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/cm 2). 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.

The smallest roadheader we have has a loading width of 3.5 m, which can be customized smaller if the customer requires. Our most common roadheader used for tunneling – the MT 720 – has a 4.56-m wide loading table. For tunneling projects, the two big models MT 720 and MT520 represent about 90 percent of what we build. ...
