Everyone knows that the lifting machinery and equipment we use every day need to be cleaned. Only by cleaning up the stains on time will the life of the equipment be prolonged in order to reduce costs. The same is true for group hoists. The group hoist we use is generally installed in an open-air environment. It is exposed to wind and sun all year round. There is more and more dust in the working environment. There is a lot of dirt in the gaps of the equipment. The places that everyone cares about will cause corrosion to the products if they are not cleaned for a long time. After the group hoist has been used for a period of time, it is inevitable that dust will fall in, and the chain and internal parts will also experience different degrees of wear. At this time, timely cleaning and maintenance operations are required. Only in this way can the group crane electric hoist be effectively reduced. Wear and extend life. So how do we do the cleaning work? The first step of cleaning is also the most basic work. It is the prerequisite for maintenance. After long-term use, there will be dirt in the cover and the gaps of the components. Failure to clean up in time will cause the efficiency of the group hoist to decrease When cleaning, we can wipe with a rag, and the crevices can be wiped with a rag wrapped iron wire. Only when it is cleaned, the lubrication is meaningful, otherwise it is useless. The chain of the group hoist should be lubricated with oil. In addition, pay attention to whether the oil in the gear box is enough. Some gear bearing parts also need to be filled with appropriate amount of lubricating oil. The correct cleaning and maintenance of the group hoist can effectively reduce the friction of the components, and can prevent rust, extend the life of the group hoist, and the efficiency will be significantly improved. The group hoist does not specify how often to clean up, as long as everyone develops a habit of cleaning regularly.
