358A crawler hydraulic down-hole drill rig adopts diesel motor (electric motor). Hydraulic oil pump unit offers power to hydraulic motor moving, turn-around, propulsion and lifting, and angle orientation of oil cylinder, etc, when drill is working, only the down-hole hammer consumes the compressed air, compared with whole-pneumatic drills, the consumption of energy(fuel or electricity) is saved by 40% to 50%.
358A(D)crawler hydraulic down-hole drill rig is mainly used in stonework drilling, such as water and electricity project, exploitation of open mine and road construction.
