ABSTRACT:
A wheelchair lift which permits the wheelchair to be lifted to an appropriate height by means of a vertically adjustable pedestal including telescoping circular cylinders. The pedestal also includes a generally circular base of a predetermined height for housing the lifting cylinders, a typical example being a hydraulic unit for lifting a barber chair. The lift comprises a pair of elongated generally parallel upwardly facing channel members disposed on either side of the pedestal base for receiving and supporting the wheels of a wheelchair which has been rolled into position thereon. The parallel channels are connected to the uppermost lifting cylinder by means of a downwardly facing channel member which includes a top portion secured to the lift cylinder and two side arm portions extend outwardly and downwardly over the base where they are attached to the parallel channel members intermediate their length. A flat plate extends between the two parallel channel members at the front part thereof for providing not only structural support, but also an entry ramp for the wheelchair.
