Performance Characteristics
- Equipped with a Cummins Stage IV electronically controlled turbocharged diesel engine, delivering strong power output with energy-saving and environmentally friendly performance.
- Hydraulic and electrical systems are engineered for high reliability, low failure rate, and easy maintenance.
- Core system components use imported or joint-venture brands. The rotary head uses original French Poclain low-speed high-torque motors with direct drive, effectively solving the traditional problem of short gearbox service life caused by heat buildup.
- The rotation circuit uses a closed-loop system with closed-loop piston pumps paired with French Poclain low-speed high-torque motors to deliver both high torque and high-speed output. In closed-loop hydraulic circuits, Poclain motors provide strong impact resistance and long service life even in rocky and complex formations. Thrust/pull-back and auxiliary circuits use Yuken hydraulic pumps for high efficiency and reliability.
- Gear and rack transmission with two sets of dual-speed piston pull-back motor reducers drives the rotary head trolley; rotation offers two speed ranges and thrust/pull-back offers three speed ranges, all infinitely adjustable.
- Rotation and thrust/pull-back use pilot control with multifunction joysticks integrating auxiliary functions for comfortable, simple operation.
- A four-bar linkage boom lifting mechanism keeps the tracks firmly on the ground even at maximum drilling angles, effectively ensuring rig stability during both drilling and pull-back operations.
- The clamp is angled 10 degrees inward toward the operator, making clamp operations easy to observe and monitor.
- Crawler travel offers two speed ranges for faster site relocation; the integrated manual/wire-controlled travel system is safe and reliable, with improved operator visibility.
- Welded steel chassis with rubber track shoes provides strong traction and prevents damage to paved road surfaces.
- Equipped with a Cummins Stage IV electronically controlled turbocharged diesel engine, delivering strong power output with energy-saving and environmentally friendly performance.
