Abstract
A self-storing lift gate assembly for trucks or the like in which a lift platform may be selectively located in an operative load lifting relationship upon a power driven lift linkage or in a compact folded stored position upon the linkage. The platform is so arranged that, when stored, the lift linkage underlies and supports the platform and releasable latch means are engaged between the platform and the assembly frame to retain the platform and linkage in the stored position. The latch means includes one or more pins on the platform which, when the platform is in its operative load lifting relationship relative to the linkage, engage a bed extension plate to establish the upper limit of movement of the platform and to restrain the platform against transverse movement relative to the frame, such as might be encountered during transferring articles between the platform and the load carrying bed of the truck.
