we build undercarriage compo

to work within integrated sys

provide exceptional reliabi

and durability, and wear at

balanced rate.

As a result, you will be able

VH StyleRetracted

These unique arrangements can be

extended to wide-gauge congurations

or increased stability in applications

such as box boom cranes, lattice cranes

or oundation drillsand retracted to a

narrow-gauge congurtion or

easier transport.

VH style undercarriage eature an H

style carbody that allows the individual

track-side rames to be extended/retracte

through the use o our hydraulic cylinder

mounted inside the H legs.

VM style undercarriage eature a square

style carbody that extends/retracts using

legs that are welded to the track-side

rames and actuated through two

hydraulic cylinders.

Both arrangements can accept a wide

variety o track shoes. Additionally, they ca

be congured to accept standard Cat swin

bearings and upper structuresor be

customized to suit most OEM requirments.We can also adapt a range o Cat nal

drives and travel motors to help ensure

your arrangement will meet your

particular needs.

Hardened for long wear life,

unmatched structural support

and resistance to deormation.

Sealed and Lietime Lubricated

with Cat Duo-Cone Seals.

tc roesAvailable with single or double

fange in both excavator and

track-type tractor styles.

Wide langes resist rollover.High-strength steel and deep

hardening virtually eliminate

wear, shock loads and bell

mouthing. Sleeve bearings and

large, hardened shats absorb

impacts and defection.

Ce roesIncorporate large shats

and bearings to promote

longer component lie.

Cantilever-mounted tominimize material build-up

and provide easier cleaning.

Hardened rims resist

cracking and chipping.

Star rOllErS

These optional rollers will

continue turning in applications

where materials build up, or

reezing and thawing conditions

exist, eliminating fat spots thatcan occur on traditional

carrier rollers.

Manuactured or excellent wear

resistance, strength and durability.

Special heat-treatment processes

produce consistent surface

hardness, superior hardened

depth and strong core hardness.

linkSiDlErS

Cast or abricated with internal

reinorcing plates or superior

strength and durability. Sealed

and Lietime Lubricated with

Cat Duo-Cone Seals.

SprOCkEtS

Superior surace hardness, hardeneddepth and core hardness provide

long wear lie, resistance to bending/breakage and maximum hardware

retention. Available in three styles.

tc adjsg & recoSg GosHeavy-duty recoil springs reduce

shock loads. Hydraulic track

adjusters can be set with agrease gun (no special servicetools or high-pressure gas-charging

cylinders required).

GrEaSE luBriCatEDtraCk (Glt)

Providing high wear lie with low

maintenance costs, Cat tracks

and track components continue

to perorm in the eldyear

ater year, decade ater decade.

Gese lbced tcResin seals retain a protective

layer o grease between the

pin and bushing. GLTs provide30% longer wear lie than

other sealed track assemblies,

allowing or longer sprocket lie,

lower risk o rozen or seized

track joints and reduced

undercarriage noise. Available

on most 300 Series hydraulic

excavators, GLTs can be used

to replace link assemblies on

earlier models.

Seed tcsUse belleville-type washers

between the bushing and link

counterbore, and oer longer

lie o the pins and bushings than

unsealed systems. Heavily strutted

links, cold-extruded bushings,

induction-hardened pins, and

other eatures contribute to

durability and dependability.

traCk SHOES

Rolled rom modied medium carbon

steel and deep-hardened or long

wear lie. Heavy cross-sections with

curved leading and trailing edges

resist bending. Available in a wide

range o styles and widths.

tc Shoe HdweIncludes sel-locking track nuts

and bolts that match shoe strength,

exceeding SAE Grade 8 standards.

Rolled threads resist stripping and

cross-threading. Controlled stretch

allows uniorm tightening procedure.

SEalED & luBriCatED traCkS

Provide longer bushing wear

lie than sealed non-lubricated

systems, eliminating iternal

pin wear, reducing noise and

lowering operational and

maintenance costs. These tracks

are available in standard and

heavy-duty congurations.

Hey-Dy tcsThese tracks are built to meetthe challenges ounderoot

conditions created by side-sloping,

rocky or uneven terrain. Specially

designed links, pins and bushings

handle high-impact load and

stresses, and eature more rail

wear material or approximately

20% longer extended system lie

than the GLT assembly and

50% more than the sealed

track assemblies.

ps & BshgsDimensionally matched to the

links, and manuactured to provide

excellent track joint integrity and

sealability. High surace and core

hardness increase strength and

wear resistance.

SElECtiOn anDappliCatiOni CosdeosAppropriate components must be suited to

the machine size (gross vehicle weight) and

intended application (underoot conditions,

machine speeds, travel distances and

maneuverability requirements). Additionally,

components that provide balanced wearrates and lower operating/maintenance

costs will help to enhance the liecycle

value o the equipment.

Seecg tc Shoes Single Grouser Shoes provide good

penetration and traction.

Double Grouser Shoes oer less turning

resistance or greater maneuverability.

Triple Grouser Shoes oer the lowest penetration

and resistance and best maneuverability. Special Use Shoes, such as fat, sel-cleaning,

and rubber/polyethylene-bonded, are available

in some sizes.

Extreme Service Shoes provide longer wear

in high-impact and abrasive conditions.

Me those tcs lsTo help your customers gain the best perormance

rom your machines, encourage them to:

Minimize high operating speeds in

nonproductive situations.

Adjust the track or correct tension in the

working environment.

Make daily visual inspections o the equipment.

Keep the undercarriage clean o mud and debris.

Seecg roes Excavator-style rollers eature a

straight, large-diameter shat.

Recommended or machines that

must operate in high-impact

conditions and travel at slow speeds.

Track-type tractor rollers are recommended or higher speed applications and oer increased wear lie over excavator-style rollers.

Seecg Soces

To equalize sprocket wear, select sprockets that utilize

an odd number o sprocket teeth. The resulting hunting

tooth design ensures that teeth contact a bushing on

every other revolution.

Bolt-on rims are easy to replace, reducing downtime

and maintenance. Replacement usually requires

removal o the track group.

Bolt-on segments are also easy to replace, urther

reducing service-related costs. Replacement can

usually be perormed without removal o the track

group. Recommended when high sprocket wear

is anticipated.

Weld-on rims oer a lower initial cost, allowing you to

balance machine perormance and value. Used where

sprocket lie is not critical.
