　　Hook is one of the key components of lifting machinery. It is an indispensable equipment in the transportation, construction and other industries. It is also a device with a high safety risk factor during construction.

　　The main types of crane accessories hooks

　　There are many types of hooks, and they can be divided into two categories according to their shape. According to the different manufacturing methods, the hook can be divided into die-forged hooks and laminated hooks. The die-forged hooks are made of a whole, with low cost, easy manufacturing, and more widely used. The laminated hooks are connected by multiple rolled steel plates and installed in the middle of the buffer sheet. Once the die-forged hook fails, the entire hook will be scrapped. However, for the laminated hook, even if some rolled steel plates fail, it will not cause the overall damage to the hook. Just replace a certain steel plate.

　　Precautions for safe use of crane accessories hooks

　　The hooks that are about to be put into use must be products produced by regular and professional manufacturers according to the technical conditions and safety specifications of the hooks, and must have a quality certificate; the hooks used for the first time can only be used after load tests, and the hooks must not be overloaded; during the use of the hook, it is necessary to check whether the hook is lubricated well, whether there are cracks or severe deformation, corrosion, or wear; the test should be conducted once a year. During the test, it is recommended to conduct a static test of 1.25 times the allowable workload for 10 minutes, and then use a magnifying glass or other methods to check for cracks, notches and residual deformations. If there are defects on the hook, no welding shall be made. It is recommended to replace the hook.

　　Friendly reminder: When the hook has cracks on the surface, the wear of dangerous sections reaches 10% of the original size, the torsion deformation exceeds 10 degrees, the dangerous sections and the neck of the hook are plastically deformed, and the opening degree increases by more than 15% compared with the original size, etc., it should be scrapped.

　　The hook is strictly in accordance with national standards, and uses No. 20 carbon steel with good toughness as raw material, and is refined through hot forging, welding, heat treatment, tempering and other processes. It has beautiful shape and reliable quality; it is simple to install and is easy to operate and repair; the hook rotates flexibly within the horizontal direction 360 and vertical direction 180, the product has high tensile strength, small yield and strength ratio, and reliable quality.
