The modular design of the Wirtgen 2200 SM — the smallest surface miner with a working width of 2.20 meters and a cutting depth of up to 30 cm —- is of great practical advantage: the machine can be used as a classic surface miner for mining operations; with few modifications, it can also be used as high performance milling machine for road construction. This guarantees high machine efficiency.
For the ramp construction, the compact 2200 SM was used, with the optimal cutting depth of 25 cm in this terrain. Cut material was disposed in windrows.
The Wirtgen 2500 SM loads the crushed rock onto a waiting truck in a single pass.
