ABSTRACT:
This loader has two rotary arms which turn a load spreader fork frame off-parallel so that only one fork is extended to couple. The fork frame has a fork at each end with a cam track diagonal across the bottom engaged on the extended fork by a coupling roller extended from a vehicle to pull the fork frame to the vehicle until the roller leaves the track when the frame has engaged between pedestals on the vehicle. The frame is engaged and rotated through many more degrees and the most effective degrees of a circle for a transfer run (now over 180.degree.) than by the side coupling of my prior loaders, thus enabling the loader to have shorter rotary arms and to extend out over the vehicle with less travel lengthwise of the vehicle so the rotary arms can be shorter and the fork narrow to fit between conveyor runs for a shorter container to be transferred between the conveyor and the vehicle (usually a railway car or semitrailer) and so the fork frame can fit between the trucks of the car or wheels of the tractor-trailer so the container is carried lower and can be larger. The fork frame pivots move in arcs tangent alongside of the open center sill of the vehicles to further shorten the load arms and to reduce the required height of the vehicle's pedestals for the load.
