Product Description

 CM358A Crawler Mounted Hydraulic DTH Drilling Rig

Crawler Mounted Hydraulic DTH Drilling Rig

Crawler Mounted DTH Drill Rig, Hydraulic Crawler Drills

In contrast to the pneumatic drilling rig, energy consumption (diesel or electricity) saves about 40% to 50%.

Borehole Diameter

90-165mm

Site Condition

CM358A crawler mounted hydraulic DTH drilling rig is mainly applicable to the blast hole drilling process of open pit mining, quarrying, hydropower project and road constructions.

Product Features

CM358A crawler mounted hydraulic DTH drilling rig adopts diesel engine (or electric motor)  and hydraulic oil pump assembly to provide power, allowing rigs to finish moving, rotating, feeding and lifting, as well as angle positioning. 

During operation only the percussive DTH rigs consumes compressed air and in contrast to the conventional pneumatic rigs, CM358A saves about 40%~50% of total energy.
