Doofor DF540L-BLTG-2M is a hydraulic drifter in the 14kW size class with two OMS-type rotation motors and a BLT-flushing head. The rock drill is designed for bolting, general excavations, and ground stabilization. The DF540L-BLTG-2M has very low overhead and two rotation motors. Two rotation motors offer a stable, high torque while offering a high rotation speed necessary for patented high-frequency percussion.
