auses and effects of rotation of semi-enclosed hook group
Semi-closedhook group must be paid attention to when rotating:
1. The larger the crane, the higher the lifting height, that is, the longer the wire rope between the top pulley group of the crane and the hook, the greater the possibility of the hook rotating;
2. The hook wire rope is wound into an odd match ratio and even match, and it is easy to rotate the hook. The number of wire ropes that are passed through is less, and the greater the possibility of the hook rotating;
3. The larger the weight a single wire rope bears, the greater the possibility of the semi-closedhook group is rotated;
4. The smaller the shape and size of the semi-enclosed hook group and the smaller the pulley size. The greater the possibility of the hook rotating;
5. The speed of the lifting and landing hook of the crane is unstable, especially when heavy objects are off the ground, the possibility of the hook rotating increases.
The rotation of the semi-closed hook group usually occurs during equipment lifting operations, affecting crane lifting. When lifting machinery lifts heavy objects, the hook rotates and passes through the wire rope between the hook and the ceiling pulley set of the boom. The lifted heavy objects also rotate with the hook, and cannot inherit the lifted heavy objects or put down. The rotation of the hook will affect the normal progress of lifting operations and seriously threaten the safety of the operators and equipment, so rotation must be avoided.
To sum up, the knowledge shared by the semi-enclosed hook set manufacturer and everyone, I hope it can help you.
