Abstract
A crane and lift apparatus for controlling the operation of primary hoist and bridge structure, and gantry drive functions of the equipment. There is provided an auxiliary hoist grapple apparatus to unload containers stacked one above another from one location to another parallel thereto, from one roadway to a parallel roadway, or from one flat bed railroad car to another flat bed railroad car disposed upon a track that is parallel to and adjacent to the track on which the first railroad car is located. The apparatus is adaptable to straddle two locations, parallel roadways, or parallel railroad tracks and effect interchange of containers to and from trucks or railroad cars positioned on the parallel roadways or tracks. The apparatus permits locking of the main stabilizing beam at an uppermost position to clear double stacked containers and provides secondary vertical motion so as to reach down adjacent the stacked container and pick up a container from a lower most position resting on the ground or from a truck or a flat bed railroad car. The apparatus permits selective raising and lowering of cable supported containers up to as much as thirty feet from ground level.
