Abstract
Abstract A vehicle-mounted apparatus for lifting and transporting a wheelchair is provided comprising a base onto which the power wheelchair is driven and parked, and having a motorized lift mechanism which lifts the base and wheelchair to a height necessary for transport wherein the base is provided with a subassembly which will keep the base from yawing about the axis formed by the lifting mechanism. Additional subassemblies are provided which hold the wheelchair on the base once it is in the raised position.
