OF ALL!

In case you were wondering . . .

The vehicles in this book are called

Caterpillar machines because

one of the Caterpillar company

founders, Benjamin Holt, came up

with the idea to replace wheels

with tracks. When a photographer

was asked to take pictures of these

tracked machines crawling all over

the ground, he remarked that they

looked like gigantic caterpillars.

These are early Caterpillar tractors.

SOIL COMPACTOR MATERIAL HANDLER BULLDOZER HYDRAUL

The BULLDOZER

can use the teeth

on its multi-shank

ripper to bite into

concrete and tear

it apart!

This HYDRAULIC

EXCAVATORcan

dig a hole 31 feet

(9.4 meters)

deep! The MOTOR GRADER

makes the ground flat for a

new roadbut it can also be

a snowplow!

The SKID STEER

LOADERcan be a stree

sweeper, a snowblower,

and a jackhammer, too!

This MATERIAL HANDLER

has an arm so long it can stretch

across a basketball court!

EXCAVATOR WHEEL LOADER MINING TRUCK

This WHEEL LOADERis so big

that its wheels alone are 12 feet

(3.7 meters) tall!

This MINI-

EXCAVATOR

sure looks small,

but its so strong,it could lift the

weight of three

cows!

ThisARTICULATED

TRUCKis strong

enough to carry around

31 tons (28 tonnes),

which is about the

weight of 52 polar

bears!

The BACKHOE LOADERcan

do twice the work of most machines

because it has attachments on

both ends!


8/14

The SKID STEER LOADERmay be the smallest of the

trucks in this book, but its a very useful machine. This nearly

6,000-pound (2,722 kg) vehicle moves quickly and easily, and it can

do lots of different jobs, like digging, dumping, hammering, raking,and even snow blowing!

SKID STEER LOADER

The operatorenters thecab through

thisDOOR.

Skid steer loaders use an

attachment called a cold

planer to repair concrete,

remove bumps in pavement,

and smooth surfaces so new

pavement can be laid down.

The operator sitsin theCABin anadjustable seat.

This loader is using a

grapple fork to handle

these bulky, loose, and

oddly shaped objects.

This skid steer

loader is using its

angle broom to

sweep the streetclean.

The BUCKETisdesigned to dig, load,and carry all sorts ofmaterials, like rocks,dirt, plants, and more.

The TIREShave extralarge treads for tractionon all sorts of surfacesfrom dirt to rock to snow

to pavement.

The joystick on the right side

of the cab is used to control

the loader that holds the

attachments. The left joystick

moves the vehicle forward

and backward.


10/14

This mini-

excavator is

using its auger

(a large drill) to

dig a hole so a

shrub can be

planted.

The hydraulic hammer

works like a jackhammer

to smash rocks into tiny

pieces.

MINI -EXCAVATOR

It may be called a MINI-EXCAVATOR, but this small machine

is mighty. It can dig, lift, carry, and dump. In fact, it can lift over

3,000 pounds (1,364 kg) and dig a hole 15 feet (4.6 meters) deep.

These machines are useful for digging in areas where a largerexcavator would be just too big to fit.

The end of thearm is called

the STICK,and it holds thebucket or otherattachments,like hammers oraugers.

TRACKS


11/14

This wide bucket is used to clear out ditches.

The BUCKETdigs into the groundand scoops dirt androcks.

The CABcontains allthe levers, pedals, andjoysticks the operatorneeds to control theexcavator.

The mini-

excavator can

lift over 3,000

pounds (1,364

kg). Thats more

than the weight

of three cows!

This BLADEpushes dirt.


12/14

The TELEHANDLER is used to lift things high into the air.

It has a long arm called a telescopic boom that slides out like a

telescope. This arm can have many different attachments at the

endlike a bucket or a forklift, to name just two.

TELEHANDLER

This telehandler can stretch

out its boom to lift anything

even peopleas high as 55

feet (16.8 meters) in the air.

Thats as tall as three giraffes!

BOOM

Farmers use telehandlers to transport

bales of hay. Since telehandlers can

carry up to 5,000 pounds (2,268 kg),this 1,500 pound (680-kg) hay bale is an

easy job!


13/14

GRAPPLE

FORKS

The CABissoundproof toprotect theoperators ears.

This telehandler is using its block fork tines

(large metal prongs like those on a dinner

fork) to lift a stack of concrete slabs to the

very top of a new building.

Telehandlers use a special attachment called a

grapple bucket to move and lift bulky objects like

this pile of hay.

BUCKET


14/14

The BACKHOE LOADER does twice the work of most

machines. Thats because on one end it has a loader that holds

buckets, forks, and brooms. On the other end, it has a backhoe

that holds buckets or hammers. This machine is a specialist atroad building because it can dig, lift, and carry dirt and rocks to

clear the way for new streets.

BACKHOE LOADER

The bucket can carry

up to 9,500 pounds

(4,309 kg). Thats

the weight of four

compact cars.

The huge teeth on this bucket

help to break up the dirt as the

machine digs into the ground.
