Details
RDH351 hydraulic down-hole drilling rig are developed on the basis of Atlas CM351 full-pneumatic model by RUIDA Machinery Company. It is wildly used in rock dig of open pit, railway road, hydroelectric industry, mining and other projects. It can also drilling hole by following pipe under different air pressure.
DongFeng Cummins engine with hydraulic pump forms the driving device. The hydraulic power drives the crawler travel, rod rotation and push, boom lifting erection, and machine leveling. It keeps the high efficiency and reliability features of CM351. At same time, the pressure air is only consumed by the drilling hammer, compared with CM351, the displacement of air compressor matched can be reduce 30%-50% , energy consumption reduce 40%-50%.
