Abstract
Extendable bridging bar frame members are pivotally mounted to an angularly adjustable loading platform level of a bi-elevational platform lift apparatus. The bridging bar frame members are selectively extendable to engage an associated dock side loading surface in order to suspend a free end non-attached portion of the loading platform at dock side level while the opposite end portion of the loading platform is adjusted for alignment with a vertically offset dock side. This will allow angular adjustment of the loading platform level while still utilizing the mechanical support of the bridging bar frame members.
