Mô tả chi tiết

Sự miêu tả

Outstanding power and rock penetrating ability

280kN · m high torque+300kN main winch+210kN pressure, high drilling efficiency in hard rock.
Rock adaptive technology: automatic matching of torque, speed, and pressure, making hard rock construction more stable and faster.

Stable and reliable, with a durable structure

The Sany special chassis (SY460R) has a low center of gravity, wide width, and strong construction stability.
New power head buffer device: shock absorption capacity increased by 4.3 times, motor/reducer life extended by 3 times.
Reinforced mast: high rigidity, anti fatigue, certified through fatigue testing.

Efficient, intelligent, and easy to operate

The main winch operates at 65m/min, with fast lifting and high hole forming efficiency.
Intelligent electronic control+self diagnostic alarm: real-time monitoring of faults, easy maintenance.
Single layer rope drum: Steel wire rope has a long service life and low failure rate.
