Full Hydraulic Diamond Core Rig Geotechnical Drilling Equipment
Hydraulic underground core drilling rig is suitable fro drilling holes for the purpose of mine exploring, also they could be used in surface coring, railway engineering, tunneling,construction and water conservancy project. You will sure benefited a lot by it excellent and reliable performance.
I. Main Features of the rig:
1. Oil pump drives the motor to rotate, hydraulic cylinder working without a turret.
2. The core drilling machine system of rotation, feed, pumping and clamping relies on the fluid drive; making your drilling work smooth than any competitor;
3. Fast drilling speed can drill holes from any angle in work tunnel by column, beat applicability;
4. With V-guide, the rig provides the highest concentrivity about a principal axis;
5. Easy to maintenance, repair, disassembly, installation and movement.
All hydraulic underground core drilling rig is composed of power unit,machine body,control panel,rotation unit,rod holder and mud pump.
II. Main Performance Parameters of HYDX-6
The figures in these tables have been calculated, based on field
experiences, and may be reasonably expected. Actual drilling
capacity will depend on in-hold tools and conditions, drilling
techniques and equipment used.
