Tips for maintaining anchor chains

Anchor chains are used more and more frequently in marine ships. You should learn to properly maintain the anchor chain to increase the service life of the anchor chain. Only diligent maintenance can ensure the normal operation of cranes, ships and other machinery, so as to achieve safe operations. So, how to maintain the anchor chain daily?xRyhwMQ5S-KzF3keoB6RsQ

First of all, when using the anchor chain, you should always check to make sure that the sprocket is installed on the shaft without skew or swing. If there are related improprieties, they must be corrected in time. Check the tightness of the anchor chain at the right time and make correct adjustments in time. The tightness of the anchor chain should be appropriate. If it is too tight, it will increase power consumption and the bearings will wear out; if it is too loose, the chain will easily jump and fall off. If the anchor chain is too long or elongated after use, it is difficult to adjust, remove the chain link according to the situation, but it must be an even number. The chain link should pass through the back of the chain, the lock piece should be inserted outside, and the opening of the lock piece should face the opposite direction of rotation.

Secondly, it is necessary to check the degree of wear of the anchor chain frequently. To what extent can the anchor chain be worn out? More than 1/3 of the chain links of the same anchor chain have obvious elongation, and the deformation and wear amount to 10% of the original diameter cannot be used. After the anchor chain is severely worn, a new sprocket and a new chain should be replaced to ensure good meshing. It is not just a replacement of a new chain or a new sprocket. At the same time, the end of the anchor chain and the commonly used end should be used for a year or two, and the front and rear positions of each chain link should be changed in a planned way, and the mark should be re-marked. In addition, special attention should be paid to that the old chain of the anchor chain cannot be mixed with part of the new chain, otherwise it is easy to produce an impact during the transmission process and break the chain.

Finally, pay attention to the maintenance of the anchor chain during use. When the anchor is dropped, the anchor must not be stopped. When the anchor is lifted, the anchor chain must be washed to remove the debris and other debris; usually the anchor must be used. Keep the chain dry. Do not flush water into the chain locker when washing the deck; check it every six months. Arrange all the chain cables on the deck for rust removal, painting and inspection. The signs should be kept clearly visible; the chain is in use Lubricating oil must be added in time during work, and the lubricating oil must enter the matching gap between the roller and the inner sleeve in order to improve the working conditions and reduce wear.
