The three main sections of an excavator are the undercarriage, the house and the arm.

The boom, the front part that is attached to the cab itself and holds the arm, is also used.

The undercarriage includes tracks, track frame, and final drives, which have a hydraulic

motor and gearing providing the drive to the individual tracks. Undercarriage can also

have blade similar to that of a bulldozer. The house includes the operator cab,

counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the

undercarriage by way of a center pin. High-pressure oil is supplied to the tracks' hydraulic

motors through a hydraulic swivel at the axis of the pin, allowing the machine to slew

360° unhindered and thus provides the left-and-right movement. The arm provides the

up-and-down and closer-and-further (or digging movement) movements. Arms typically

consist of a boom, stick and bucket with three joints between them and the house.

Wide Bucket Capacity Options: The product offers a range of bucket capacities, including 0.65m, 0.8m,

8m, 0.35m, and 0.11m, providing customizable solutions for different projects.

The cab of this used excavator also has been cleaned and renewed which surely give better 

comfort to the operator. When you operate it by yourself you will love it for sure.
