Wirtgen Group will introduce an inset concrete paving train consisting of two new machines—the WPS 62i placer/spreader and SP 124i slipform paver, plus the TCM 180i texture curing machine—during World of Concrete (WOC) 2020.
In addition to the simulated paving train, the compact SP 25i and SP 15i concrete pavers will round out the range of inset and offset solutions Wirtgen will display at its booth #C5426.
The AutoPilot 2.0 3D control system will also be demonstrated live in the outdoor area #B51404.
World Premiere: WPS 62i Placer/Spreader
Visitors to WOC 2020 in Las Vegas will be the first trade audience in the world to get a glimpse of Wirtgen’s new WPS 62i placer/spreader with two track units.
In the case of preplaced reinforcing steel, concrete must be supplied from the side. Placer/spreaders like the new WPS 62i/WPS 62 are perfect for this application. As the first machine in the Wirtgen paving train, the placer/spreader passes fresh concrete over pre-placed reinforcement in front of the slipform paver. A truck feeds the concrete from the side, which the placer/spreader then evenly distributes over the entire working surface.
The WPS 62i/WPS 62 is available with two different scraping units: in imperial units with working widths between 12 ft. and 24 ft. and in metric units with working widths from 4 m to 7.5 m. With both of them, the concrete can be laid up to 20 in. (500 mm) thick.
Due to its fully modular design with standard hydraulic quick-change couplings, the WPS 62i/WPS 62 can be easily reconfigured and quickly prepared for job site or for transport, which increases the machine’s uptime.
North American Debut: SP 124i Inset Slipform Paver
The Wirtgen SP 124i/SP 124 is the first slipform paver with a working width of up to 40 ft. (12 m) that Wirtgen has equipped with four steerable and slewing crawler units.
It's also available with an optional new hydraulic rotational drive system with a steering angle of up to 260 degrees. The additional maneuverability of the concrete paver allows the operator to quickly and flexibly adapt the machine to the conditions on the job site.
Its narrow profile and reduced track line allows to pave close to obstacles. In addition, the four crawler units can be switched to rotation mode at the push of a button. As a result, the SP 124i/SP 124 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 optimizing the transition from paving and decreasing downtime.
High Productivity Texture/Curing Machine
As the third machine in the Wirtgen paving train, the new TCM 180i/TCM 180 self-propelled texture/curing machine from Wirtgen guarantees the success of professional curing of concrete pavements.
It's equipped with an automatic spraying and brooming system and directly follows the slipform paver to create the desired surface texture. Finally, the spraying system applies a coating to the fresh concrete surface, preventing it from drying out prematurely. The modular design of the TCM 180i/TCM 180 supports working widths between 13 ft., 1 in. to 59 ft., 1 in. (4 m to 18 m).
North American Debut: Wirtgen AutoPilot 2.0
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, in the field, 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. In addition, it also eliminates the time-consuming measuring, mounting and removal of stringlines, making the entire operation faster and more cost-effective overall. Wirtgen offers the AutoPilot 2.0 for the SP 15/SP 15i and SP 25/SP 25i models. It is also possible to upgrade machines with the new system.
