoes use excavator type
joystick controls, and an optional pattern change
valve which allows you to select the patern of
control.
The 205 degree rotation that is offered by the
backhoe bucket linkage will make it easier to dig
vertical walls and clamp material when loading
trucks. The rotation with the D series is 40
degrees more than with the C series. Now, the
backhoe buckets feature a single pin position,
with the bucket link featuring an integrated
lifting eye as well.
The optional quick coupler you can get for the
backhoe will allow fast changes of working tools
for increased versatility and flexibility in
almost all applications.
Both of the D series backhoe loaders use the
turbocharged, direct injection, four cylinder diesel
engine, with a displacement of 4.0 liters. This
engine offers superior lug performance which is
mostly due to the responsive fuel injection
system.
The standard power shuttle transmission provides
four forward speeds and four speeds in reverse
as well. Fully synchromesh in all gears will
permit on the go shifting, while the forward and
reverse electric power shuttle will provide
instant direction changes through powered
clutches.
The auto shifting feature will automatically
shift between second gear and the highest gear
selected for ease of operation. The auto shift
feature has five forward and three reverse gears,
with a transmission kick switch on the lever of
the loader control.
With D series loaders, you'll also have the choice
of standard two wheel drive or all wheel drive,
which you can engage easily on the go, under
heavy load, by pressing a switch that is located
on the front console.
The D series loaders from CAT are very fast and
versatile as well, as they will move faster than
most types of backhoes on the market. The
diesel engines are very fast, while the machine
has enough traction and control to keep you
moving even in wet or muddy conditions.
The variable load sensing hydraulic system will
adjust the flow and pressure of the machine to
meet the demands of work with an increased
pressure of 3,300 PSI. The hydraulic system is
tuned to work efficiently with the engine, and
it provides full hydraulic force to the working
tool on hand at any engine speed you desire.
Unlike other backhoe loaders, the D series will
reduce demands on the operator, cut fuel consumption
in half, reduce wear on the engine, and allow
for quieter operation. To make a long story
short - the D series from CAT are among the best
backhoe loaders that money can buy - bar none.

Caterpillar D-11
The D-11 from Caterpillar is among the series of
tracked type tractors are among the largest
conventional bulldozers in the world, second to the
Komatsu D575. It comes in two variations, the
standard D-11R and the bigger and heavier D-11R CD.
The D-11 bulldozer is among the upper end of
Caterpillars track type tractors, which range in
power and size from the D-3 (77 HP) to the D-11R
(935 HP).
The primary use for the D-11 is for moving large
quantities of rock, dirt, etc. short distances in
confined spaces. The D-11 is often times used in
quarries. The price, size, power and weight of
the D11 dictate that they are used primarily for
major products. You can normally find the D11
used in forestry, mining, excavation, and quarry
operations.
The D-11 is high known and favored for its amazing
power and ability to rip into the earth, making
them ideal for agricultural and rock ripping type
work. The ripper is the long claw like device
you can find on the back of the D-11. Rippers come
in single shank or in groups of two or more, known
as multi shank rippers. Normally, a single shank
is all you need for heavy ripping work.
The ripping of rock will allow the ground surface
rock to be broken up into small, easy to handle
and transport rubble which can then be removed
so that you can grade the area.
The agricultural ripping feature will allow rocky
or very hard ground to be broken up so that
otherwise unarable land can be put to use with
agricultural applications.
The blade on the front of the D-11 comes in 3
varieties:
1. A straight blade which is short and
has no lateral curve, no side wings, and is ideal
for fine grading.
2. A universal blade which is tall and
very curved, and has large side wings which can
carry more material.
3. A combination blade that is shorter,
has less curvature, and smaller wings on the side.
The nearest competition for the Caterpillar D-11
is the Komatsu D-475. The Caterpillar can best be
distinguished from the Komatsu by the elevated drive
sprocket or high drive system that results in a
triangular, rather than oval, shaped caterpillar
track.
