ABSTRACT:
This is a top-lifting rotary loader and system especially suited for loading and unloading double stacking container well cars. This loader has a self-aligning loadspreader on a crane lift arm extended to revolve around and swing up and down from a vertical column. Each lift arm comprises a first parallelogram linkage with generally horizontally extending links to swing up and down from the column, and a second parallelogram linkage with generally vertical links pivotally attached to the outer lift end of the first linkage and extending to support a loadspreader free to turn thereon. The loadspreader has vertical alignment and coupling rods which turn the loadspreader to align and engage in pockets on the vehicles. A lift cylinder and/or cam track supports the arm to rotate on the column and set and pick up containers. The column can be supported on the ground if vehicles are to be moved past for loading and unloading, or the column and concentric cam track can be supported on a railway truck on a track and the column held vertical by a half-gantry on wheels on a rail parallel that for the railway truck and along the opposite side of a track or driveway for standing vehicle loading and unloading or the column can depend from a traveling gantry especially for the loader to clear over stacked containers. The loadspreader can engage the usual corner castings on the containers or novel automatic hooks especially for models and toys are provided.
