CM358 most efficient drilling rig for rock

most efficient drilling rig for rockCM358 crawler hydraulic down-hole drill 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%.CM358A(D)crawler hydraulic down-hole drill is mainly used in stonework drilling, such as water and electricity project, exploitation of open mine and road construction. Technical Parameters of CM358A(D) Drilling diameter: 105 - 165 mm Drilling depth: 40m Working air pressure: 1.2 to 2.4 MPa Air consumption: 11-21 m3/min Applied rock rigidity: f = 6 - 20 Propulsion stroke: 3400mm Outer size (length × width × height) (mm): 7000×2200×2100 Total weight: 6100kg Engine Power: 50KW (Yuchai) Pipe-rod changing length: 3m Maximum horizontal hole height: 3.37m Gradeability: 24°
