Abstract: A trailer frame storage system comprises a plurality of storage units connected closely together in laterally spaced apart condition, each storage unit having a plurality of longitudinally spaced, folding trailer frame support arms each arranged to receive and support a trailer frame for storage in a substantially vertical position in which the trailer frame is rested on its rear end on the ground and its forward end extends upwardly. Each arm is extended, one at a time from rear to front, by movement of the next rearward arm to fully extended position as a trailer frame is rested against it, the frames being transported longitudinally into the storage unit, successively filling the unit from the rear end to the front end. Removal of the stored trailer frames follows the reverse order, and removal of each frame results in it engaging the next adjacent forward arm from which a trailer frame has been removed, to cause said forward arm to be moved toward retracted position.

Abstract: A straddle carrier for handling cargo containers is shown having a rectangular elevated frame with a trolley that travels back and forth over the area defined by the frame, a pair of forward support columns mounted on wheels that are located outward from the sides of the elevated frame and rearward from the front of the frame, a pair of rear support columns mounted on wheels that depend from the rear of the frame which are obliquely disposed to be closer to one another at ground level and spread apart at their juncture with the frame, and load grappling means supported from the trolley.
