Abstract
Apparatus for limiting the amount of force applied to a cable of a hoist by applying a force on clutch plates which are operatively joined to rotatable plates so that there is relative rotation between the clutch plates and the rotatable place when a force, equivalent to that placed on the clutch plates, is placed on the load supporting end of the cable. Also, two fall arresting devices are provided.
