Features

1. High-Torque Power Head
Delivers a maximum output torque of up to 280–300 kN·m with a speed range of 6–28 rpm (optional high-speed dumping up to 70 rpm), ensuring efficient penetration in hard rock, gravel, sand, and dense soil layers[3][5][6].

2. Robust Drilling Capacity
Boasts a maximum drilling diameter of 2500 mm (1800 mm with casing) and a depth of up to 86 m (6-section mast), supporting a wide range of pile applications for large-scale projects[3][4][8].

3. Stable & Durable Structure
Features a heavy-duty box-type mast and a dedicated hydraulic telescopic chassis with 360° adaptability, providing superior anti-tilting stability, balanced weight distribution, and long-term structural reliability.

4. Efficient Hydraulic System
Equipped with a load-sensitive hydraulic system for fast, responsive control and optimized power distribution, reducing energy loss and fuel consumption while enhancing overall operational efficiency.

5. High-Performance Winch System
Main and auxiliary winches offer up to 280 kN lifting capacity with a speed of 65 m/min, enabling fast and safe hoisting of drill rods and tools for uninterrupted workflow[5][6].

6. Intelligent & User-Friendly Controls
Features a 10-inch HD touch screen with real-time monitoring, automatic mast leveling, one-key soil dumping, and fault self-diagnosis, simplifying operation, improving precision, and reducing operator fatigue[8].
