Performance Characteristics
- All major hydraulic components — including hydraulic pumps, motors, and control valves — are original imported brands.
- The diesel engine uses a reputable Sino-foreign joint-venture brand, delivering strong power and reliable performance.
- The main machine uses a crawler chassis drive with self-contained power for convenient site relocation, fitted with a 5-ton hydraulic crane.
- Rotation uses a piston motor with gearbox drive, delivering high speed and high torque, equipped with a spindle floating breakout device.
- The feed mechanism uses gear and rack drive, with both thrust and pull-back force rated at 6,000 kN.
- Both rotation and feed systems use closed-loop circuits with multi-range infinitely variable speed control for accurate, reliable, and efficient operation.
- The clamp uses a closed-structure three-jaw design with high clamping force, capable of traveling along the full length of the mast frame.
- The auxiliary system uses advanced negative-feedback electro-hydraulic proportional control for high efficiency and energy savings.
- The skid-mounted power station operates in parallel, with connections on both sides and 15-meter hoses connected to the main unit via self-sealing quick-release couplings.
- The rig is equipped with a separate, standalone control cabin.
