The SF-3404 paves a maximum of 40 ft. and features telescoping endpans for 2 ft. of width flexibility on each end.
Power Pavers announced the launch of the industry’s newest full-width, four-track concrete slipform paver: the Power Paver SF-3404.
The SF-3404 is built with decades of knowledge and technological advancements, delivering contractors the smoothest ride possible, saving valuable time and providing complete visibility around the machine, the manufacturer said.
It paves a maximum of 40 ft. and features telescoping endpans for 2 ft. of width flexibility on each end. In addition, a heavy-duty plow, rigid paving pans and durable slew drives make the SF-3404 highly reliable and efficient.
Also new with the SF-3404 is an optional compact, fully-controlled dowel bar insertion (DBI) system. It is equipped with a hydraulic floating floor to maintain the integrity of the initial slab and improve reconsolidation around dowel bars after the insertion process. Each time the DBI runs, the carriage recalibrates with electronic sensors to ensure the floor is exactly where it should be. In addition, the DBI is split to allow for accurate crowning and bar placement. Each bar is held and guided into the concrete to prevent skewing, even while crowning.
When running DBI, the machine utilizes a collision avoidance system to prevent center tie bars and DBI from inserting at the same location.
To create the smoothest ride possible, the SF-3404 is equipped with the industry’s longest oscillating correctional beam (OCB) for smoothing the slab’s surface after dowel bar insertion. Power Pavers engineered a unique, heavy-duty OCB that is 30 in. tall with a 24 in. finishing length for full coverage over the dowel insertion void. The OCB corrects any surface imperfections with ease. For transportation, the DBI, OCB, OCB wiper and final finisher are contained in a single assembly.
A vibrator cruise control automatically adjusts the machine’s vibrators to maintain consistent speed despite fluctuations in oil viscosity or changes in concrete slump. For super-elevations and intersections, an exclusive crown-distance compensation feature provides automated crown transitions between the mold, DBI and OCB, according to the manufacturer.
As with other Power Pavers, the SF-3404 is designed with simplicity in mind. The machine features numerous other thoughtful details to simplify operators, finishers and mechanics’ jobs. It is equipped with Power Pavers’ signature SlipSmart control system for simple, highly configurable machine controls.
All machine diagnostics are onboard, with no laptop required. The new system provides fault codes for everything on the machine, including the DBI. Common bolt sizes and color-coded wiring throughout the machine keep maintenance simple.
