ABSTRACT:
Disclosed is a hoist trolley having a pair of jacking plates with apertures for attaching the plates to a compressor. Fixed to the opposing ends of the jack-plates are telescopic legs with extendable retractable wheels and a screw jack that is used to elevate the load, once the plates are attached, enabling the wheels to be extended. Once extended, the jack base plate is raised with the wheels supporting the load. Transporting the load is accomplished by providing a pair of rails cantilevered from a stand. Also provides are additional elements to enhance the range of applications for the compressor trolley including a pry bar incorporating a motive member whereby the bar can be used in the similar function of supporting some part of the load while moving to a workspace and a depending pivot arm having one element of a fastener, with the other incorporated into an opposing jacking plate. Furthermore, the spaced apart trolley rails can include integral rollers.
