MHD1838HD+ Hydraulic Drifter

Equivalent to COP 1838HD+ Hydraulic Drifter 

High productivity and superior drill steel economy are produced by an effective hydraulic dual-damping system with a floating adaptor. High torque and great speed control are guaranteed by a strong stepless variable and reversible rotating motor. Pressurised, lubricated mating surfaces and side bolts, as well as separate lubrication of the front head and driver, boost productivity while reducing downtime.

FAQ’s

The MHD1838HD+ hydraulic drifter is designed as an equivalent to the COP 1838HD+ class hydraulic rock drill and can be used on compatible underground drill rigs with similar mounting arrangements, hydraulic connections, and feed beam systems.
Email: salessupport@mindrill.com

The MHD1838HD+ is suitable for demanding underground mining and tunneling operations including face drilling, production drilling, long-hole drilling, and drift or tunnel development. It performs efficiently in medium-to-hard rock conditions where high impact energy and torque are required.

The drifter uses a hydraulic dual-damping system with a floating adapter and a variable reversible rotation motor to provide stable drilling and efficient energy transfer. Pressurized contact surfaces and proper lubrication reduce component wear, prevent jamming, and extend service intervals, resulting in higher penetration rates and less unexpected maintenance downtime.

Yes. Many service and wear components of the MHD1838HD+ are compatible with COP 1838HD+ class parts, allowing easier maintenance, quicker replacement, and availability of commonly used consumables in the field.

Yes, MHD1838HD+ delivers high impact energy and efficient energy transfer, enabling fast penetration in abrasive and dense rock formations.
