The Quasan QS-320, a fully hydraulic drill rig, excels in tunnel advanced support systems, particularly for preambles. Its core advantages stem from innovative design and robust performance in challenging geological conditions.

1. ‌Enhanced Power and Efficiency‌: Equipped with a high-torque hydraulic motor (22,000 N·m) and integrated rotary-percussion mechanism, it ensures efficient drilling through hard rock and unstable strata, minimizing downtime.

2. ‌Superior Stability and Control‌: The intelligent load-sensing hydraulic system and multi-joint linkage mechanism provide precise angle adjustments, critical for maintaining alignment in curved or inclined tunnels.

3. ‌Adaptability to Complex Conditions‌: Designed for extreme environments, it features anti-jamming technology and automatic rod handling, reducing risks of borehole collapse in loose or fractured formations.

4. ‌Safety and Durability‌: The auto-feeder and robust casing system enhance operational safety, while durable components ensure longevity in demanding projects like subway construction and slope stabilization.

These features make the QS-320 a preferred choice for ensuring tunnel integrity and accelerating project timelines.
