ABSTRACT:
A retractable ramp is described for loading heavy objects into a vehicle, for example, for lifting a stretcher and patient up onto the floor of a modular ambulance, or rescue vehicle body. The ramp, which is stored on guides below the floor when not in use, comprises a retractable lower frame to which a ramp incline is hinged at its exterior end. The incline includes a pair of spaced, parallel, U-shaped channels. When in use, the lower frame is retracted, the incline is raised and secured to the floor and then the wheels of a stretcher are placed in the channels so that the stretcher (and patient) can be rolled up onto the floor by pushing the stretcher up the incline rather than by lifting.
