The spinner replicates the mechanical forces from many from rotating systems like sheaves, pulleys, belts, and cables. Spinner demos are self-contained in a handheld portable box and designed and built to be used over many training sessions. This demonstration requires the use of a hand-held cordless drill (not included).
