The Caterpillar elevated sprocket undercarriage arrangements allow optimized balance for the best possible performance in each application.
Final Drives Final drives and associated power train components are raised above the work area - isolating them from ground-induced impact loads, as well as implement and roller frame alignment loads - extending power train component life.
Sprocket Position The sprocket position keeps sprocket teeth, bushings and final drives away from the abrasive materials and moisture - resulting in longer final drive gear and seal life.
Heavy-Duty Sealed and Lubricated Track The heavy-duty sealed and lubricated track is designed for superior track life. A wider bushing strap provides improved bushing retention and resistance to bore stretching and cracking.
High Flange Improved Track Rollers High flange improved track rollers (optional) combined with center or full length roller guard attachments greatly improve track guiding for demanding side slope or impact conditions.
Rotating Bushing Track Rotating bushing track (optional) is a sealed and lubricated system which includes four track seals per joint, non-restrained floating bushings, longer track pins, redesigned track links and a unique pin retention system.
General Purpose Undercarriage The D6R features general purpose undercarriage that performs well in many applications with firm underfoot conditions.
Heavy-Duty Track Link Heavy-duty track link is standard on all D6R configurations.
