ABSTRACT:
The base frame of a crawler truck for cranes or similar heavy equipment is provided on at least two opposite sides with projecting heavy attachment plates which coact with support structures projecting in an opposite direction from the side frames of self-contained crawler assemblies requiring attachment to the truck base frame. The side projecting structures of the crawler frames include permanent upper mounting pins and lower mounting openings. The upper pins rest within seating notches formed in the heavy attachment plates of the truck base frame and the lower mounting openings receive reciprocatory lower mounting and locking pins of the crawler assemblies, which pins are connected with power-actuators on the crawler assemblies. Safety latches prevent premature withdrawal of the lower pins from their mounting and locking positions. Awkward and tedious alignment problems are avoided.
