ABSTRACT:
Disclosed are systems and related methods for mounting a ground-engaging motive device, such as a crawler track assembly, to a vehicle, such as a crane or the like, in either an extended or a retracted position. The systems and methods are adapted to ensure that proper alignment is reliably achieved between the mounting structures on the motive device and the corresponding mounting structures on the vehicle in both the extended and retracted positions. In one embodiment, the system and method are especially adapted for use in extending the crawler track assemblies on certain types of existing cranes without the need for extensive retrofitting.