The D-11 is a fine testament to the superb products
Caterpillar offers. They are great for excavation
and clearing dirt, as they can push large piles
of dirt. They are also good for rock, as they can
move even the biggest of rocks from the ground
without breaking a sweat. If you've wanted a
bulldozer with uncanny strength and abilities, the
D-11 is just what you need on your job site.

Harvester
The harvester is a type of heavy machinery that is
employed in cut to length logging operations for
felling, buckling, and cutting up trees. Normally,
a harvester is employed alongside a forward that
will haul the logs and trees to a roadside landing.
Harvesters were developed in Sweden and Finland,
and today they do nearly all of the commercial
felling in these countries. They work best for
less difficult terrain for the clear cutting area
of forest. For steep hills or removing individual
trees, chain saws are normally preferred. In
the nordic countries, small and agile harvesters
are used for thinning operations and manual cutting
is only used during extreme conditions or by self
employed owners of the forest or wooded area.
The leading manufacturers of harvesters include
Timberjack (which is owned by John Deere) and
Valmet, which is owned by Komatsu.
Normally, harvesters are built on a robust all
terrain vehicle, which can either be wheeled or
tracked. Sometimes, the vehicle can be articulated
to provide tight turning around obstacles. A
diesel engine will provide power for both the
vehicle and the harvesting mechanism through a
hydraulic drive.
An articulated, extensible boom that is similiar
to that of an excavator, will reach out from the
vehicle to carry the head of the harvester. There
are even some commercial harvesters that are
adaptations of excavators with a new harvester
head, while the others are purpose built vehicles.
The normal harvester head may consist of:
1. A chain saw to cut the tree at the
base and also to cut it to length. The saw is
hydraulically powered rather than using a 2 stroke
engine of a portable version. It offers a more
robust chain and a higher output power than any
saw carried by man.
2. Two curved de-limbing knives that can
reach around the trunk to remove branches.
3. Two feed rollers to reach out and grasp
the tree. The wheels will pivot apart to allow
the tree to be embraced by the head of the harvester,
and pivot together to hug the tree tight.
4. Two more curved knives for de-limbing.
All of this is controlled by an operator who sits
in the cab of the vehicle. A control computer is
used to simplify mechanical movements and keep the
length and diameter of trees that have been cut.
The length is computed by counting the rotations
of the gripping wheels. The diameter is computed
from the pivot angle of the gripping wheels that
hug the tree.
Harvesters are normally available for cutting trees
up to 900 mm in diameter, built on vehicles that
weight up to 20 t, with a boom that reaches up to
a 10m radius. The larger, more heavier vehicles
do more damage to the forest, although a longer
reach will help by allowing more trees to be
harvested with less movements required by the
vehicle.e

employed in cut to length logging operations for
felling, buckling, and cutting up trees. Normally,
a harvester is employed alongside a forward that
will haul the logs and trees to a roadside landing.
Harvesters were developed in Sweden and Finland,
and today they do nearly all of the commercial
felling in these countries. They work best for
less difficult terrain for the clear cutting area
of forest. For steep hills or removing individual
trees, chain saws are normally preferred. In
the nordic countries, small and agile harvesters
are used for thinning operations and manual cutting
is only used during extreme conditions or by self
employed owners of the forest or wooded area.
The leading manufacturers of harvesters include
Timberjack (which is owned by John Deere) and
Valmet, which is owned by Komatsu.
Normally, harvesters are built on a robust all
terrain vehicle, which can either be wheeled or
tracked. Sometimes, the vehicle can be articulated
to provide tight turning around obstacles. A
diesel engine will provide power for both the
vehicle and the harvesting mechanism through a
hydraulic drive.
An articulated, extensible boom that is similiar
to that of an excavator, will reach out from the
vehicle to carry the head of the harvester. There
are even some commercial harvesters that are
adaptations of excavators with a new harvester
head, while the others are purpose built vehicles.
The normal harvester head may consist of:
1. A chain saw to cut the tree at the
base and also to cut it to length. The saw is
hydraulically powered rather than using a 2 stroke
engine of a portable version. It offers a more
robust chain and a higher output power than any
saw carried by man.
