220 SM 3.8

Maximum performance in soft rock

The design of the 3.8 m cutting drum unit of the 220 SM 3.8 / 220 SMi 3.8 models is optimised for the mining and quarrying of soft rock and guarantees maximum productivity and minimised operating costs.
The Surface Miner extracts natural resources with a uniaxial compressive strength of up to 35 MPa to cutting depths of up to 350 mm.
The 220 SM 3.8 / 220 SMi 3.8 models are the ideal choice for use in all mining and quarrying operations, regardless of their size.
Natural resources are extracted in high quality without drilling and blasting in a single, environmentally compatible operation.
When using the windrowing method, the extracted material is continuously deposited in rows behind the machine.

Unique, multi-functional offset and inset slipform paver

The multifunctional slipform paver builds a variety of monolithic profiles up to 2.0 high.
Concrete surfaces up to a paving width of 3.5 m can be applied both as an inset and offset method (not in combination with all options).
Single or two hydraulic parallelogram swing arms at the front and a hydraulically telescopic track unit at the rear enable extremely flexible paving.
The intelligent, electronic steering and control concept enables driving in extremely tight diameters and high adaptability to any construction site situation.
The machine can precisely control the reading from the offset wire via the offset radio WIRTGEN AutoPilot 2.0 or 3D applications.
