Inspection of Henan Weihua crane hook system
Crane hooks are a very important and critical part of the crane. Generally, the wear of the relevant parts of the group will be more complicated, and it will be more complicated when problems occur. Today, Henan Weihua Crane will introduce you the relevant issues.
1. If the hook part is worn, it is normal. After the heavy object is lifted, it is necessary to adjust the center by itself. Therefore, the sliding wear at the hook of the spreader is very common and inevitable.
2. If the rim of the pulley is broken, it is mainly caused by a collision. For example, the hook group does not rise to the necessary height, or the vehicle is unstable or the crane is slanted, and the swing of the weight thing causes the pulley to collide.
3. If there are not easy to defect the hidden wear risk , it should be the bottom diameter of the tail thread of the hook or the clearance groove between the thread and the rod. Cracks occur due to stress concentration. The hook nut should be removed during maintenance, and the dirt on the upper side should be cleaned and carefully checked.
Therefore, when using lifting equipment, it is necessary to carry out safe operation, and it is necessary to check the hook part regularly. Even if it is processed, the equipment can be safely operated. If you want to purchase equipment, you can contact Henan Weihua Crane.
