Abstract: A lift system for a wheelchair or the like on a transit vehicle includes a stationary main frame secured within a doorway recess of the vehicle and a side frame that is movable relative to the main frame. An articulated platform including first and second steps is pivotally secured to the side frame. Scissors linkage is pivotally and slideably connected to the main frame and to the platform such that upon being actuated, the platform may be actuated from a first position defining first and second steps to a second position defining an extended platform. Thereafter the platform may be actuated in a manner such that the scissors linkage crosses over its center point to lower the platform from the floor level of the vehicle to the ground level. Once the wheelchair or the like is mounted on the platform the reverse actuation occurs and the scissors linkage again crosses over its center point to raise the platform from the ground level to the floor level.
