Common excavator structures include, power plant, working device, rotary mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities.

The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive components through the hydraulic pump to promote the action of the working device, so as to complete a variety of operations.

Excavator walking device

Excavator walking device is chassis, including track frame and walking system, mainly composed of track frame, walking motor + reducer and its pipeline, driving wheel, guide wheel, sprocket, support wheel, track, tension buffer device, its function is to support the weight of excavator, and drive wheel transmission power into traction, to achieve the whole machine walking.

The frame assembly (namely the track walking frame assembly) is an integral welding part, using an X-shaped structure, its main advantage is that it has a high bearing capacity. The frame assembly is welded in three parts: the left longitudinal beam (the left track frame), the main frame (the middle frame) and the right longitudinal beam (the right track frame). The weight of the frame assembly is 2 tons.

The central rotary joint is the hydraulic component connecting the rotary platform and the chassis oil circuit, it ensures that the rotary platform rotates at any Angle, the walking motor can also distribute oil normally, the rotary joint is 5.