2. Two curved de-limbing knives that can
reach around the trunk to remove branches.
3. Two feed rollers to reach out and grasp
the tree. The wheels will pivot apart to allow
the tree to be embraced by the head of the harvester,
and pivot together to hug the tree tight.
4. Two more curved knives for de-limbing.
All of this is controlled by an operator who sits
in the cab of the vehicle. A control computer is
used to simplify mechanical movements and keep the
length and diameter of trees that have been cut.
The length is computed by counting the rotations
of the gripping wheels. The diameter is computed
from the pivot angle of the gripping wheels that
hug the tree.
Harvesters are normally available for cutting trees
up to 900 mm in diameter, built on vehicles that
weight up to 20 t, with a boom that reaches up to
a 10m radius. The larger, more heavier vehicles
do more damage to the forest, although a longer
reach will help by allowing more trees to be
harvested with less movements required by the
vehicle.e

Case CX700 And CX330
The company of Case has done it again, by introducing
yet another spectacular excavator, the CX700, which
weighs in at 70 metric tons and represents a new
size for Case, fitting perfectly between the CX460
and CX800 models. Case has also taken advantage of
Tier 3 technologies and upgraded the CX330, increasing
the power and improving fuel economy, all while adding
features that will enhance comfort for the operator
and simplify maintenance.
Power
The CX700 is a powered by a high performance, fuel
efficient Isuzu engine that is completely Tier 3
certified. With an operating weight of 153,400 lbs.
and over 400 HP, the CX700 is capable of digging to
31 feet 11 inches with reaches up to 46 feet 11 inches.
The frame for the CX700 is based on the larger CX800
to ensure optimum durability and reliability,
especially given the powerful performance specs the
machine calls for.
New to the Case CX700 is a switch that will allow
you to give priority to either the boom or the swing
functions. The CX700 also offers retractable side
frames and an optional counterweight removal device,
which makes transporting easier than ever before.
More durable
The Isuzu engine that powers the CX700 is fully
electronic and uses a high pressure rail system that
provides a 5% increase in HP and also gives the
excavator 10% better fuel economy.
Several enhancements have been made to the CX330
upon releasing the CX700, including the overall
reliabilty and durability of the machine, which
includes the strength of the front idlers by beefing
up the thickness and design of the center hub and
improving the track seal design for increased life.
Upgrades
Several of the features that come standard with the
CX700 are upgrades for the CX330 that will also be
applied to other large Case excavator models that
move forward. The key upgrades include ease of
maintenance and servicing. Both the CX330 and CX700
models feature an easy maintenance system, lubricated
bushings throughout the boom and arm, which provides
extended lube periods of up to 1,000 hours. The
engine oil filters are now mounted vertically in
the pump house access area, which allows for easier
access and servicing.
The addition of a modified oil drain plug with a
check valve will make it easier than ever to change
oil. Both the CX330 and CX700 both offer finer
fuel filtration, up to four microns, which provides
increased uptime and improved fuel performance.
The upgraded cooling system features a design that
reduces the stacking of coolers for better cooling
efficiency and also improves access to ease the
removal of debris. In addition to this, the Case
CX700 also features a hydraulically driven,
thermostat controlled reversible fan for improving
the cooling of

Case CX330
As you may know, the CX330 is the upgrade to the
9050B model from Case. The CX330 is quite an upgrade,
being much bigger than the 9050B.
In standard form, the CX330 is almost 5,000 pounds
heavier than the 9050B. This added weight comes
from a larger counterweight and from a redesigned
carbody that will now completely enclose the swing
system.
These added pounds will also contribute to the boost
in the CX330s over-front capacity, and in combination
with higher hydraulic pressures the travel circuit,
give the excavator a very impressive 16% boost in
draw bar pull, which means more power for negotiating
poor underfoot conditions and very steep grades.
In addition to the new features, the CX330s digging
linkage has been enhanced in many ways. The boom
and arm, deeper in cross section to accommodate
higher digging forces, now incorporate V-groove
type welds that are placed by robots and 100 percent
ultra sound inspected.
