Since 1954, Wallace Cranes has manufactured portable and adjustable gantry cranes at its Malvern, Pennsylvania facility, along with other engineered lifting equipment for industrial applications. As the original patent holder of the Thrifty and Tri-Adjustable gantry designs, the company is known for cranes built around a distinctive pinned-joint system that makes them portable and straightforward to assemble. Wallace builds its equipment in the United States using U.S.-sourced steel, and says more of its gantries remain in use than those of any other manufacturer.
