Core Drilling Rig
Our core drilling rigs are widely used in engineering and geological exploration for large diameter holes and shallow drilling in petroleum and natural gas mining, tunnel ventilation, drainage, water well projects and foundation pile construction. Featuring computer control, safe and efficient operation, and a comfortable user experience, the core drill rig models include HF-2, HF-4, HF-8, HF-42, and HF-44A. Each of our oil drilling equipment has passed ISO9001:2000 and CE Quality System Certification.
Hanfa Group’s oil rigs are exported to America, Africa, Asia and Australia. We provide quality products and services as well as detailed instruction in using and maintaining the core drill rigs and skilled technicians for on-site troubleshooting.
1. The compact structure and small chassis makes the core drilling rig mobile and easy to transport.
2. A hydraulic system gives the land rig convenient operation.
3. Uses diesel engine power so our oil drilling rig can be used in any terrain.
1. The HF-4 core drilling rig is used in mineral mining and has a diamond bit or tungsten-carbide tipped bit.
2. The oil and gas well drilling equipment is used in geological engineering, ground water exploration, shallow oil and natural gas exploration, and ventilation and drainage projects.
The HF-8 core drilling rig is used for medium and deep holes and has a diamond and carbide-tipped bit for a strong drilling performance. Featuring mechanical transmission, spindle rotation, and hydraulic feeding, the core drilling equipment is used for prospecting metallic and nonmetallic solid mineral deposits, shallow oil and natural gas exploration, geothermal well digging.
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).
The HF-44A core drilling rig is designed with a diamond drill bit and alloy drill bit. Used for engineering geological exploration, natural gas mining, mine tunnel ventilation, drainage, water well drilling and large diameter foundation pile construction, the land drilling rig is safe, efficient, and reliable with computer control.
