MRT Emulsion Roof Bolter (Hydraulic Anchor Drill Machine)

High-Torque Emulsion-Driven Roof Bolting Machine for Underground Mining

Product Overview

The MRT Emulsion Roof Bolter is a high-performance anchoring machine powered by an underground emulsion hydraulic system. Compared with pneumatic roof bolters, it provides higher torque, stronger thrust force, and more stable drilling performance.

It is specially designed for medium and large-scale underground coal mines, suitable for hard rock formations and continuous bolting operations. Hydraulic roof bolters typically deliver significantly higher torque output than pneumatic types, making them ideal for demanding mining conditions.
