Abstract
A portable lifting device is provided that includes a pair of telescoping parallel beam assemblies attached on either end to a pair of stanchion assemblies. Each stanchion assembly includes a top and bottom member as well as at least one vertical member. The bottom member of each beam assembly rests on a deck support member, and the height of each vertical member may be adjustable. A sliding guide assembly is slidably mounted on the parallel beam assemblies and includes a cross-member between the parallel beams that acts as the connection point for a lifting medium. This allows for a higher support point for the lifting medium than would be provided by a conventional single-beam device.
