A wheelchair lift apparatus for transporting a wheelchair and its occupant into and from a commercial vehicle can be installed in the existing doorway of the vehicle on a rotation column which is capable of supporting a telescoping platform assembly for movement into and out of an operative position across the doorway, there being a retention strap to prevent accidental forward rolling movement of the wheelchair as it is lifted or lowered, and a barrier plate across the front end of the forwardmost platform section cooperates with side flanges or rails on the platform section to prevent accidental movement of the wheelchair off of the platform assembly. The platform support unit is capable of lifting and lowering substantial loads without binding, and the platform assembly is hinged to the platform support unit in such a way as to require positive manual pressure in folding and unfolding the platform assembly with respect to the support unit.
