The Quasan QS-220 fully hydraulic support drilling rig stands out in the construction industry with its advanced features and superior performance. This machine integrates a top-driven hydraulic power head, delivering a torque of 220 kN·m, which enhances drilling efficiency by 18% compared to traditional gearbox systems and significantly reduces the risk of jamming. Its intelligent control system, equipped with BeiDou positioning and adaptive oil pressure modules, ensures real-time monitoring of drilling verticality, keeping deviations within ±0.5°, thus minimizing rework rates. 

The modular design allows the rig to be disassembled into six components, facilitating swift assembly in challenging terrains like mountains and tunnels, while cutting transportation costs by 30%. Additionally, the rig features a load-sensing variable hydraulic system, which optimizes engine and pump efficiency, reducing heat generation and ensuring stable operation. The automatic pipe feeder further boosts productivity by automating the supply of drill pipes, reducing labor intensity and improving workflow efficiency. These innovations make the QS-220 a cost-effective and reliable solution for support drilling applications, offering remarkable value in terms of performance and adaptability.
