[0002] An excavator, also known as a digger or excavator loader, is a heavy-duty construction machine used for digging, moving, and transporting soil and other materials. It typically consists of a chassis, a rotating platform, a boom system, a hydraulic system, and a working device. Existing excavators mainly convert the chemical energy of diesel fuel into mechanical energy through a diesel engine, and then the mechanical energy is converted into hydraulic energy by a hydraulic piston pump. The hydraulic energy is then distributed to various actuators (such as hydraulic cylinders, swing motors, and travel motors) through the hydraulic system. These actuators then convert the hydraulic energy back into mechanical energy, enabling the movement of the working device, the rotation of the rotating platform, and the travel of the entire machine.
