Wirtgen's new modular slipform paver easily switches between offset and crosspave configurations

Visitors to World of Concrete 2025 in Las Vegas will have the opportunity to see Wirtgen's SP 33 concrete slipform paver. Designed to be versatile, manoeuvrable, and efficient, the SP 33 can switch between two configurations: offset and crosspave.

Offset configuration

The new paver features a fully modular construction concept, enabling the paving of monolithic concrete profiles such as curbs and berms, rectangular profiles, concrete safety barriers up to a height of 1.3 metres (52 inches), and drainage and gutter profiles. In the offset paving configuration, it can effortlessly pave concrete slabs with a width of up to 2.2 metres (seven feet), also in combination with a trimmer up to 2.4 metres (eight feet) wide. 

Crosspave configuration and ECO mode

The crosspave configuration can pave slabs up to a width of three metres (10 feet) transversely to the direction of travel of the machine. Both solutions can be controlled by the new operating concept with an event-driven graphic display. The ECO mode detects every working situation without the need for manual intervention by the operator and ensures automatic, load-optimized regulation of engine output for optimum engine efficiency, maximum fuel economy, and low noise emissions.

The operator is further assisted by the AutoPilot 2.0 control system. The two crawler units with parallelogram swing legs at the front and a laterally adjustable crawler unit at the rear enable zero-clearance installation and maximum flexibility. This makes it appropriate for use on construction sites that demand a high degree of manoeuvrability and the paving of tight radii.

Completely coordinated machine technologies

The machines in Wirtgen's concrete paving train are engineered to help users to fulfill quality requirements for evenly paved concrete surfaces. The production system comprising a placer/spreader WPS 102i, an inset slipform paver SP 124i, and a texture curing machine TCM 180i will also be shown in Las Vegas.

Process-efficiency through AutoPilot 2.0 stringless paving 

Wirtgen's field-proven AutoPilot 2.0 control system, which is available for all offset pavers and placer/spreaders, elliminates the need for a physical stringline. This results in considerable savings in terms of time and effort and increases the safety of the paving crew. At the same time, the system precisely controls both the height adjustment and steering of the machine. A GNSS signal and, depending on the configuration, various local sensors — for example, an ultrasonic sensor on the machine — serve as a reference. It also enables fast and precise paving of tight radii and complex geometries.
