290HC Mast Section How to Prevent Machine Sliding Hook
The tower hook often occurs during the lifting process. The heavy objects in the air suddenly fall down, causing damage to the heavy objects themselves and to people and things on the ground.
There are many reasons for sliding hooks. Common reasons include electrical line failures, overweight suspensions, debris between friction sheets of electromagnetic clutches, and friction sheets of electromagnetic clutches that burn, stretch, and warp, making electromagnetic clutches less than rated. Torque transmission capabilities these reasons.
After the tower hook appears, the tower crane driver must remain calm and contact the signal worker to quickly disperse the ground personnel. According to the operating rules and regulations, the weight will be placed in the unmanned area on the scene by means of hooks, turning arms, and small cars.
How to prevent the tower from sliding hooks, we must pay attention to the following four matters:
1. Before and after the operation of the tower crane, the machinery must be carefully inspected;
2. Conduct occasional inspections of various lines and connection points of the tower crane electrical system, and timely repair and replacement problems;
3. Regularly check whether the brake pads of each brake are normal;
4. The tower crane maintenance personnel should be responsible for the work and do a good job in the inspection and trial operation of the tower crane.
