Tunnelling and mining

The ALPINE MINER AM 50 is a boom-type roadheader designed to cut medium-hard rock with an unconfined compressive strength of up to 90 MPa (800 kp/cm2).

The machine can, however, also take thin seams of harder materials in its stride should these be encountered in a working face.

This means that the AM 50 can cut most rock with economic efficiency. Thus, the AM 50 has a wide range of applications: roadheading in the mining and mineral industry, tunnel driving in civil engineering works, and face work in many mining situations.


The ALPINE MINER AM 50 moves on individually driven crawler tracks powered by electric motors. It is designed to negotiate gradients of up to ±18 gon. Structural advantages such as easy dismantling, low height, and low weight make it suitable for use in· all mining conditions.

The machine is designed for a maximum cutting range of 4.0 m vertically and 4.8 m across. The selective cutting principle, with which the cutter boom can be swung in all directions, makes it possible to cut any profile within the indicated range without moving the machine.

Attachments are also available to give the machine a greater upward reach. Because of the machine's easy mobility, the cross-cut range does not have to be extended.
