Abstract
An improved arrangement for adjusting crawler-type transport assemblies in a self-propelled construction vehicle between two differing “home” positions. The crawler transport assembly comprises a steering mechanism including a collar assembly operated via an actuator mounted to the frame of the apparatus for driving steering rotation of the transport assembly via the collar assembly. The collar assembly comprises a driving element integrally coupled to the actuator and a driven element integrally coupled to the transport assembly. The driven element can be affixed to the driving element selectively in two differing dispositions corresponding to the two “home” positions of the transport assembly.
