Hook Safety Is High Aug 22, 2017

Hook with the national standard -JB / T4207.1-1999, the use of safe and reliable, pulley materials used cast iron, cast iron wheel with excellent wear resistance, reliable toughness and impact resistance, Lifting Hooks pulley core with powder metallurgy oil sleeve , Not only the pulley has a flexible operation, strong, wear-resistant advantages, but also improve the product life.

Hooks are a kind of take-up device, which is a very important handling method for the crane. It can safely and efficiently assist the crane to operate, Lifting Hooks and can save time and reduce the cost.

Hooks are extremely broad, generally include: shackles, rings, rings, pear rings, long rings, combination rings, S hooks, nose hooks, American hooks hooks, eye hooks, with insurance card rings Screws, chain shackles, with a unique, innovative, high quality, safe features.

Hooks are the most common spreader in lifting machinery. Hooks are often suspended from the rope of the hoisting mechanism by means of components such as pulley blocks.

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, Lifting Hooks the hook must be strictly controlled material, inspection and scrapping standards.


Hook materials must be made of 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, but the force is not good, mostly used in the weight of 80 tons of the following workplace; from the weight often used symmetrical double hook. Lifting Hooks The laminated hooks are made of a plurality of steel plates which are cut and shaped, and the whole hooks are not damaged when the individual plates are cracked. The safety is better, but the weight is large, mostly used in heavy lifting or lifting On the crane. Hooks are often impacted during operation and are made of high quality carbon steel with good toughness.
