Roadheader - Type SM 130
Roadheader - Type SM 130
APPLICATION
Tunnelling and mining
The standard design Miner SM 130 is a roadheader which was developed for the cutting extraction of medium hard rocks. The compressive strength is up to approx. 80 MPa single axis cube. Thin layered rocks of a higher strength within less hard rocks can also be cut.
This means that the roadheader is capable of excavating a considerable portion of sedimentary rock economically. Therefore, the applications for the roadheader SM 130 are very versatile. They range from heading operations in the mining and mineral industry to excavation of tunnels in civil engineering projects or as an extraction device.
ADVANTAGES
The Miner SM 130 moves on a crawler track, which are individually driven by hydraulic motors. It is able to work on upward and downward gradients of up to 20 gon. The easily dismountable modular construction, the low height and the low weight facilitate the application in narrow mine conditions.
The roadheader principle with the rotating cutter boom allows to drive any trapezoidal or arched profile from a central position within the limits of the greatest cross section.
