Versatile, maneuverable and efficient describe the new WIRTGEN SP 33 slipform paver that has two configurations, which thanks to its fully modular construction concept, enable the paving of monolithic concrete profiles. These include curbs and berms, rectangular profiles, concrete safety barriers up to a height of 52 inches, and drainage and gutter profiles.

In the offset paving configuration, the SP 33 can effortlessly pave concrete slabs with a pave width of up to 7 feet, and in combination with a trimmer, up to 8 feet wide. The Crosspave version can pave slabs up to 10 feet wide transversely to the direction of travel of the machine. Both solutions can be controlled by the innovative 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 the ideal choice for use on construction sites that demand a high degree of maneuverability and the paving of tight radii.

Production System: WPS 102i, SP 124i and TCM 180i

With its concrete paving train orchestration, WIRTGEN also offers completely coordinated machine technologies and practice-oriented equipment variants. They help users to fulfill quality requirements, in particular regarding outstanding evenness of the paved concrete surface. The Production System comprising a WPS 102i placer/spreader, an SP 124i inset slipform paver and a TCM 180i texture curing machine was also on display at World of Concrete.

Stringless paving with AutoPilot 2.0 provides process efficiency

Conventional concrete paving methods rely on a physical stringline for controlling the paving process. As an alternative, WIRTGEN offers its field-proven AutoPilot 2.0 control system, which is available for all offset pavers and placer/spreaders. The need for a physical stringline is eliminated, which 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 serve as a reference. It also enables fast and precise paving of tight radii and complex geometrics.

Additional features of the SP 33 include a new slider bed belt conveyor for low wear operation, a better overview and easy cleaning, as well as an intuitive human-machine interface with an 8-inch color touchscreen display and ergonomic controls.
