Как работает экскаватор?

Excavator works by using a hydraulic system to control the movement of the arms, bucket and cab. The hydraulic fluid is powered by a pump driven by the engine, which pressurizes the fluid and sends it to actuators that control the movement of the various parts of the machine. The operator uses joysticks or levers in the cab to control the direction and force of the fluid, which moves the arms and changes the position of the bucket. This allows the excavator to dig, lift, and move materials.
