Wirtgen SP 80i concrete slipform paver has a maximum paving width of 26 feet.
The accompanying photos illustrate the versatility of the Wirtgen Series SP 80i slipform paver, which can work in a four-track inset configuration (SP 84i), two-track inset configuration (SP 82i), three-track offset configuration (SP 81i), or as an option for the latter, a four-track offset configuration. Wirtgen hastens to add, however, that the modular design of the SP 80i platform allows “any model to be reconfigured into another with the right options.” The “i” in the model designations, says the company, indicates that the machines have “intelligent” power and emissions control systems.

The SP 80i platform, says Wirtgen, can be used with options such as a dowel-bar and tie-bar inserter, finishing beam, and “super smoother.” Machine control can be stringline based or “stringless,” says Wirtgen, and either method yields “unprecedented accuracy, which leads to higher production and less hand finishing.”
According to Wirtgen, the fully modular inset-mold system permits paving concrete slabs with central crown from 12 to 26 feet wide. Concrete can be distributed either with a spreading plow or spreading auger, and the machine can use up to 24 vibrators.
In its offset configuration, the Series SP 80i can accommodate a range of poured-in-place profiles, with standard heights of 7.5 feet and standard widths of up to 10 feet. Concrete feed can be handled via a high-performance belt conveyor or auger conveyor. The offset mold suspension, says Wirtgen, is suitable for mounting on either side of the machine.
The Series SP 80i provides four steering options—crab, coordinated, back-straight and rotate—and the machines’ Eco-Mode system automatically matches engine output to the operating situation. In addition, Wirtgen’s AutoPilot stringless control system is available for poured-in-place concrete profiles, such as curbs, safety barriers and slabs.
The W 200Hi milling machine has a hydraulically driven drum assembly that can be displaced 15.75 inches to the right or left.
The company’s largest cold mill, the W 250i, has a maximum power rating of 991 horsepower and wide conveyor slewing angles to make the milling process more efficient.
