Advantages
Core Performance & Parameters

- Powerful Engine: 221kW Dongfeng Cummins electronically injected diesel engine — strong power, low noise, low fuel consumption, and reliable operation.
- Exceptional Drilling Capacity: Max torque 34000N·m, rotation speed 0-140rpm; max thrusting/pulling force 750KN (boost up to 1500KN); 50m/min fast feed speed, significantly improving construction efficiency.
- Key Specifications: 850L/min max mud pump displacement (10Mpa pressure), Φ102mm×4500mm rod size, Φ1000mm reamer size; entry angle 8°~20°, adaptable to diverse terrains.
- Compact Design: 9900mm×2250mm×2670mm dimensions, 18.86t weight — easy to transport and deploy in narrow urban spaces.
Advanced Technical Features
- Top-Tier Hydraulic System: All hydraulic parts are international top-tier products; spindle rotation adopts closed system, push-pull/auxiliary systems use load-sensitive systems (volumetric speed control) — high transmission efficiency, low heat, energy-saving.
- Patented Intelligent Functions: Dual-motor three-speed design with patented dynamic gear switching (switch gears during work); patented constant torque control (preset torque for scientific hole expansion); patented top-up override protection (reduces drill pipe thread wear).
- Smart Control: CAN bus system + Danfoss original controller + 7-inch display — fast response, friendly interface; German Jessman multi-function handles (one-click unbuckling, cruise control), easy operation.
- Enhanced Adaptability: Swing drilling function (adapts to strata with failed direction change); proprietary rock mode (good micro-movement, high precision for rock drilling); built-in 2-ton crane (convenient drill pipe loading/unloading).
Safety & Durability

- Multiple Protection Systems: Rotation anti-impact overload protection, push-pull anti-rebound system, active oil replenishment system — reduces failure rate, protects hydraulic components.
- Efficient Mud Control: Mud displacement adjustable to any value as needed — saves mud, prevents drill bit clogging, ensures stable drilling.
- Long Service Life: Conservative design with high-quality components; external flushing integrated system — extends machine lifespan, lowers maintenance costs.
