The old Liugong loader is a heavy machinery that is widely used in construction, mining, logistics and other industries. During use, the location of the tank is critical for both operation and maintenance. First of all, we need to clarify the model and series of the old Liugong loader, because different models of loaders may be different in terms of fuel tank design. In general, fuel tanks are usually located behind or to the side of the loader's cab for easy refueling and maintenance. For the fuel tank behind the cab, it is usually located above the loader frame, next to the rear of the cab. This design allows the driver to clearly see the fuel level of the fuel tank when operating the loader, so that the fuel can be replenished in time. And for the side tank design, the tank is usually located on the side of the loader frame, parallel to the cab. This design makes refueling more convenient, simply by extending the refueling gun into the tank port. In addition to the location of the fuel tank, we also need to pay attention to the capacity of the fuel tank and the design of the fuel filler. The capacity of the fuel tank determines how long the loader can continue to work after a refueling, and the design of the fuel filler affects the convenience and safety of refueling. In conclusion, knowing the location of the fuel tanks of older LiuGong loaders is essential for daily operation and maintenance. Only by knowing the correct tank position can we better carry out refueling and maintenance operations to ensure the normal operation of the loader.
