PRODUCT DESCRIPTION
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.
