D7H/R GENERAL DUTY
UNDERCARRIAGE INTRODUCTION
AVSpare
introduces Cat? General Duty Undercarriage. AVSpare created
the new line for Cat machines operating in lower usage or lighter duty
applications where the full value of Heavy Duty Undercarriage is not
realized. General Duty Undercarriage is
AVSpare designed and
available exclusively through Cat dealers. The D7H/R model is the first
machine that will have the General Duty Undercarriage option made available.
Additional machine models will follow this offering in the future.

Requires minimum maintenance using standard inspections
-
Checking for loose or broken hardware, leaks, dry joints, shoe overlap, etc.
-
-
