Stage electric hoist chain maintenance: key steps and techniques

　　1、 Cleaning - laying the foundation for maintenance

　　The Importance of Daily Cleaning

　　The stage electric hoist chain will accumulate dust, oil stains, and various impurities during use. If these dirt are not cleaned in time, it will increase the wear of the chain and affect its performance. Therefore, the chain should be cleaned promptly after each use.

　　Cleaning methods

　　You can use a clean soft cloth dipped in an appropriate amount of neutral cleaner to gently wipe the surface of the chain to remove dust and oil stains. For stubborn stains that are difficult to remove, a small brush can be used for brushing, but care should be taken to avoid damaging the surface of the chain. After cleaning, dry the chain with a clean dry cloth to ensure that the surface of the chain is dry and prevent rusting.

　　2、 Lubrication - Keep the chain running smoothly

　　The function of lubrication

　　Proper lubrication can reduce friction between the chain and sprocket, reduce wear, improve the transmission efficiency of the chain, and also extend the service life of the chain.

　　Lubrication timing

　　The chain should be lubricated regularly. Generally, it is more appropriate to lubricate it every 1-2 months depending on the frequency of use. If the stage electric hoist is used frequently or in harsh environments, the lubrication frequency can be appropriately increased.

　　Lubrication method

　　Choose specialized chain lubricant, evenly drip the lubricant onto each link of the chain, and rotate the chain to allow the lubricant to fully penetrate the interior of the chain. Be careful not to use too much lubricating oil to avoid contaminating the stage environment with dripping oil.

　　3、 Inspection - timely detection of problems

　　Appearance inspection

　　Regularly inspect the appearance of the chain to see if there are any deformations, cracks, broken chains, etc. If obvious deformation or cracks are found in the chain, the chain should be replaced in a timely manner to ensure the safe operation of the stage electric hoist.

　　Wear and tear inspection

　　Check the wear level of the chain, mainly by examining the wear condition of the chain links. Generally speaking, if the wear of the chain link exceeds 10% -15% of the original thickness, it is necessary to consider replacing the chain. At the same time, it is necessary to check the meshing of the chain and sprocket. If the meshing is poor, it may lead to increased chain wear.

　　Stretching inspection

　　Measure the length of the chain and compare it with the standard length of the new chain. If the stretching amount of the chain exceeds 3% -5% of the original length, it indicates that the chain has been excessively stretched and should be replaced in a timely manner.

　　4、 Storage - protect the state of the chain

　　Storage environment

　　When the stage electric hoist is not in use, the chain should be stored in a dry, well ventilated place to avoid damp and corrosive environments. You can apply a layer of rust proof oil on the surface of the chain to prevent it from rusting.

　　Chain organization

　　Before storage, the chain should be loosened to avoid being in a tight state. You can neatly wrap the chain around a dedicated storage rack to prevent it from getting tangled or knotted.

　　The maintenance of the stage electric hoist chain is crucial for the smooth progress of stage performances. Through a series of maintenance measures such as cleaning, lubrication, inspection, and storage, the performance of the chain can be ensured to be good, the service life of the chain can be extended, and it also provides strong guarantee for the safe operation of the stage electric hoist.
