The invention discloses a crane stall self-locking device based on the centrifugal force principle, and relates to the technical field of cranes. The crane stall self-locking device comprises a crane base, the upper surface of the crane base is fixedly provided with a hoisting motor, the upper surface of the crane base is fixedly provided with a supporting seat, and the outer wall of the supporting seat is rotatably connected with a rotating shaft; the outer wall of the rotating shaft is fixedly sleeved with a take-up wheel, a stall box is fixedly connected to the outer wall of the supporting seat, a limiting block is fixedly connected to the outer wall of the rotating shaft, the outer wall of the limiting block is fixedly sleeved with a sleeve, and a mounting frame is fixedly connected to the outer wall of the sleeve. According to the crane stall self-locking device based on the centrifugal force principle, through cooperation of centrifugal force and electromagnetic transmission, the stall self-locking device an play a role in protecting a hoisted object by locking hoisting equipment, meanwhile, a heavy object is prevented from hurting people, the effect of protecting people and the equipment is achieved, and compared with the prior art, the stall self-locking device is higher in reliability.
