Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. SUBSTANCE: proposed device contains induction motor rotating relative to vertical axis whose stator part is rigidly secured on shaft resting through step bearing on suspended shackle coupled through adapter ring with crane hook. Rotor part supplied through flexible cable and sliprings s secured in housing resting on shaft through antifriction bearings. Outlet end of shaft is made in form of closed loop for suspending the load. Additional induction motor is installed on shaft for rotation opposite to rotation of first induction motor. Two pairs of metal rods are rigidly secured on housings of induction motors relatively perpendicular in horizontal plane. Weights are mounted on rods to travel. Load angular displacement sensor is connected through microprocessor control unit with induction motors. EFFECT: automatic control of load balancing on tower crane wire rope. 3 dwg
