What is a Lifting Chain?

Definition of lifting chain 

The essential and important material pick-up device of the crane can adjust the length of the chain according to the lifting height of the lifting object, which plays an important role in improving the working efficiency of the crane and expanding the working range of the crane.

The role of lifting chain

In the production of lifting products, whether it is a chain electric hoist or a lifting chain, quality and efficiency are emphasized in production. The chain is a lifting device composed of a chain ring. It is easy to bend and easy to use. It is widely used in cranes and electric hoists and is one of the common lifting slings. The hoisting chain can also be combined with a hook, a shackle, etc. to form a hoisting sling.

Material and specifications of lifting chain 

The G80 lifting chain is an indispensable lifting device for lifting heavy objects. It is made of high-grade alloy steel (manganese steel, etc.) from Germany's advanced assembly line equipment. The whole process is strictly controlled, and the lifting chain can reach 80. Level international standard.

One type of hoisting chain is usually a circular chain, which is commonly known as a circular chain. The 60th, 80th, and 100th lifting chains refer to the strength level of the circular chain. Polishing, blackening, dipping, painting, hanging plastic, hot dip galvanizing, electroplating, Dacromet refers to the surface treatment process of the chain. The strength level of the hoisting chain determines the load bearing capacity and service life of the chain. The strength level of the chain is determined by the materials used and the manufacturing process. The materials used for the lifting chain are generally 20MoSi, 20Mn2, 25MnV, 23MnNimocr54. 20MoSi can only be used as a chain of 60 or less; 20Mn2 can also be used to make some small-diameter 80-level chains with relatively advanced technology. Generally, small factories cannot reach this. Requirements; 25MnV material is more commonly used in the 80-level chain, but the 80-level is also the ultimate, generally the largest will be 20mm diameter; 23MnNimocr54 material to do 80-level chain should be said that just started, can achieve 100-level circular chain . Generally speaking, the specifications 6*18, 8*24, 10*30, and 12*42 refer to the chain diameter and outer length of the chain ring.


Considerations of lifting chain

1. The tightness of the lifting chain should be appropriate. If it is too tight, it will accelerate the wear and tear, resulting in excessive power consumption. If it is too loose, it will be prone to de-chaining.

2. Be sure to do the lubrication of the part. When lubricating, not only for the chain, but also the lubrication of the gap between the roller and the inner sleeve, reducing wear and maximizing the working conditions;

3. If the chain is too long, or there is elongation after use, we need to remove the excess number of chain links according to the actual _, but must be even;

4. If the sprocket wears out seriously, we not only replace the new sprocket, but also replace the new chain. If only a single part is replaced, it will lead to the two parts not meshing well and accelerate their wear.

How to choose to buy

1. Before purchasing a safe lifting chain, we must first confirm the qualification of this company. Is it a well-known company in the country, and what is the qualification? How about user word of mouth?

2. Why can the company provide a high-performance and high-quality lifting chain to users? It is necessary to confirm the resources of the company, whether it has strong technical support, and generally can operate stably for more than ten years.

3. Product performance, stable performance, used customers with a renewal rate of 95% or more, product performance is certainly not bad!

4. Product price is transparent, no random charges, good fear is too expensive, cheap and afraid of bad, so we must weigh the cost-effectiveness of the product, the same configuration, the same performance, basically the price will play a decisive role.
