Piloted‑Hydraulic Control Underground Core Drill Rig
Product Features:
The PHD (Piloted‑Hydraulic Control) Underground Core Drill Rig is renowned for its advanced and reliable technology. Suitable for both surface and underground tunnel conditions, it handles core exploration and various drilling operations including ventilation, dewatering and grouting holes.
The synchronized movement between the power‑head chuck and gripper enables easy operation and effectively eliminates the risk of rod drop caused by human error.
User‑friendly to operate: one single joystick completes make‑up, break‑out, fast feed and fast retract. Automatic floating function during make‑up and break‑out protects drill threads from damage.
Three working modes are available: drilling, rod feeding and rod retracting. Thanks to the coordinated chuck‑gripper action, working efficiency is greatly boosted with effortless operation.
Bidirectional pressure from the active power‑head cylinder adapts to all terrain conditions and ensures stable and safe drilling performance. Cumbersome manual pressure‑adjustment procedures are no longer required.
