Factory Direct Supply HF158Y Open-Air DTH Drill Rig with CE/ISO Certification

The HF158Y high air pressure crawler open-air DTH Drill Rig is engineered for superior performance in demanding drilling applications. This robust machine combines hydraulic efficiency with pneumatic hammer technology to deliver optimal drilling results while minimizing energy consumption.

Featuring a powerful rotary power head, the HF158Y maintains consistent torque output during blasting hole drilling operations. The crawler chassis provides exceptional mobility with a 35° climbing ability, making it suitable for rugged terrain operations in mining, anchoring, and construction projects.

The innovative design separates the hydraulic system from the pneumatic hammer operation, significantly reducing air compressor requirements and operational costs. With mast compensation of 1200mm and once promotion of 3500mm, the rig offers excellent drilling stability and feed capacity.

Key advantages include high drilling efficiency, simplified maintenance procedures, and reliable performance in various geological conditions. The rig is particularly effective for applications in mining exploration, road building, water conservancy projects, and power station construction.

The HF158Y can be optionally configured for rock drifter or top hammer drilling applications with additional modifications, providing flexibility for specialized drilling requirements.
