ABSTRACT:
A crawler track support system is disclosed which is particularly suited for embodiment in a material handling implement, such as a crawler excavator. The support system permits selective alteration of the length of the ground-engaging portion of a crawler track, thus permitting maximum ground contact which is necessary for traction and support, and also permitting reduced track ground contact for improved mobility. Significantly, the present support system is very straightforward in construction for economical manufacture and reliable operation. If desired, the present support system can be adapted to provide shock absorption for the implement, which can be particularly desirable when traveling at relatively high speeds.
