As one of the representatives of heavy machinery and equipment, Liugong loaders play an indispensable role in engineering construction. However, to ensure the long-term stable operation of the loader, routine maintenance work is essential. Regular gear oil changes are a key task. So, how often should the gear oil of the Liugong loader be changed? It mainly depends on the working environment and strength of the loader. In general, under normal working conditions, it is recommended to change the gear oil after every 2000 to 3000 hours of operation. However, if the loader works in a harsh environment with high temperature, high humidity or high load for a long time, it is necessary to shorten the oil change interval to ensure the normal lubrication and heat dissipation of the gears. When changing the gear oil, you should choose a special gear oil that meets the requirements of the Liugong loader and follow the correct replacement steps. At the same time, it is also important to check other parts of the gearbox, such as filters, seals, etc., to ensure that they are in good condition. Through reasonable replacement cycle and correct maintenance methods, the service life of Liugong loaders can be extended, work efficiency can be improved, and greater value can be created for the enterprise.
