ABSTRACT:
This is a top-lifting rotary loader and system for cargo containers and is especially suited for loading and unloading double-stacking container well cars and single level railway cars, semitrailers, etc. This loader has a vertical pivot post about which turns a parallelogram linkage connecting a mast vertically supported on one or more wheels to revolve about the post and a second parallelogram linkage extending from the mast out to support a depending parallelepiped linkage frame pivotally supporting a loadspreader having depending aligning columns adjustable to align transversely both a railway and a highway vehicle, and cylinder or cam track means for lifting or lowering the the second parallelogram linkage arms to transfer a load. The loader can be automated to various degrees with cam tracks. The loader can be operator controlled, the cam track can set the height for its loadspreader to clear the container over the vehicle and the operator control the dip for transfer or the cam track can have dips to lower and lift the container. Cam tracks can operate the loaders for one or more levels of transfer. The masts run up and down inclines as the cam wheel runs down and up oppositely on slopes in the cam track to lift and lower the crane to balance out the lift slopes and reduce the size of the dip in the cam track. The cars are moved by car movers to the rotary loader for transfer. The car's well and top level are loaded or unloaded by loaders on opposite sides of track preferably a car length apart for quick loading. The vertical pivot column can be mounted on top of a traveling gantry so the mast can run around the gantry when the gantry is stopped and the drive for the mast be used to move the gantry.
