In order to better realize the locking of the crane hook, the first motor is preferably a speed reducing motor.
Preferably, the second motor is a brake motor.
Preferably, the top wall of the stringing hole is provided with a limiting groove.
Preferably, the position of the rope through hole and the top end of the hook are positioned on the same vertical line.
Has the advantages that: according to the invention, the rotation mechanism of the lifting hook is improved to be driven by the worm gear and the worm, the fine adjustment of the rotation angle of the lifting hook with large load is realized by utilizing the differential characteristic of the worm gear and the worm, and after the adjustment is completed, the self-locking of the lifting hook is realized due to the reverse locking effect of the worm, so that the accident caused by the wrong rotation and out-of-control of the lifting hook is avoided, and the convenience and the safety of the engineering are effectively improved.
