ABSTRACT:
There is described a new and improved self-propelled steerable gantry crane including an elevated load carrying beam, individually adjustable downwardly divergent pairs of legs spaced apart lengthwise of the beam proximal the ends thereof for supporting the beam, a tie rod between the lower ends of the legs to maintain and adjust the angularity between the legs and ground engaging mobile mountings for the gantry. The ground engaging mountings include a castering wheel disposed adjacent the lower end of one of each pair of the downwardly divergent legs to swivel about an upright axis perpendicular to the longitudinal axis of the tie rod, a fixed orientation wheel disposed adjacent the lower end of the other of each pair of legs to be aligned with the longitudinal axis of the tie rod, a motor operatively connected to each of the fixed orientation wheels to independently rotate the wheels in a forward or reverse direction and control means to independently actuate the motor for forward or reverse rotation of the fixed orientation wheel.
