A panel hoist for raising sheet or panel materials such as sheet rock, plywood, rock lath and similar materials. The panel hoist is used to aid in installation of these panels, particularly when the installer is working singlehandedly. The panel hoist includes a telescoping mast assembly, preferably having three stage operation. A collapsible base framework is provided with casters so that the panel hoist can be rolled into position. The collapsible base framework is specially constructed so as to minimize the size of the unit in the collapsed. Two different head assemblies are provided, depending upon whether panels are being installed horizontally or upright. The head assemblies are also collapsible to provide compactness and easy portability.
