The role of lifting chain: In the production of Yu Diao lifting products, whether it is chain electric hoist or lifting chain, the production of emphasis on quality and efficiency. Chain is a lifting device made up of link ring, it has the characteristics of easy bending and convenient use, Lifting Chain it is widely used in cranes and electric hoist, and is one of the common lifting sling. Lifting chain can also be combined with hooks, shackle and other lifting sling used.
In the domestic hoisting equipment factory, Lifting Chain the general production chain is the G80 class hoisting chain, the anti-impact ability, the carrying capacity, the toughness and the elongation rate, greatly enhances its safety and the service life.
In reality, we encounter more and more problems, such as: in the lifting industry, we also have to rely on a lot of manpower to complete some lifting operations, Lifting Chain then the lifting chain can be used, for example: when the weight needs to be bundled, use it to bind. When the weight needs to ascend, it is used for lifting operations. When two machines need to be driven or towed, this can be a transmission chain between two machines. Its security is also very high, so that users do not have to worry about the safety of the problem; in the lifting industry, Lifting Chain the lifting chain can help people solve some big problems, but also can help users save a lot of human and financial resources, but also improve efficiency.
The wear of the lifting chain mainly occurs between the tip shaft and the sleeve. The intestinal turn makes the drying between the large and the chain longer, until the chain can not be exactly the same as the sprocket, or the correct fixed distance and timing. Sometimes the wear between the roller and the sleeve, Lifting Chain or between the chain plate and the guide, will also cause the lifting chain to malfunction. The lifting chain is a gradual process due to wear and tear, below to understand the lifting chain wear three stages, as follows:
The first stage is the initial running-in, the time is relatively short. The tip shaft and the point on the sleeve are worn off, and the small heart is Bojin flat.
The second stage is the coarse and slow xiao wear and tear. At this stage, Lifting Chain the tip shaft is properly formed in the sleeve, and the bearing area is adequately lubricated.
The third stage is the relatively fast end wear. This phase of lubrication may be invalid or ineffective. Or the surface of the sodium shaft and sleeve is abraded. Or the chain grows. The load of individual nodes increases dramatically. When the load exceeds the yield limit. The chain produces a plastic deformation. The chain plate, the chain plate hole is elongated, causes the chain not to work normally
