Abstract: A movable frame is adapted to be loaded onto and unloaded from a stationary frame mounted on a vehicle. A platform is releasably mountable onto said movable frame. The platform and movable frame may be hoisted simultaneously when being loaded and unloaded from the stationary frame. The platform includes a downwardly depending support legs which are of sufficient length to maintain the platform elevated above a first portion of the movable frame which is inserted under said platform when said movable frame is resting in a lowered position when unloaded from the stationary frame. The movable frame may be raised to engage with the underside of said platform. Interlocks cooperate between said platform and said movable frame so that the movable frame centers onto and mates with said underside of said platform.

Abstract: A loading apparatus for a vehicle, the apparatus having a first frame; a second frame having a chain mounted thereupon; and a locking system that is mounted on the first frame. The locking system has a drive wheel, a first arm member and a second arm member. The system is configured such that in a generally closed position, the chain engages the drive wheel in a first position, the drive wheel is connected to the arms; the arms are urged into the closed position. In a generally open position, the chain engages the drive wheel in a second position and the arms are urged into the open position by the second frame.
