Product introduction:
The light roof bolter is portable, which integrates drilling, mixing, and installation of bolts and cables. It is suitable for various rock roadways, coal roadways, and semi-coal rock roadways with roof hardness f≤10.
Technical features:
Super Light Weight
The machine adopts innovative idea to realize integration and make it an exquisite and compact outline, it is about 40% lighter than regular roof bolter, and thus the machine reduces work intensity and improves work efficiency significantly.
Large Power
With advanced pneumatic motor design concept, this machine consumes less air, however, delivers large power. The maximum power is 3.5kW, the largest in China till now, improving drilling efficiency by 20%.
No Aluminum Parts
Designed under European standards, it is free of aluminum parts, which is very safe to use in underground mines.
Lower Noise
An expand-chamber type silencer with built-in tubes is applied in this machine to restrain the noise below 89 decibel, the lowest among similar machines, which makes safe and healthy environment for the machine users.
Attractive Appearance
Unlike other similar machines with casting mould casing, our machine is good looking and high-end with the stainless steel unibody casing.
