Convert any ladder to a hoist by adding one of our three available Hoisting Wheels. Each model features a 12″ aluminum wheel, bronze bushings and a sturdy all-steel frame. Hoisting Wheels accommodate both 3/4″ and 1″ manila rope. Hoisting wheels offer great flexibility and safety when loading equipment to a rooftop. These ladder-mounted hoisting wheels are designed to remain stable by latching onto any two rungs of a ladder in a fashion the prevents swaying or wobbling. Because the handle is 24″ away from the ladder mount point the extra clearance allows for bigger and bulkier lifts. Use with 3/4″ rope only. These wheels are constructed in the U.S.A.
