Hook is a kind of spreader suspended from the wire rope of the hoisting mechanism with the help of pulleys and other components. It is often used as a connection between the lifting mechanism of the crane and the items to be transported. It is widely used in factories, mines, petroleum, chemical industry, ship terminals and other industries.

Common classification: There are many types of hooks, which can be divided into two categories: single hook and double hook according to their shape. The lifting capacity ranges from 5 tons to 150 tons. Specifically, a single hook is used when the load is below 80 tons. When the lifting capacity is larger, a double hook with symmetrical force is used.

Structural composition: The hook group generally consists of hooks, hook beams, thrust bearings, hook nuts, pulleys, pulley shafts, pull plates and pulley covers.

Processing technology: Strictly in accordance with national standards, generally using No. 20 carbon steel with good toughness as raw material, it is made through hot forging, welding, heat treatment, tempering and other processes. It has beautiful appearance and reliable quality.

Product advantages:

1. Durable: good materials, 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 can flexibly rotate within 360 degrees in the horizontal direction and 180 degrees in the vertical direction. The product has high tensile strength, small yield-to-strength ratio, and safe and reliable quality.

4. Support customization: high production precision to solve customer needs

1. Acceptance:

(1) The surface of the hook should be smooth and clean, without defects such as peeling, sharp corners, burrs, and seams

(2) The hook group needs to be flexible in rotation, and the positioning bolts, cotter pins, etc. of the fixing nut must be tightened completely.

(3) Verify the manufacturer’s technical certification documents and measure and inspect the hook opening.

2. Things to note:

1. New hooks should undergo a 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 must not be used for overload operations.

4. If there are cracks on the surface of the hook, thread corrosion, dangerous section or neck deformation, it should be replaced as soon as possible.

5. The dangerous section area of the hook is worn up to 10%, and the opening is increased by 15% compared to the original size; when the torsional deformation of the hook body exceeds 10°, it should be scrapped.
