Our heavy-duty trolley system uses 6″ aluminum I-beam for a track and can accommodate hundreds of pounds of load. The trolleys come in 12, 24, and 36 inch lengths. Each trolley includes a mounting surface with dozens of grid-spaced threaded holes. This allows the trolley to carry virtually anything.
About Selecting a Trolley
Working Load Limits – is the maximum load these blocks are designed to hold provided that the load is not people or that the load is not lifted over people. This rating is one fifth of the ultimate strength.
Safe Working Load – is the maximum load these blocks are designed to hold when lifting people or lifting over people. This value is half of the Working Load Limit and one tenth of the ultimate strength.
