Single bucket excavator is mainly composed of engine, hydraulic system, working device, traveling device and electric control. The hydraulic system consists of a hydraulic pump, a control valve, a hydraulic cylinder, a hydraulic motor, a pipeline, and a fuel tank. The electrical control system includes a monitoring panel, an engine control system, a pump control system, various sensors, and solenoid valves.
According to its structure and application, it can be divided into: crawler, tire, walking, full hydraulic, semi-hydraulic, full swing, non-full swing, general type, special type, articulated type, telescopic arm type and other types.
The working device is a device that directly completes the excavation task. It consists of three parts: a boom, a stick, and a bucket. Boom lift, boom extension and bucket rotation are all controlled by reciprocating double-acting hydraulic cylinders. In order to meet the needs of various construction operations, hydraulic excavators can be equipped with a variety of working devices, such as digging, lifting, loading, leveling, clamps, bulldozing, impact hammers and other operating tools. The slewing and walking device is the body of a hydraulic excavator. The upper part of the turntable is provided with a power device and a transmission system. The engine is the power source of the hydraulic excavator. Most of the diesel engines are used at convenient locations. Electric motors can also be used instead.
The hydraulic transmission system transmits the power of the engine to hydraulic motors, hydraulic cylinders and other actuators through hydraulic pumps, pushing the working devices to complete various tasks.
