The output shaft end of the first motor 17 is connected to the rotating shaft where the driving drum 16 is located through a coupling. Fixed pulleys 18 are installed on both sides of the top end of the frame 5 through brackets. Hooks 19 are fixedly provided on both sides of one end of the top of the carrying plate 8. The driving drum 16, the fixed pulley 18 and the hook 19 are connected by a traction rope.

[0027] Through the above scheme, the main function of the hoist is to lift materials by using the lifting mechanism;

[0028] In this embodiment, preferably, a screw rod 20 is movably provided at one end of the top of the supporting plate 8 through a rotating shaft, and a threaded cylinder 21 is movably sleeved on the outer side of the top end of the screw rod 20;
