This is a rotary loader for transfer of cargo containers, flat beds or pallets, racks, or other loads to and from railroad cars or vehicles moving by and is rotated to turn either end to a dock or building for convenient end loading. Standard or wide end-door cargo containers can be transferred and supported on the loader and the loader turned so the door end of the container is at or over a dock so fork trucks or other vehicles can be driven over a dock board straight in and out from the cargo container. One form of the loader has two vertical posts equally spaced from a railway track or driveway and a horizontal rotary arm connected on each post to rotate parallelly through an arc with cam lift for transfer as my earlier loader, but the arms are free to be rotated differently from dead center position to rotate either end of the load to the dock or building doorway. The loader can be rotated to and from the dock by hand or by cable and winch or by a separate reversible drive or motor for each arm. The preferred loader features shiftable support wheels for alternately running two concentric cam track rings about each pivot post, the rings about each post being connected by a transfer-slope-crossing into one continuous cam track for transfer to or from a train in either direction. The loader and vehicle have auxiliary side couplings and controls to start the loader to side couple the moving vehicle for transfer. Another form of the loader has two arms for transfer of the load, but only one of these substantially supports the load.
