1. Complete functions
The advancing beam at two stations is available and it is equipped with a magazine with a storage capacity of 10 bolting rods, along with an optional protective netting module. It is capable of performing the following tasks: drilling, netting and installation of rock bolting rods.
2. High safety
Operators are protected by the ceiling, far away from the danger area.
3. High efficiency
The stepped piston is used for the high-frequency rock drill and this can improve the transmission efficiency of impact wave, increasing drilling speed and reducing the consumption of drilling tools.
4. Good view for the operator
The articulated chassis of four-wheel drive ensures the flexible, quick and safe driving in narrow tunnels.
5. Considerable space
Considerable space and automatic functions enable the driver to concentrate on drilling in a safe, fast and accurate manner.
6. Easy maintenance
All the relevant parts are protected from the outside environment and are easy to maintain.
