Undercarriage

Solutions to lower your costs per hour.

Choice of Undercarriage Configurations to Meet Your Application

Track frames are available in extra long (XL) or low ground pressure (LGP) configurations:

XL undercarriage for most applications where flotation and side stability are not extreme
LGP undercarriage for soft underfoot conditions where additional flotation is required

Track Selections

Caterpillar offers a choice of two undercarriages – Sealed and Lubricated Track (SALT) and SystemOne™. Matching the correct undercarriage to the application and soil conditions will deliver the lowest costs per hour.

Sealed and Lubricated Track (SALT) Undercarriage – For applications where the track is not bushing limited – May require pin and bushing turn

AccuGrade™ Systems

Grade with increased accuracy.

Improve Your Efficiency with AccuGrade

AccuGrade is a fast machine grade control system which enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional stakes and grade checkers. Caterpillar offers a choice of Laser, GNSS or Universal Total Station solutions:

AccuGrade Laser – for two dimensional flat type work
AccuGrade GNSS – for three dimensional cut to contour work
Universal Total Station – for fine and finish grade applications

New Larger Displays
