Abstract
A ramp assembly is provided. The ramp assembly includes a frame, a ramp platform, and first and second locking mechanisms. The ramp platform is mounted in the frame defining forward and trailing ends, and is extendible and retractable along a length of the frame between a stowed and a deployed position. The ramp platform is arranged such that when deployed the forward end extends down towards the ground. The first locking mechanism locks the ramp platform into a fully deployed position, and the second lock mechanism locks the ramp platform into a fully stowed position. The ramp assembly also includes a manual release mechanism, the actuation of which releases the first locking mechanism when the ramp assembly is in the fully deployed position. The actuation of the manual release mechanism also releases the second locking mechanism when the ramp platform is in the fully stowed position.
