The new Wirtgen SP 80i concrete slipform paver was introduced to North America at World of Concrete 2013, Feb. 5 to 8 in Las Vegas.
The SP 80i’s modular design permits different configurations. The SP 80i can be set up as an offset SP 81i for very large sections, or as an inset paver with two tracks (SP 82i) or four tracks (SP 84i). However, the modular design of the SP 80i platform means any model can be reconfigured into another with the right options.
The “i” designates these pavers as having “intelligent” power and emissions control systems.
The new SP 80i offers dowel-and-tie bar inserters, finishing beam, super smoother and many other options. It can be controlled either with stringline or stringless.
The benefits of the SP 80i include increased accuracy, which leads to higher production with less hand finishing; machine flexibility to meet changing job site requirements; ease of use with a quick learning curve; and ease of troubleshooting, according to the manufacturer.
Its fully modular inset mold system permits paving of concrete slabs with central crown from 12 to 26 ft. (3.6 to 7.9 m) wide. Concrete can be spread by spreading plow or spreading auger. The pavers can use up to 24 electric or hydraulic vibrators.
Its highly flexible offset mold system permits a wide choice of poured-in-place concrete profiles, with standard heights of 7.5 ft. (2.3 m) or standard widths of up to 10 ft. (3 m). Feeding of concrete is via high performance belt conveyor or auger conveyor, with various adjustment options.
