Performance Characteristics
- Equipped with a Cummins Stage IV electronically controlled turbocharged diesel engine, delivering strong power output and stable performance.
- The rotation circuit uses a closed-loop system with Sauer-Danfoss main pumps paired with Poclain low-speed high-torque motors, ensuring both high torque and high-speed output. In closed-loop hydraulic circuits, Poclain motors provide strong impact resistance and long service life even under rocky and complex formation conditions.
- The pull-back main pump is a load-sensing proportional piston pump, offering high efficiency, high pressure rating, and long service life.
- Gear and rack transmission with proportional variable pull-back motors and gearboxes drives the rotary head trolley.
- The clamp is angled 10 degrees inward toward the operator, making clamp operations easy to observe and monitor.
- Welded steel chassis fitted with rubber track shoes for high structural strength and long service life; crawler travel control integrates both manual and electric control for safe, reliable operation.
- Standard equipment includes a rotating rod handler, enclosed cabin with air conditioning, and onboard crane — reducing auxiliary crew workload and improving construction efficiency.
- Rotation and pull-back use friction-position pilot joysticks with proportional control and infinitely variable speed adjustment for operator comfort and reduced fatigue.
- Standard equipment includes a rotating rod handler, enclosed cabin with air conditioning, and onboard crane — reducing auxiliary crew workload and improving construction efficiency.
