ABSTRACT:
A manually operated ramp assembly includes a ramp platform and a drive assembly. The ramp platform is moveable between a stowed position and a deployed position, and the drive assembly is coupled to and affords movement of the ramp platform. A shaft extends away from the drive assembly and defines a shaft axis. The shaft is coupled to the drive assembly to cause movement of the ramp platform between the stowed position and the deployed position in response to rotation of the shaft about the shaft axis. A handle is disposed at a distal end of the shaft for manual rotation of the shaft about the shaft axis. A biasing member biases the ramp platform toward the stowed position.
