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.
A rolling mast rotary loader for transfer of cargo containers between railway cars and semitrailers comprising, a vertical pivot post, a mast, substantially horizontal parallel arms pivotally linking said mast to said post vertically forming a parallelogram linkage for supporting said mast vertically, motorized wheel means supporting said mast to roll in an arc of a circle around said post, a crane comprising parallel arms pivotally secured one above the other to said mast and a vertical load support member forming therewith a second parallelogram linkage mounted on said mast having arms extending in a plane parallel to the first said parallelogram linkage out further from said mast, a top frame supported on said load support, member a bottom frame, parallel links connecting said top and bottom frame on each side forming a parallelopiped linkage supported by said vertical load support member and free to swing said bottom frame out and back substantially parallel to said arms, a loadspreader pivotally supported to rotate horizontally on said bottom frame of said parallelopiped linkage, means for lifting and lowering the crane's arms to lift and lower said loadspreader relative to said mast, and means for rotating and moving on said loadspreader on said parallel links to align the loadspreader for transfer over both the railway car and the semitrailer when revolved thereto.
A rolling mast rotary loader for transfer of loads, comprising:
