An elevator comprising a self-propelled truck and a cab secured thereto and for use especially for transporting invalids and convalescents, the cab being adapted to be selectively lowered or raised relative to ground level by means of a vertical two-stage mast assembly. Electric motors within the truck hydraulically power the mast assembly, front wheels and the steering mechanism of the single rear wheel. Further electrically operated are interior lights, a courtesy light, windshield wiper and defroster fan and a bell effective to provide a warning when the cab is lowered or when the truck is moved in reverse. The square-shaped cab is further provided with all-around tiltable windows, a vent in the cab ceiling, wide sliding doors to facilitate easy access and exit, and bumpers in the cab lower contact areas. A manually positionable ramp aids a wheelchair passenger while boarding or leaving the cab, and an inner foldable safety railing further affords additional safety and support for such passengers.
