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.
