Hydraulic hoist has been widely used in hydraulic engineering. It has high efficiency, reliable performance and safe operation. However, if the daily operation and maintenance is improper or not timely, the failure rate will be greatly improved, the reliability and safety will naturally be reduced, and even the operation accidents of sluice projects will be caused. Therefore, it is necessary and important to maintain the hydraulic hoist scientifically.
After debugging the hydraulic system, the oil in the tank should be replaced. After six months of initial use, the oil should be replaced once, and then every other year. When changing the oil, the oil tank should be cleaned to ensure the normal operation of the hydraulic system. All filter elements should be cleaned regularly. If the filter plug is serious or damaged, they should be cleaned or replaced in time.
