The Wirtgen Group is participating at the World of Concrete 2020 to present its inset concrete paving train, consisting of two machines being unveiled at the show – the WPS 62i placer/spreader and the SP 124i slipform paver – as well as the TCM 180i texture curing machine. The small SP 25i and SP 15i concrete pavers rounding out the range of inset and offset solutions are also displayed, while the Autopilot 2.0 3D control system is demonstrated live in the outdoor area.
Wirtgen’s new WPS 62i placer/spreader - with two track units - has made its global premiere at the show. For preplaced reinforcing steel, the concrete must be supplied from the side. The WPS 62i/WPS 62 is suitable for such an application. As the first machine in the Wirtgen paving train, the placer/spreader passes over the reinforcement in front of the slipform paver while the concrete is fed from the side and distributed evenly over the entire working width (between 3.65 and 7.3 m in the case of the WPS 62i/WPS 62, and a paving thickness of up to 500 mm).
Due to the fully modular machine design with standard hydraulic quick-change couplings, the WPS 62i/WPS 62 can be easily reconfigured and prepared for the respective jobsite situation or for transport, which also increases the machine’s uptime.
In addition, the Wirtgen SP 124i/SP 124 slipform paver has a working width of up to 12 m, equipped with four steerable and slewing crawler units. It is also available with an optional new hydraulic rotational drive system with a steering angle of up to 260 degrees. The additional manoeuvrability of the machine allows the operator to quickly and flexibly adapt to the conditions on the jobsite. The machine’s narrow profile and reduced track line also allow the operator to pave close to obstacles.
The four crawler units of the SP 124i/SP 124 can be switched to rotation mode at the push of a button. Because of this, the machine can turn almost on the spot and directly produce the next lane in the opposite direction without wasting any time on repositioning. For transport, the swing legs are hydraulically swung in, further optimising the transition from paving and decreasing downtime.
As the third machine in the Wirtgen paving train, self-propelled texture curing machines such as the TCM 180i/TCM 180 guarantee the success of professional curing of concrete pavements. It is fitted with an automatic spraying and brooming system and directly follows behind the slipform paver to create the desired surface texture. Finally, the spraying system applies a dispersion to the fresh concrete surface, thus preventing it from drying out prematurely. The modular design of the TCM 180i/TCM 180 supports working widths of 4 to 18 m.
In addition, with its newly developed AutoPilot 2.0, Wirtgen continues to be synonymous with quality and precision in concrete paving. The 3D control system can now create as many offset and inset profiles as required even more cost-effectively and precisely. In doing so, the system either uses an existing data model or creates a new digital data model on site, thereby eliminating the need for a surveyor to create a geodetic data model in advance. It also eliminates the time-consuming measuring, mounting and removal of stringlines, making the entire operation faster and more cost-effective. Wirtgen offers the AutoPilot 2.0 for the SP 15/SP 15i and SP 25/SP 25i models. The company said it is also possible to upgrade machines with the new system.
