The hook of the hoist crane has the advantages of ensuring safety and avoiding accidents.

Description

technical field [0001] The invention belongs to the technical field of lifting facilities, and in particular relates to a hook of a hoist. Background technique [0002] As is well known in the industry, for a hoist, no matter it is manual or electric, it must be equipped with a hook for lifting heavy objects. figure 1 Shows the hook of the lifting hoist commonly used in the prior art, which includes a hook body 1, a cylinder body 2 and a pin shaft 3, the hook body 1 is fixed on the lower part of the cylinder body 2 with a nut, and the pin shaft 3 is arranged on the cylinder body Near the middle of body 2. When the suspension hook of this structure is to be configured on the lifting hoist, then, as long as one end of the rope such as a steel wire rope is fixed with the bearing pin 3, the middle part of the rope is wound on the winch of the lifting hoist, and the other end of the rope is One end can be fixed with the winch. In the state of use, the hook body 1 pulls up or h...

Problems solved by technology

[0003] However, in the actual use process, there are often two lifting situations. One is that the operator does not estimate the quality (weight) of the object to be hoisted enough, which leads to extreme accidents that should not occur due to overloading of the hoist. The lifting hoist and the objects being hoisted will be damaged, and the serious one will pose a threat to personal safety; the second is the overload hoisting caused by the operator's subjective reasons, which is specifically manifested as rushing for time and progress, which will also cause the aforementioned adverse consequences
