Hooks Are Made Of High Quality Carbon Steel With Good Toughness


Hook is the main parts of lifting machinery, its material, manufacturing process, quality maintenance inspection and other aspects of the neglect of management, will directly cause the accident. Therefore, the hook must be strictly controlled material, inspection and scrapping standards.

Material

Hook material must use high-quality low-carbon killed steel or low-carbon alloy

Plate steel general application GB700-79 "ordinary carbon structural steel technical conditions" in the A3, C3 steel 16Mn steel.

Hooks are divided into single hooks and double hooks by shape. They are divided into forged hooks and laminated hooks by manufacturing method.

Single hook manufacturing is simple, easy to use, Lifting Hooks but the force is not good, mostly used in the weight of 80 tons below the workplace; from the weight often used force symmetrical double hook. The laminated hooks are made of a plurality of steel plates which are cut and formed. The individual hooks are cracked and the safety is better, Lifting Hooks but the weight is large. On the crane. Hooks are often impacted during operation and are made of high quality carbon steel with good toughness.

Lifting Hooks The laminated hooks are made of a plurality of steel plates which are cut and formed. The individual hooks are cracked and the safety is better, but the weight is large. On the crane. Hooks are often impacted during operation and are made of high quality carbon steel with good toughness.

Hooks are extremely broad, generally include: shackles, rings, rings, pear rings, long rings, combination rings, S hooks, nose hooks, American hooks horn hooks, eye hooks, with insurance card rings Screw, chain shackles, with a unique, innovative, high quality, safe features for factories, mines, petroleum, Lifting Hooks chemical and ship terminals and so on. To ensure safety, quality safety factor, static load up to 3 times. From the weight of 5 tons to 150 tons.

A hook or hook attached to a chain or rope. Another kind of coarse, usually hooked handle, especially for carrying goods or hanging meat.

Hook is one of the important parts of the crane, its use is related to the crane and the connection of heavy objects is also a guarantee of heavy lifting safety. In the daily work, Lifting Hooks in order to ensure that the crane can work safely, often need to check the hook, then the hook of the daily inspection work which?

1, lifting the use of the new hook in the use of the front waist to check, should have the manufacturer's technical documentation, or can not be blindly put into use, the opening of the new hook to be measured, should meet the requirements.

2, the new hook should do the load test.

3, the hook before use, should check the hook marked on the rated weight, Lifting Hooks not less than the actual weight. If the mark is not marked or the weight mark is blurred, it should be recalculated and determined by the test to determine its rated weight.

4, the hook three dangerous sections of the application of oil cleaning, with a magnifying glass to see if there is no crack. On the plate hook should be poor village sets, pin wear situation.

5, lifting hoisting operations used hook, the surface should be smooth, Lifting Hooks can not have stripping, nicks, acute angle, joints and cracks and other defects.

6, the connection part of the hook should always be checked to confirm whether the connection is reliable, lubrication is good.

7, hook in the use of the process, should be regularly checked, Lifting Hooks the main contents of the deformation, cracks, wear, corrosion, etc., and should be recorded.

8, hanging sling when the hanging cable hanging to the bottom of the hook. Suzhou hoisting company operations in the process of hanging hooks should be linked directly to the components of the ring, can not be hard, Lifting Hooks so as not to cause the hook body by lateral force, resulting in distortion.

9, hook is not allowed to overload operation.

10, hook can not repair welding.

11, the hook should be equipped with a safety device to prevent decoupling.

Hooks are extremely broad, generally include: shackles, rings, rings, pear rings, long rings, combination rings, S hooks, nose hooks, American hooks horn hooks, eye hooks, Lifting Hooks with insurance card rings Screws, chain shackles, with a unique, innovative, high quality, safe features. The hook is the most common type of spreader in lifting machinery. The hooks are often suspended from the rope of the hoisting mechanism by means of components such as pulley blocks.
