<strong><li>Slipform pavers</li></strong> 
Offset pavers are used to produce monolithic concrete profiles such as protective concrete walls, kerb profiles, gutters or narrow paths.
<strong><li>Surface Miners and Cross Application Miners</li></strong> 
Ruggedly-built Surface Miners are used for the extraction of a wide range of primary resources by cutting in open cast mines.

Wirtgen

Constructed especially for the tough operating conditions encountered in open cast mining, Surface Miners extract primary resources such as coal, gypsum, rock salt, phosphate, bauxite or limestone with unconfined compressive strengths of up to 80 MPa with high purity and maximised exploitation of deposits. Centrally-located underneath the machine, the cutting drum can be customised to meet each customer’s specific needs.

Cross Application Miners are characterised by their suitability for a wide range of applications. For example, they are used on demanding infrastructure projects, for cutting road and rail routes, lowering tunnel floors and in the construction of harbours or water retention basins. Cutting drums are available for the mining of hard or soft rock. In most cases, the extracted material is loaded into road-legal construction site trucks with the machine’s integrated discharge conveyor.
