Abstract

The invention discloses a suspension hook for a crane, comprising a plate hook, the plate hook includes a hook body and a hook neck, and a groove is fixedly arranged on the plate hook body, and the diameter of the groove is at least 20mm. The depth is at least 20mm, the groove is integrated with the hook body of the plate hook, the groove is made of alloy, and the surface is quenched and fired; the alloy is mainly chromium, and the material of the neck of the plate hook is It is 20 high-quality carbon steel, and the hook body of the plate hook is also provided with anti-slip threads. In the present invention, a groove is provided on the hook body of the plate hook to fix the wire rope to prevent the wire rope from shaking and falling off the hook during transportation; the diameter and depth of the groove part can adapt to the size of most wire ropes on the market , and can be firmly engaged; the groove part adopts chrome alloy and surface quenching technology to improve the overall strength and surface hardness of the groove, so as to improve the wear resistance of the groove.

Description

technical field [0001] The invention relates to the technical field of mechanical accessories, in particular to a hook for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. [0003] The hook is the most common type of spreader in hoisting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of a pulley block and other components. Hooks are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgy and chemical industry, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary construction, slope tunnel, shaft treatment Protection, sea rescue, marine engineering, airport construction, bridges, aviation, aerospace, venues and other important industries and infrastructure engineering machinery and ...