The boom foot and boom to arm pivots use improved
bushings, new plated pins, and new dust seals that
combine to make a more durable and easier to take
care of assembly. The newly hardened chrome pins
will also contribute to the overall digging linkage
durability.
Even though the basic 6 cylinder, 8.3 liter engine
in the CX330 has been used in Case products since
1985, continual refinement over the years has
changed nearly 85% of the original engine's part
numbers. The CX330 features 259 net HP with an
air to air intercooler and a free breathing 24 valve
cylinder head.
The electronic logic that controls the new engine's
fuel system tracks the machine's operating parameters
and keeps the system continually armed to respond
instantly and precisely to the fuel requirements of
each individual cylinder. The total electronic
design of the engine will also eliminate cable
and step motor controls from the fuel system, with
a large gain in reliability.
Even though modest changes in the CX330s digging
linkage geometry will contribute to the higher
forces of digging, the big guns here are the
refinement of the trench with it's open center
hydraulic system. The main pressure in the
implement circuit is up almost 8%, with the hydraulic
cylinder diameter up 7% as well.
Hydraulic power
The increase in hydraulic power combines with the
more efficient linkage geometry to yield almost
20% more bucket digging force and 15% more arm
force. With 19 more HP, the CX330 can drive it's
main hydraulic pumps with much better force. In
addition, the new pumps will produce about 6% more
flow for increased hydraulic speed at much lower
system pressures.
The new PCS (Pro Control System) will manage the
hydraulic system and interface with the 6TAA-830
engine, and does it with more electronic genious
than the 9050B did. Similar to the 9050B, the
CX330 does have manually selected working modes,
although it departs from previous designs by adding
a new automatic work mode. By working in the
new automatic mode, the CX330 can analyze load
demands and operator input at the joystick, then
adjust the engine and hydraulic pumps to balance
power and speed with efficiency and even with the
economy.
Other PCS features include a high speed assistance
system, which will speed up boom and arm functions,
and an automatic power boost system as well. The
power boost system will increase main pressure by
10% for 8 seconds if the implement system reaches
the standard relief pressure for more than 1 second
in tough digging conditions.
With everything the CX330 from Case offers, it's
truly the best excavtor in years. Case has outdone
themselves this time, doing their part to make
excavating both fun and exciting. If you've been
looking for the perfect upgrade from the 9050B, the
CX330 is all that and a bag of chips.

Bulldozer
The bulldozer is a very powerful crawler that is
equipped with a blade. The term bulldozer is often
used to mean any type of heavy machinery, although
the term actually refers to a tractor that is fitted
with a dozer blade.
Often times, bulldozers are large and extremely
powerful tracked vehicles. The tracks give them
amazing ground mobility and hold through very rough
terrain. Wide tracks on the other hand, help to
distribute the weight of the dozer over large areas,
therefore preventing it from sinking into sandy or
muddy ground.
Bulldozers have great ground hold and a torque
divider that's designed to convert the power of the
engine into dragging ability, which allows it to
use its own weight to push heavy objects and even
remove things from the ground. Take the Caterpillar
D9 for example, it can easily tow tanks that weight
more than 70 tons. Due to these attributes,
bulldozers are used to clear obstacles, shrubbery,
and remains of structures and buildings.
The blade
The blade on a bulldozer is the heavy piece of
metal plate that is installed on the front. The
blade pushes things around. Normally, the blade
comes in 3 varieties:
1. A straight blade that is short and has
no lateral curve, no side wings, and can be used
only for fine grading.
2. A universal blade, or U blade, which is
tall and very curved, and features large side wings
to carry more material around.
3. A combination blade that is shorter,
offers less curvature, and smaller side wings.
Modifications
Over time, bulldozers have been modified to evolve
into new machines that are capable of things the
original bulldozers weren't. A good example is
that loader tractors were created by removing the
blade and substituting a large volume bucket
and hydraulic arms which will raise and lower the
bucket, therefore making it useful for scooping
up the earth and loading it into trucks.
