Performance Characteristics
- The main rotary and pull-back hydraulic pumps are cast-iron pumps rated for high pressure, delivering long service life.
- Two-speed rotation and three-speed thrust/pull-back with pilot proportional control provide infinitely variable speed adjustment.
- Rotation and thrust/pull-back are controlled by multifunction pilot joysticks that integrate all main operating movements into one ergonomic control point — simple, convenient, comfortable, and efficient.
- Crawler travel offers two speeds with electro-proportional wire control for safe, reliable operation (optional).
- 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.
- A clamp spring buffer device prevents accidental drill-rod thread or clamp damage caused by operator error.
- Gear and rack transmission with dual pull-back motor reducers drives the rotary head trolley forward and backward.
- The rotary head is driven by a piston motor, delivering high torque and strong impact resistance for complex formations.
