Δ Introduction:
hydraulic rock drill is the result of our more than 10 years' effort, It is suit for soft to hard rock, and expansive soil, cobble stone, rock with earth, special stratum underwater, and also apply for building and road demolition construction.
It's the best choice to replace pneumatic rock drill. 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
Δ Feature:
Small motility
Fast drilling
Easily operate
Low noise
Simple structure
Reliable work
Easily repair
Easily move
Δ Application:
Tunnel dig in highroad and railway project.
Construction and Civil engineering
Quarry industry and Mining work.
Δ Compose:
BH28 series hydraulic rock drill can connect with 1-20 rock drills to suit for different working condition.
The drilling rig include:
Hydraulic power station
Hydraulic rock drill
Hydraulic leg and rack.
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.
