Walking Principle: This crawler excavator adopts heavy-duty reinforced undercarriage and  tracks. High-strength track plates ensure reliable travel on complex job sites. The optimized ground contact design rationally controls ground pressure, improves the machine’s trafficability on clay, gravel, slopes and other working conditions, effectively reducing slipping and sinking risks, and adapting to various earthwork construction sites.

          Excavation Operation: It is equipped with backhoe working equipment. Excavation operations are completed by coordinated movement of three groups of hydraulic cylinders for boom, arm and bucket. The operator sends commands via pilot control handles. The load-sensing hydraulic system accurately transmits power to hydraulic cylinders of each working device, realizing boom lifting/lowering, arm extension/retraction and bucket excavation together with combined swing motions for smooth and efficient operation.
