Abstract: The lift is installed under the cargo floor proximate to the side door of the van. In the retracted position it is entirely concealed and does not obstruct the normal van usage. Stationary track members are attached to the van. Slidably mounted within the track members are frame members which may be extended or retracted from the van by use of a pair of worm gears. A pair of hydraulic cylinders interconnect the platform and the frame using four links which raise and lower the platform equalangularly. The equalangular motion of the links maintains the platform in a substantially horizontal position as it is lowered from its raised position level with the floor of the van to its lower position with the street or sidewalk.
