Do you know what issues need to be paid attention to when using hooks?
The hook is a kind of suspension device suspended on the wire rope of the lifting mechanism by means of pulley sets and other components. It often connects the lifting mechanism of the crane and the required transported items. Widely used in factories, mining, petroleum, chemical industry and ship terminal industries.
Common categories: There are many types of hooks, which can be divided into two categories according to their shape. The lifting weight ranges from 5 tons to 150 tons, and the specific number is that a single hook is used below 80 tons. When the lifting weight is large, a double hook with a symmetrical force is used.
Structural composition: The hook group is generally composed of hooks, hook beams, thrust bearings, hook nuts, pulleys, pulley shafts, pulley plates and pulley covers.
Processing technology: Strictly in accordance with national standards, No. 20 carbon steel with good toughness is generally used as raw material, and is made of hot forging, welding, heat treatment, and tempering. It has a beautiful shape and reliable quality.
Product advantages:
1. Durable: Good materials and good quality, 13 years of industry experience, mature and reliable technology.
2. Simple operation: simple installation, easy operation and maintenance,
3. Flexible and safe: The hook rotates flexibly within the horizontal direction 360 and vertical direction 180, the product has high tensile strength, small yield and strength ratio, and is safe and reliable.
4. Support customization: high production accuracy, solve customer needs problems
1. Acceptance:
(1) The surface of the hook should be smooth and free of defects such as peeling, acute angles, burrs, seams, etc.
(2) The hook group needs to be flexible to rotate, and the positioning bolts, opening pins, etc. of the fixing nuts must be tightened intact.
(3) Verify the manufacturer's technical certificate and measure and inspect the opening degree of the hook.
2. Precautions:
1. The new hook should undergo load test.
2. Check the hook connection part regularly to confirm whether the connection is reliable and whether the lubrication is good.
3. The hook shall not perform overload operations.
4. If the surface of the hook appears, the thread is corroded, the dangerous section or the neck is deformed, it should be replaced as soon as possible.
5. The wear of the dangerous section of the hook reaches 10%, and the opening degree increases by 15% compared with the original size; if the hook body twists and deformation exceeds 10°, it should be scrapped.
