Core Drilling Rig, HF-42
Main Features
1. The HF-42 core drilling rig has eight rotary speeds and a maximum torque of 3.5 KN•m (2580 lbf•ft).
2. With a large spindle I.D. of 93mm (3.66 inch), the core drilling machine is driven by hydraulic double cylinders with a long stroke of 600mm (23.62 inch).
3. Featuring high power capacity and a low oil temperature, the onshore oil rig uses a simplex hydraulic gear pump to supply oil.
4. A double-action hydraulic chuck provides a powerful clamping force.
5. This oil drilling equipment is lightweight, easy to disassemble into nine parts, and convenient to maintain and repair thanks to its compact structure and layout.
6. The core drill rig remains steady even at high drilling speeds because of its smooth movement and low center of gravity.
