Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a fixing component used for cranes. Background Art

[0002] Lifting equipment starts a vertical or vertical and horizontal working stroke after taking the material, unloads after reaching the destination, and then travels empty to the material taking location to complete a working cycle, and then performs a second lifting or transportation. Lifting machinery can also be called lifting equipment. It is an important tool and equipment for industrial, transportation, and construction enterprises to realize the mechanization and automation of the production process, reduce heavy physical labor, and improve labor productivity. my country already has a large number of various lifting equipment. Although the number of lifting equipment used in university laboratories is small and the lifting tonnage is not large, due to the low frequency of use of lifting equipment, its maintenance and safe operation are more important. Lifting equipment is a handling machinery that lifts, lowers, and moves materials horizontally in an intermittent operation mode. The operation of lifting equipment usually has the nature of repeated cycles. With the development of science and technology and production, lifting equipment is constantly being improved and developed. Advanced electrical, optical, and computer technologies are applied to lifting equipment. Its trend is to increase the degree of automation, improve work efficiency and performance, and make the operation simpler, labor-saving, safer and more reliable. The existing gantry cranes on the market mainly use electric hoists to use hooks on the overall frame to lift and move goods. When in use, the staff hangs the hook on the goods to be lifted. It is easy to be careless when manually stepping on the hook, causing the goods to fall. The safety performance is low when loading and unloading goods, the operation process is cumbersome, the manual labor intensity is high, and the work efficiency is low. In addition, when the lifted goods are too large, the center of gravity is easy to shift. There is only a hook for support, and the goods are very likely to swing when lifted. The stability is poor and the risk is high. Utility Model Content
