The Doofor DF540L-BLTG-2M Rock Drill is a Hydraulic Drifter in the 14kW size power class with two OMS-type rotation motors and a BLT-flushing head.
The DF540L-BLTG-2m Rock Drill is designed for Bolting, general excavations, and Ground Stabilisation.
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.
The flushing media can be water or air or even grout (limitations apply).
BLT-versions are protected with multiple sealing points and a Hermetic Rotation Mechanism for demanding underground conditions.
Available shank adapters are R32, T35, R38, T38, and T45.
This Rock Drill can be equipped with stainless steel, separated flushing head for Underground Mining, Bolting, and Grouting.
Optimal maximum hole diameter for the DF540L-BLT-2M is 64 mm.
