95-3 HQ 500m 75KW Motor Power Hydraulic Underground Tunnel Drilling Rig
Underground Drilling Rig is suitable for drilling holes for the purpose of mine exploring; also they could be used in railway engineering, tunneling and water conservancy project. You will surely benefit a lot by its excellent and reliable performance.
Underground drilling rig is composed of power unit, machine body, control panel, rotation unit, rod holder and mud pump.
1. Oil pump drives the motor to rotate, hydraulic cylinder works without turret.
2. The machine system of rotation, feed, pumping and clamping relies on fluid drive; make your drilling work more smooth than any other competitors;
3. Fast drilling speed, can drill holes from any angle in work tunnel by column, best applicability;
4. With V-guide, the products provide the highest concentricity about principal axis;
5. Easy to maintenance, repair, disassembly, installation and movement.
