　　Holding hooks are important components in lifting machinery. The common problems and solutions are as follows:

　　Frequently asked questions

　　The hooks are damaged and broken:

　　Discovery, deformation and even breaking due to friction and overloading during use. In a long-term working state with high strength and high frequency, the thread base diameter and hollow cutter groove of the hook tail are prone to cracks due to stress concentration.

　　Wear of hook openings and dangerous sections, long-term use will lead to weakening of the hook strength, which may easily cause the hook to deform or break.

　　Collective damage:

　　In complex operating environments, if the hook group fails to accurately rise to a safe height or the driving trajectory is unstable, it is prone to collision with other objects, resulting in serious damage such as broken wheel rims.

　　Wear problem:

　　The hook part of the hook group will gradually wear with the increase of use time. If it is not handled in time, it will seriously affect its load-bearing capacity and safety.

　　Solutions

　　Standard operating behavior:

　　Strengthen the training and management of crane operators to ensure that they strictly abide by operating procedures and avoid improper behaviors such as crooked pulling and inclined lifting and speeding.

　　Regular inspection and maintenance:

　　Establish a regular inspection system to conduct detailed inspections of various parts of the hook group, and promptly discover and deal with potential problems.

　　Pay attention to the opening degree of the hook and the wear condition of critical sections, and anneale the hook regularly.

　　Once cracks are found, they should be scrapped according to relevant standards, and it is strictly forbidden to weld and repair the hook.

　　Intensify lubrication maintenance:

　　Regular grease is added to the lubrication points and hinge points of the hook group regularly to reduce friction and wear and maintain its good operating condition.

　　Strictly control overload use:

　　Clarify the rated load-bearing capacity of the crane and strictly prohibit overload operations.

　　Optimized use environment:

　　For hooks used in metallurgical environments, when the thermal radiation temperature exceeds a certain limit, the method of isolating thermal radiation should be adopted.

　　Frequently asked questions about lifting hooks are closely related to the working environment, operating methods and maintenance management. Through measures such as standardizing operation, regular inspections, strengthening lubrication and maintenance, strictly controlling overload use and optimizing the use environment, the failure rate of the hook can be reduced and the safe operation of the lifting machinery can be ensured.
