The lifting hook is an important component in the lifting machinery. Its common problems and solutions are as follows:

FAQ

Hook damaged and broken:

During use, the hook may crack, deform or even break due to friction and overload. Under long-term working conditions with high intensity and frequency, the bottom diameter of the thread and the empty slot at the tail of the hook are prone to cracks due to stress concentration.

The wear and tear of the hook opening and dangerous sections and long-term use will weaken the strength of the hook and easily cause the hook to deform or break.

Collision damage:

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

Wear issues:

The hook mouth of the hook set will gradually wear out as the use time increases. If not treated in time, its load-bearing capacity and safety will be seriously affected.

Solution

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 tilting, speeding, etc.

Regular inspection and maintenance:

Establish a regular inspection system to conduct detailed inspections of all parts of the hook group to discover and deal with potential problems in a timely manner.

Pay attention to the opening of the hook and the wear of critical sections, and anneal the hook regularly.

Once cracks are found, they should be scrapped according to relevant standards, and welding repairs on the hooks are strictly prohibited.

Strengthen lubrication and maintenance:

Regularly add an appropriate amount of grease to the lubrication points and hinge points of the hook set to reduce friction and wear and maintain its good operating condition.

Strictly control overload usage:

Clear the rated load capacity of the crane, and overload operations are strictly prohibited.

Optimize the usage environment:

For hooks used in metallurgical environments, when the thermal radiation temperature exceeds a certain limit, methods to isolate the thermal radiation should be adopted.

Common problems with lifting hooks are closely related to the working environment, operation methods and maintenance management. Through standardized operations, regular inspections, strengthened lubrication and maintenance, strict control of overload use and optimization of the use environment, the failure rate of the hook can be reduced and the safe operation of the lifting machinery can be ensured.
