Hydraulic excavator is mainly composed of the engine, hydraulic system, working device, walking device and electric control parts. Hydraulic system consists of hydraulic pump, control valve, hydraulic cylinder, hydraulic motor, piping, tanks, etc. Electrical control system including control board, engine control system, pump control system, all kinds of sensors, solenoid valve, etc.
Hydraulic excavator generally consists of working device, rotary device and walking device of three parts. According to its structure and USES can be divided into: caterpillar, tyred, walking, hydraulic, hydraulic, rotary, and the rotary, general, special, articulated, telescopic jib type and other types.
The working device is done directly device for mining tasks. It consists of three parts such as movable arm, arm and bucket hinge. Movable arm ups and downs, the length of arm and bucket rotating reciprocating control double-acting hydraulic cylinder. In order to meet the needs of the various construction, hydraulic excavators can be equipped with a variety of work device, such as mining, lifting, loading, level off, clamp, bulldozing, impact hammer and other operation equipments.
The body of rotary and walking device is a hydraulic excavator, upper turntable is equipped with power plant and driving system. Engine is the power source of the hydraulic excavator, mostly using diesel at a convenient site, also can use motor.
Hydraulic drive system by the hydraulic pump of the engine power is passed to the hydraulic motor, hydraulic cylinder actuators, promote the working device, so as to complete all assignments.
