Power Pavers has launched its new full-width, four-track concrete slipform paver, the Power Paver SF-3404. This latest model paves a maximum of 12 m and features telescoping endpans for 61 cm of width flexibility on each end. A heavy-duty plow, rigid paving pans and durable slew drives make the machine highly reliable and efficient.
Also new with the SF-3404 is an optional compact, fully-controlled dowel bar insertion (DBI) system. It is fitted 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 utilises a collision avoidance system to prevent centre tie bars and DBI from inserting at the same location.
To create the smoothest ride possible, Power Pavers said the SF-3404 is equipped with the industry’s longest oscillating correctional beam (OCB) for smoothing the slab’s surface after dowel bar insertion. The company has engineered a heavy-duty OCB that is 76 cm tall with a 61 cm 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.
An innovative 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 mould, DBI and OCB.
What’s more, the SF-3404 is designed to simplify operators’, finishers’ and mechanics’ jobs. It is equipped with Power Pavers’ signature SlipSmart control system for easy, highly configurable machine controls. All machine diagnostics are onboard, with no laptop required. The new system provides fault codes for everything on the paver, including the DBI. Common bolt sizes and colour-coded wiring throughout the machine keep maintenance simple.
