Abstract
A cargo ramp configured for stowage on a cargo carrying vessel and deployment between a cargo opening or the outer boundary of a cargo deck and the surface of a cargo handling region such as a runway, dock or pier. The cargo ramp includes two hinged together ramp sections having a motor-driven wheel assembly at the lower terminus of the ramp and a vessel-to-ramp interface at the upper terminus of the ramp. Deployment and retrieval of the cargo ramp is effected through predetermined sequential operation of motor-driven deployment wheels located beneath the upper ramp section, actuators for operation of the hinge and the motor-driven wheel assembly at the lower terminus of the ramp. A power operated deployment mechanism contained in the ramp-to-vessel interface permits vertical adjustment of the upper terminus of the ramp when required. The ramp-to-vessel interface and the wheel assemblies at the lower terminus of the ramp are configured to permit various deflections and movement that can occur during deployment, retrieval and use of the cargo ramp.
