　　Crane hook group is a common spreader in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism by means of pulley sets and other components. The hooks are divided into single hooks and double hooks according to their shape; they are divided into forged hooks and stacked hooks according to their manufacturing method.

　　Composition and wear standards of hook group

　　Hook group is a more commonly used picking device in lifting machinery and is one of the important lifting equipment in lifting machinery, so its quality requirements are very high. There are two common hook types, namely single hooks and double hooks. Let’s introduce their material requirements below.

　　Single hook is a commonly used hook. It is simple to construct and easy to use.

　　Single hooks have a form:

　　The threaded straight handle single hook is connected to the single hook with a ring, and the threaded part is connected to the hanger, and the ring is used to directly connect to the wire rope.

　　Double hooks are symmetrical under force, and the hook body material is fully utilized, but it is not as convenient as single hooks.

　The structural dimensions of hooks have been standardized. In general, it can be directly selected according to the relevant standards according to the size of lifting weight and the type of work (manpower or maneuver).

　　Once the hook breaks during use, it is very easy to cause accidents. Therefore, when using it, it must be used strictly in accordance with regulations and must not be used overloaded. Hooks without load marks on the pair should not be used casually.

　　Hook scrapping standards:

　　Regularly inspected hooks, and should be scrapped in time when the following conditions are met:

　　(1) If there are cracks, breaks or cracks on the surface, they should be scrapped;

　　(2) If the wear of hazardous sections exceeds 10% of the original size, they should be scrapped;

　　(3) If there are plastic deformations on the hazardous sections and hook necks, they should be scrapped;

　　(4) If the opening degree increases by 15% compared to the original size, they should be scrapped;

　　(5) If the twisting deformation of the hook tip exceeds 10%, they should be scrapped.

　　The specific use and inspection methods for correct use of hook sets

　　In the process of using hook sets, professional operators need to be operated, and from installation to use, they need to be carried out in accordance with the specifications. So do you know how to correctly use the fully enclosed hook set? Let me introduce it in detail below:

　　1. Before using hook sets, be sure to ensure that they are produced by a regular manufacturer and have a certificate of qualification. Do not blindly put into use, and conduct stricter inspections on various indicators such as opening degree, weighing weight;

　　2. Check that the rated lifting weight marked on the hook must not be less than the actual lifting weight. If there is no marking or the lifting weight mark is unclear, the rated lifting should be recalculated and determined through a compliance test to determine its loading by complying with the test3. The hooks specially used for lifting machinery have higher requirements. It is necessary to ensure that their surface must be smooth and there must be no defects such as peeling, markings, acute angles, seams and cracks; 4. Use tinder oil to clean the three dangerous sections of the hook and use a magnifying glass to see if there are any cracks. For plate hooks, wear and tear of the sleeves and pins; 5. Pay attention to observation and inspection during the etching process during the use of the hook group, check whether there are any hidden dangers such as deformation, cracks, cross-sections, etc., and do not have overweight behavior to avoid shortening the service life of the fully enclosed hook group.
