The SP 33 Enables Concrete Paving in Offset and Crosspave Modes

 


Wirtgen recently showed the SP 33 slipform paver for the production of monolithic concrete profiles. It can be used for paving in both offset and Crosspave modes, enabling the realization of various paving applications with only one machine.

Thanks to its modular construction concept and a wide range of setting options, the machine can be configured for use in almost all situations encountered on construction sites. Two crawler units with parallelogram swing legs at the front and a laterally adjustable single crawler unit at the rear enable zero-clearance paving and maximum flexibility. In offset mode, it can pave curb and gutter profiles, rectangular profiles, and concrete barriers up to a height of 1.3 m as well as sewer and drainage channel profiles. Concrete slabs with a paving width of up to 2.2 m can also be realized without any problems, also up to a width of 2.4 m in combination with a Trimmer. In Crosspave mode, the track units are turned by 90° and the machine then paves transverse to the direction of travel. The slipform mold is centrally mounted under the machine enabling the paving of slabs with widths of up to 3.0 m. The quick and easy conversion from one paving mode to the other makes the machine extremely versatile. In addition to delivering precise paving results, the capabilities offered by the machine also make it a particularly cost-efficient paving solution.

The operator is assisted by the AutoPilot 2.0 control system, a stringless paving system for all offset pavers and placer/spreaders that eliminates the need for a physical stringline, which leads to considerable savings in terms of time and effort and increases the safety of personnel on the construction site.
