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.

Abstract: Described is a mechanical lift for lifting (or lowering) an object to (or from) an elevated storage compartment. The lift comprises a carriage in which the object, for example an oxygen tank, is secured. Rigid bars are pivotally mounted to an upper portion of the carriage and to a lower portion (e.g., floor) of the compartment. Preferably, the bars are mounted on opposite sides of the carriage. A telescoping rod is pivotally connected to the upper portion of the carriage and to an upper portion (e.g., ceiling) of the compartment. Spring means, which extends between substantially the same points as the telescoping rod, counterbalance the weight of the object when it is being lowered out of or lifted into the compartment.
