Do electric hoist chains need to be coated with lubricating oil

　　Yes, in order to ensure the normal operation of the electric hoist, the electric hoist chain needs to be regularly coated with lubricating oil

　　1、 Lubrication of electric hoist chain

　　Electric hoist is a commonly used lifting machinery, and its chain is one of the main components for lifting and transmission. In order to ensure the normal operation of the electric hoist chain, regular lubrication is required. In general, the electric hoist chain needs to be coated with corresponding lubricating oil.

　　2、 Lubrication method

　　There are two lubrication methods for electric hoist chains: manual application and spray lubrication. The manual application method is suitable for small electric hoists. When applying, the surface of the chain needs to be wiped clean before applying lubricating oil. Spray lubrication is suitable for large electric hoists, and spraying lubricating oil can evenly cover the entire chain surface, saving time and effort.

　　3、 Maintenance methods

　　In addition to regularly applying lubricating oil, the electric hoist chain also needs daily maintenance. Firstly, it is necessary to keep the surface of the electric hoist chain clean and prevent dust and debris from entering the inside of the chain. Secondly, pay attention to the tension of the chain and maintain an appropriate tension. In addition, it is necessary to check the wear of the chain and sprocket, and replace severely worn components in a timely manner.

　　In summary, in order to ensure the normal operation of the electric hoist, the electric hoist chain needs to be regularly coated with lubricating oil. The lubrication method can be selected as manual application or spray lubrication. In addition, daily maintenance is necessary to ensure that the surface of the chain is clean, properly tensioned, and to replace severely worn components in a timely manner.

　　Routine maintenance and upkeep of electric chain hoist

　　1. It is common to apply lubricating oil to the chain: Generally, explosion-proof electric chain hoists should be properly lubricated after using for about 400-500 hours. You can use a cloth or brush to directly apply lubricant to the chain, or pour an appropriate amount of lubricant into the chain bag, and then run the chain without load so that both the chain and sprocket can come into contact with the lubricant. The time standard for refueling is to maintain the grease on the surface of the chain. Remember not to add butter.

　　2. Pay attention to checking whether the chain is worn. We can use the chain gauge provided at the factory for measurement. If the chain is worn, we should promptly determine whether to replace it;

　　3. Check the chain conductor and guide frame, especially the groove inside the guide frame, for any foreign objects, impurities, etc;

　　4. Check the wear level of the hook and the effectiveness of the tongue;

　　5. Is there any wear on the chain bag;

　　6. Regarding the motor brake, we recommend maintenance under normal circumstances and do not adjust the brake, except in special circumstances;
