ABSTRACT:
This is a top lift rotary-crane transfer device and system especially suited for transferring cargo containers between a railway car and one or more conveyors or other vehicles or storage spots. It has a revolving loadspreader on the end of a revolving crane connected by chain and sprockets or gearing to cancel to hold the loadspreader in parallel positions while translating around a supporting column. Improved alignment columns on the loadspreader are carried above the ground and swing up to clear over containers set on a conveyor. The alignment columns align the loadspreader transversely over a container, well car, flat-bed trailer, or along a conveyor. The alignment of the loadspreader can be turned if desired to engage one end first and help clear an adjacent car. The loadspreader can be suspended on swinging links and be swung back from a vehicle to increase clearance over adjacent vehicles or loads; or the loader can have its positioning arm retractable to increase this clearance and extensible to position the loadspreader over a vehicle.
