It's working efficiency is 5-10 times that of pneumatic one, while consuming 1/3 power of latter Drilling performance: Applicable to hard, semi-hard and soft rocks; According to different engineering requirements, we can offer various supporting devices for different working
Conditions: Manual hand-held, air ground jack, horizontal bracket for marble mining, and railway type for mines.
Δ Cost Compare:
Compare with pneumatic rock drill, the energy consume is only 1/3 of the pneumatic type, work efficiency is 2 times than pneumatic type, compositive economic benefits 3 times than the pneumatic type. That's because the hydraulic drill's impact frequency and impact power is higher than pneumatic one.
Compare with pneumatic one, hydraulic rock drill is lower noise, less vibration, trivial labor intensity, lower energy consumption, more huge impact energy, and more than 2 times faster drilling speed. It is an ideal tool to replace the pneumatic drill.
