Many well-known lifting hooks and wire ropes are slings and are widely used in the operation of various lifting equipment. From the perspective of the structure of the lifting equipment, the two ends of the wire rope are hung on the towing hook. Due to the frequent lifting and transportation, the wire rope will increase the wear on the vertical dangerous section of the hook. Especially when the load is large and the road surface is in bad condition, the wear of the hook and the wire rope is more serious. How to effectively slow down the wear between the hook and the wire rope? Let me introduce to you the following slings.
1. Take a wire rope with a long length, and use rope clips at both ends to secure the main wire, so that the contact between the hook and the wire rope changes from one to three. By increasing the contact area between the hook and the wire rope, the friction and wear between the two are reduced, and the service life of the hook and the wire rope is effectively prolonged.
2. Other materials can be used to replace the wire rope. If the nylon rope or nylon
Sling used on ocean ships is used instead of the steel wire rope, the effect is also very good. In addition, it is recommended that the length l of the wire rope of the locking hook used is 1.35-1.45m. After many tests, it is known that if the wire rope is too long, the hook will be hung high, which will affect the driver's vision; if the wire rope is too short, it will be inconvenient to hook, and the waist and wrist of the hooker will be easily sprained. Generally speaking, the height of the driver takes a larger value, and vice versa, a smaller value. Such operation is convenient, and can take into account the needs of the driver's field of vision.
3. You can also take a long steel pipe and put it on the wire rope according to the shape of the wire rope. The steel pipe is in contact with the surface of the hook, so that the wire rope does not directly contact the hook, so it can protect the hook and the wire rope from being seriously worn. The casing can also be made of other materials, such as thick rubber pipes, high-pressure hoses with steel mesh, etc.
Before working on the lifting equipment, it is necessary to carefully check whether all the lifting parts are normal; the weight of the objects to be lifted must be correctly grasped, and overloading is not allowed; the lifting lugs must be strictly checked, and the rope buckles should be tied above the center of gravity of the heavy objects And bind firmly; when the lifting heavy object has a sharp angle, padding should be added before the rope buckle; the lifting heavy object should be tied with a sliding rope; it is necessary to check whether the force position and the force situation meet the requirements.
The above contents are claimed and hoped that the users of the lifting equipment should pay special attention. We should pay close attention to and check whether the lifting equipment is worn, whether the wear is serious, and the wear and tear should be replaced in time. Safe operation is more important than anything else! For more information on slings please call.
