[0002] The existing publication number is CN220766249U, which discloses a construction hoist, comprising a transverse frame, one side of the transverse frame is fixedly connected with an adapter block, the top of the adapter block is fixedly connected with a hanging ring, the inner side of the transverse frame is slidably connected with a slider, and the slider is symmetrically arranged. The inner side of the top of the slider is threadedly connected with a screw rod, and the outer side of the screw rod is movably connected with the transverse frame through a limiting hole, and the bottom of the slider is fixedly connected with a base. The steel cable used for the crane is connected to the hanging ring. When hooking a material with a longer length, the slider is slid to drive the base and the hook at the bottom of the slider to cooperate with the U-shaped limiting hole to move to a predetermined point, and the hook is used to hook the cable bundled on the outside of the material. The screw rod is rotated clockwise to limit the horizontal position of the slider, which can effectively expand the hooking and lifting points, increase the distribution of force points when lifting materials with a longer length, and effectively improve the stability of the material lifting process.

[0003] However, its adjustment range is limited, and it is inconvenient to tighten or loosen. There will be errors when comparing with the scale when adjusting the length. Utility Model Content

[0007] Preferably, a synchronization shaft is fixedly connected between the left and right cable shafts, so that the lengths of the two hooks released are the same, which is more convenient and quicker without the need for scale comparison.

[0008] Preferably, a limiting elastic safety rope is fixedly provided at the middle part of the outer end surface of the brake end disc, and one end of the limiting elastic safety rope is fixed on the double-plug pin to pull back the double-plug pin to prevent the double-plug pin from loosening relative to the pin hole.

[0009] Preferably, the maximum stretching length of the limiting elastic safety rope does not exceed the combined depth of the limiting socket and the pin hole, thereby preventing the double-plug pin from being completely pulled out of the limiting socket.

[0010] Preferably, the diameter of the pin hole is larger than the diameter of the limiting plug hole.

[0011] The advantages and positive effects of the utility model are: first, the lock of the double-plug pin on the steel cable end disc is released, and then the sling steel cable of appropriate length is pulled out and hoisted at a suitable position according to the length of the hoisted object, and then the double-plug pin is reset to lock the position of the steel cable end disc. Such a structural design can directly hoist the two hooks at both ends of the object, greatly expanding the hoisting range, increasing the balance redundancy, and effectively improving the stability.
