In order to improve the operation of the drives of the lifting mechanisms, their designs with a partial stop of the brake massive disk when the braking process of the main work process is not required are known and profitable. This leads to some energy savings for the lifting mechanisms during the lifting of loads and their necessary stops with the necessary braking. Such processes of operation of cargo winches and some cranes are known from scientific works abroad. But there, the friction of the intermediate elements that jam the half-couplings is used to connect the kinematic chain. The main disadvantage of such structures is the possibility of slipping in kinematic working pairs, which leads to a decrease in the reliability and service life of the coupling. We have developed a new part of the drive with the use of a ball overrunning clutch that connects the kinematic chain due to engagement. The conducted studies of the proposed clutch convincingly confirmed that the developed ball overrunning safety clutches can be effectively used as devices for limiting the magnitude of the rotational moment in mechanical drives of machine building.
