  Daily maintenance tips for lifting chains

  The lifting chain is a very important spare part in the lifting hoist. Today, we will introduce some daily maintenance tips for it:

  1. If the product is too long or stretched after use, making it difficult to adjust, the chain links can be removed depending on the situation, but they must be even.

  2. The chain link should pass through the back of the chain, with the locking plate inserted outside and the opening of the locking plate facing in the opposite direction of rotation.

  3. The tightness of the chain is about 2% -3% of the center distance between the two sprockets when lifted or pressed down from the middle of the chain. The tightness should be appropriate. If it is too tight, it will increase power consumption and make the bearings prone to wear and tear; Loose chains are prone to jumping and falling off.

  After severe wear of the sprocket, both the new sprocket and the new chain should be replaced to ensure good engagement. You cannot simply replace the new chain or sprocket separately.

  5. Remember to add lubricating oil in a timely manner during work.

  6. The old lifting chain cannot be mixed with some new chains, otherwise it is easy to cause impact and break the chain during transmission.

  What are the reasons that can cause the lifting chain to break?

  The lifting chain can be used in conjunction with lifting slings and is an important lifting accessory with a high frequency of use. During use, it may break, and there are many reasons that can cause it to break. The main reasons are as follows:

  1、 The quality of the product itself has defects or problems, such as brittle materials, weak welding, and severe wear, which are all reasons for the easy breakage of the lifting chain.

  2、 Poor manufacturing process: Poor operation during welding and heat treatment is a significant cause of chain breakage alone. Due to substandard manufacturing quality and materials, single links in the lifting chain may experience brittle fracture or plastic deformation fracture accidents during use.

  3、 Inadequate maintenance and repair: for example, the chain rusted due to not being placed in a dry and ventilated place, rusted due to not adding lubricating oil in a timely manner, and did not pay attention to inspection before use.

  4、 The use does not meet safety requirements: for example, the chain may be too tight or too loose, overloaded lifting, the chain may jump out of the groove, or it may break due to sudden pulling.

  5、 The chain of the lifting chain falls into the iron object: it is easy to twist the chain, causing chain breakage.
