[0031] Specifically, a hoist connector 11 is fixed to the main hanger 1 , one end of the hoist connector 11 is connected to the main hanger 1 by bolts, and the other end of the hoist connector 11 is connected to the lifting equipment by bolts.

[0032] Specifically, there are four pulley blocks 2 , which are respectively fixed at four edges of the main hanger 1 .

[0033] Corresponding to the pulley block 2 , the number of the steel wire ropes 3 is four, and the four steel wire ropes 3 are respectively fixed to the four corners of the sling 6 .

[0034] Specifically, the counterweight assembly 4 includes a counterweight pulley 41, a support shaft 42, a counterweight block 43, and a locking block 44. The counterweight pulley 41 is detachably mounted on the end of the support shaft 42. A plurality of counterweight blocks 43 are sleeved on the support shaft 42. The locking block 44 is detachably connected to the support shaft 42 and abuts against the counterweight block 43, so as to limit the movement of the counterweight block 43 relative to the support shaft 42. In actual use, the number of the counterweight blocks 43 can be increased or decreased according to demand to achieve the best effect and ensure the stability of the suspended object.

[0035] Furthermore, the counterweight assembly 4 further includes a rolling bearing 45, the rolling bearing 45 having a first portion and a second portion that can rotate relative to each other, the first portion being connected to the support shaft 42, and the counterweight pulley 41 being sleeved on the second portion.

[0036] Furthermore, the brake assembly 5 includes a mounting seat 51, a driving member 52, a fixing member 53 and a movable member 54. The mounting seat 51 is fixed to the main hanger 1, the driving member 52 and the fixing member 53 are fixed on the mounting seat 51, and the movable member 54 is fixed to the movable end of the driving member 52. The movable end of the driving member 52 drives the movable member 54 to reciprocate relative to the fixing member 53, so that the fixing member 53 and the movable member 54 have a clamping state of clamping the wire rope 3 and a releasing state of releasing the wire rope 3.

[0037] Furthermore, the brake assembly 5 further includes a return spring 55, one end of which is fixed to the mounting seat 51, and the other end of which is fixed to the movable member 54. The return spring 55 can help the movable member 54 to return quickly.

The traction electromagnet is connected to the electromagnetic push rod through a pin shaft. When the traction electromagnet is attracted, the electromagnetic push rod is driven to move horizontally to the left. The reset spring 55 is connected to the electromagnetic push rod. At this time, the reset spring 55 is in a stretched state. At this time, the steel wire rope 3 is compressed, and the counterweight assembly 4 cannot pull the steel wire rope 3, achieving a braking effect. After the traction electromagnet is attracted for a period of time, it is released. At this time, the reset spring 55 drives the electromagnetic push rod to reset, and the steel wire rope 3 is in a free state. The counterweight assembly 4 pulls the sling 6 through the steel wire rope 3 to stabilize its state. By controlling the braking and release of the brake assembly 5, an intermittent pulling of the sling 6 is achieved to achieve its stability without deflection.
