The main pump is one of the important hydraulic parts of excavator that drives the vehicle with hydraulic power. It converts kinetic energy generated from the engine to hydraulic energy. With the supplied kinetic energy from the engine, the pump regulates flow rate with displacement of the piston.
The main control valve provides independent operation of all the excavator components. It receives hydraulic oil from the main pump and distributes the oil to the hydraulic actuators (travel motor, swing motor, cylinders, etc.).
The travel device consists of traction motor and speed reducer, and drives excavator by rotating tracks or wheels. Hydraulic energy is supplied from the traction motor, converted to mechanical energy and transmitted by speed reducer.
