Double Arm Hydraulic Drill 1. Applicant environment Especially
design for Underground coal mining, mainly do drilling operations
for Routine hole, Side Pradesh hole, Cut holes and other Boomer
Blasting holes. 2. Advantage: (Compared to pneumatic drilling rig)
*Energy saving: 55kw Two hydraulic rock drills are equivalent to
150kw Six pneumatic rock drills. *Longer life accessories:
Hydraulic pressure is 10 times more than Pneumatic pressure, which
resulted in little harm to piston, Maintenance cost is lower 30%.
And our drilling has automatic anti- jamming function.
*Environmental protection and low noise: Hydraulic rock does not
exhaust emission and oil, high visibility. Use hydraulic to crash
rock, no sound emissions, Noise could be lower down 10 decibels
than pneumatic drill. *High quality construction: After booming,
Underground size and appearance is still complete. Drilling
accuracy (eg: Drill depth and drill width)is very high. * Safe
operation: Driver's operating position is far away from operation
place. ItemUnitCMJ2-18 basic typeCMJ2-18 increased typeAppearance
