Easy ways to get the answers you need.

overview

HF038 is an All-In-One hydraulic DTH drilling rig, which brings you more automation, higher working efficiency, better reliability and simpler operation. The FOPS-ap proved cabin and automatic pipe handling system come standard.Heavy-duty undercarriage with wide tracks ensures both extreme maneuverability and improved safety.The hydraulic dust collecting system meets the latest environmental protection regulations and it's a reliable solution to realize the modern green mining.

Main features

*Automatic drilling, single operator

*Imported Rexroth and Eaton hydraulic control unit ensures strong torque output to meet large hole drilling needs

*Extendable heavy-duty boom has a large drilling coverage to increase working efficiency. 

*The diesel engine offers strong power. Impacting, feeding and rotating rate can be variably adjusted to suit different rock formations

*Imported Airman two-stage air compressor can switch between two compression stages, featuring a 24bar working pressure and 23.5m3/min FAD, increases penetration rate and hole quality.

Efficiency

When the engine starts up, the auxiliary electric compressor wil starts first to keep the main compressor load at a minimum leve so it helps the engine start more smoothly and reduce the start-up.wearThe boom structure has three degrees of freedom to ensure a wider range of drilling angles.

Rigidity

The heavy-duty undercarriage features robust structural strength, wide tracks (500mm) and excellent grade ability, which all ensure better stability while drilling.The feed system is driven by planetary gearbox and chain. The durable high-strength chain can be easily adjusted. The bearing roller type sliding plates have a long service life and are easy for maintenance.

Convenience

Service doors can be fully opened to provide large space and easy access to maintenanceThe rig's operating parameters, instructions and warnings all can be clearly displayed on the dashboard, easy for the operator to monitor.

Safety

The sealed air-conditioned cabin is made with FOPS which meets EU and US safety protection standards. Large windows provide the operator with great visibility to precisely control the rig. The ground clearance is over 400mm giving the rig extreme maneuverability on various tough terrain.
