ABSTRACT:
Lift mast transporting arrangements frequently encounter loading which is detrimental to its operation and life. A transport device connects a lift mast assembly to first and second spaced apart guide rails and guides movement of the lift mast assembly along the guide rails, a power device having a shaft moves the transport device along the first and second guide rails between first and second spaced apart positions, and a coupling connects the power device to the transport device and provides a preselected amount of free movement of the transport device relative to the shaft and in directions transverse of the first and second guide rails. Thus, the aforementioned problems related to loading of lift mast transport arrangement is alleviated. The lift mast transporting arrangement is particularly suited for use on a material handling vehicle.
