When equipment needing to be raised or lowered is too heavy for rope sets, and the expense of counterweights or powered flying is prohibitive, the best solution is a manual cable winch set. Ideal for lighting barrels and tracks, which are usually rigged between shows so speed is therefore not a consideration. Manual winch sets can even be used to raise whole lighting grids, access hatches, chandeliers and other equipment. Multiple steel wire ropes run via pulleys and terminate to a suspension barrel or the flown equipment, whilst a self-sustaining winch holds the opposite ends. Pile winding winches ensure that the multi-line flown equipment rises perfectly level, although standard winches are most common, and either type may be clewed to a greater number of suspension lines depending on the winch location.
