CAT Large Excavator 349F

The working principle of the CAT 349F excavator is based on the hydraulic system, which mainly includes the following parts:

Engine: Provides power and drives the hydraulic pump.

Hydraulic pump: Converts the mechanical energy of the engine into hydraulic energy and delivers high-pressure oil.

Hydraulic cylinder: Pushes the piston through the pressure of the hydraulic oil to achieve various actions of the excavator.

Control valve: Adjusts the flow direction and pressure of the hydraulic oil and controls the actions of the hydraulic cylinder and hydraulic motor.

Hydraulic motor: Converts hydraulic energy into mechanical energy and drives the rotation and travel devices.

Working device: Includes boom, dipper and bucket to perform tasks such as excavation and loading.