Other modifications to the original bulldozer
include making it smaller to where it can operate
in small working areas where movement is very
limited, such as mining caves and tunnels. Very
small bulldozers are known as calfdozers.
History
The first types of bulldozers were adapted from
farm tractors that were used to plough fields. In
order to dig canals, raise earth dams, and partake
in earthmoving jobs, the tractors were equipped
with a thick metal plate in the front. Later
on, this thick metal plate earned the name blade.
The blade of the bulldozer peels layers of soil
and pushes it forward as the tractor advances.
The blade is the heart and soul of the bulldozer,
as it was the first accessory to make full use
for excavation type jobs.
As the years went by, when engineers needed
equipment to complete larger jobs, companies such
as CAT, Komatsu, John Deere, Case, and JCB started
to manufacture large tracked earthmoving equipment.
They were very loud, very large, and very powerful
and therefore earned the nickname "bulldozer".
Over the years, the bulldozers got bigger, more
powerful, and even more sophisticated. The
important improvements include better engines,
more reliable drive trains, better tracks, and
even hydraulic arms that will enable more precise
manipulation of the blade and automated controls.
As an added option, bulldozers can come equipped
with a rear ripping claw to break up pavement or
loosen rocky soil.
The best known manufacturer of bulldozer is CAT,
which has earned a vast reputation for making
tough and durable, yet reliable machines. Even
though the bulldozer started off a modified farm
tractor, it rapidly became one of the most useful
pieces of equipment with excavating and construction.

Backhoe Loader
Also referred to as a loader backhoe, the backhoe
loader is an engineering and excavation vehicle that
consists of a tractor, front shovel and bucket and
a small backhoe in the rear end. Due to the small
size and versatility, backhoe loaders are common
with small construction projects and excavation type
work.
Originally invented in Burlington Iowa back in 1857,
the backhoe loader is the most common variation of
the classic farm tractor. As the name implies, it
has a loader assembly on the front and a backhoe
attachment on the back.
Anytime the loader and backhoe are attached it is
never referred to as a tractor, as it is not normally
used for towing and doesn't normally have a PTO.
When the backhoe is permanently attached, the
machine will normally have a seat that can swivel
to the rear to face the backhoe controls. Any type
of removable backhoe attachments will normally have
a seperate seat on the attachment itself.
Backhoe loaders are common and can be used for many
tasks, which include construction, light transportation
of materials, powering building equipment, digging
holes and excavating, breaking asphalt, and even
paving roads.
You can often replace the backhoe bucket with
other tools such as a breaker for breaking and
smashing concrete and rock. There are some loader
buckets that offer a retractable bottom, which
enable it to empty the load more quickly and
efficiently.
The retractable bottom loader buckets are often
times used for grading and scratching off sand.
The front assembly on a backhoe may be either
removable or permanently attached. Often times,
the bucket can be replaced with other tools or
devices. In order to mount different attachments
to the loader, it must be equipped with a tool
coupler. The coupler consists of two hydraulic
cylinders on the end of the arm assembly, which
can expand and retract to allow different tools to
be attached to the unit.
There are several types of backhoe loader brands,
including New Holland, John Deere, and Case. Some
will offer you cabs, while others won't. The
newer types of backhoe loaders even offer you air
conditioning, radios, and other accessories that
make you feel like you are working with luxury.
Common with excavating jobs, the backhoe can serve
many purposes. It can haul equipment and supplies
in the loader bucket. Another great use is to cover
up dirt when filling in trench lines or covering
up pipe that was just put in the ground. The
backhoe attachment at the rear is ideal for digging
water pipes and sewer pipes.
The best thing about the backhoe loader is the
fact that they are easy to operate. You don't
need to be a rocket scientist to fully operate this
nifty piece of equipment.

up pipe that was just put in the ground. The
backhoe attachment at the rear is ideal for digging
water pipes and sewer pipes.
The best thing about the backhoe loader is the
fact that they are easy to operate. You don't
need to be a rocket scientist to fully operate this
nifty piece of equipment.
