The WIRTGEN GROUP is an internationally operating group of companies in the construction machinery sector incorporating the traditional product brands: WIRTGEN, VÖGELE, HAMM, KLEEMANN and BENNINGHOVEN. As technological leader, we offer our customers mobile machine solutions for road construction and road rehabilitation, plants for mining and processing minerals or recycling material and for the production of asphalt.

WIRTGEN surface miners are primarily used for the selective mining of mineral deposits and pay minerals, from soft coal to hard limestone, in opencast operation. They cut, crush and load the material in a single working pass without the need for drilling and blasting, thus enabling the exploitation rates of mineral deposits to be increased significantly. Additional fields of application include routing operations in road construction or the lowering of tunnel floors.

With the 2200 SM, 2500 SM and new 4200 SM, WIRTGEN offers its customers three tried and tested performance classes which can be equipped with a large variety of options and customized to specific project requirements. All models can be designed for loading the material into dump trucks or depositing it as a windrow behind the machine. Over two dozen drum designs with, for instance, different tool spacings are available for the machines as standard cutting drums while additional special designs are developed and built to meet specific application requirements.
