OVERLOAD PROTECTION, DRIVE TRAIN COMPRISING SUCH AN OVERLOAD PROTECTION, DEVICE COMPRISING A LIFTING TOOL, AND METHOD FOR APPLYING WORKING FORCES

摘要

An overload protector has an input element, an output element juxtaposed with the input element, and a clamping plate. Fasteners fix the clamping plate to one of the elements against relative movement. A coupling between the clamping plate and the other of the elements permits only limited relative movement of the elements through a stroke having a predetermined length in a predetermined direction. A connector between the clamping plate and the other element fixes the clamping plate and the other element together against relative movement until an overload force greater than a predetermined critical limit is exerted shifting either of the elements toward or away from the other element in the predetermined direction.
