From the appearance, the excavator is composed of three parts: working device, upper turntable and walking mechanism. According to its structure and purpose, it can be divided into: crawler type, tire type, walking type, full hydraulic, semi hydraulic, full rotation, non full rotation, general type, special type, articulated type, telescopic boom type and many other types.

The working device is a device that directly completes the excavation task. It is hinged by three parts: boom, stick and bucket. Boom up and down, arm telescopic and bucket rotation are all controlled by reciprocating double-acting hydraulic cylinders. In order to meet the needs of various construction operations, the excavator can be equipped with a variety of work devices, such as digging, lifting, loading, leveling, clamps, dozing, impact hammers and other work tools.

The slewing and walking device is the body of the hydraulic excavator, and the upper part of the turntable is equipped with a power device and a transmission system. The engine is the power source of the excavator. Most of the diesel is used in a convenient place, and the electric motor can also be used instead.

The transmission mechanism transmits the power of the engine to hydraulic motors, hydraulic cylinders and other actuators through the hydraulic pump, and pushes the working device to move, thereby completing various tasks.
