| The Wirtgen 2200 SM, introduced to the world at Bauma in Munich, in 2001, is the "all-rounder" for soft and medium hard rock. The 2200 SM is powerful, yet smooth running. With an operating weight of almost 56 short tons, the Surface Miner 2200 SM can achieve a cutting depth of nearly 13 inches over a total width of 7.2 feet in soft to medium hard rock. The machine is driven by a Caterpillar diesel engine with an output of 900 hp. Four large crawler tracks and smooth hydraulic four-track steering guarantee good maneuverability. Steering and advance speed controls are governed via joysticks. The advance speed control allows easy and infinitely variable speed regulation from zero up to the maximum travel speed of over 3 mph. The cut material is loaded to the front via a large conveyor system consisting of primary and discharge conveyor. The 3.6-foot-wide discharge conveyor can be adjusted in height and slewed to either side.
