The Richelieu Roller Handling Trolley makes it possible to quickly and easily move heavy and awkward objects like sheet goods and I-beams. Before the tool is loaded, the trolley’s wheels stand vertically and there is a space between the jaws. Once weight is added, the center drops down and the sides tip inward to clamp the load. The unit’s low center of gravity adds to its stability. The trolley turns on a dime and has a capacity of 1,000 pounds. Price: $139. COO: Canada. 800-619-5446.
