Application of the technology in electric hoist hook

electric hoist trolley hook is a hook hoisting machinery in the most common. By electric hoistand pulley block part is hung on the hoisting mechanism of the wire rope or chain.According to the shape is divided into single and double hook hook, according to the manufacturing method for forging and laminated. three phase electric hoist hook is made of gold, steel, heat treated, chain, annealing, surface anti-corrosiontreatment produced, we understand in detail the application of the technology in electric hoist hook.

Electric hoist single hook has the advantages of simple manufacture, convenient use,but the stress condition is not good, mostly in the weight for the workplace 80 tons; big lifting weight often use force symmetrical double hook. Laminated hook which is composed of a plurality of cutting steel plate riveted together, the hook will not damage the cracks of individual plates, security is better, but the large self weight,mostly used in large capacity or the lifting of the molten steel ladle crane. The hook is often affected by the impact during the operation, the good toughness of high quality carbon steel manufacturing.

Mainly because of cheap wire rope hoist  in the use process, there are rarely have an overload situation. In this case, there will be deformation of the hook. And hook groupgeneral in the hanging point, is not easy to detect, if there are serious consequences.The hook is very easy to see the visual hook changes, minimize risk hook deformationalso continue to work. So the artificial let tensile strength hook group is different, it is necessary to.‍
