An optional dowel bar inserter is available on the SF-3404.

An optional compact, fully controlled Dowel Bar Insertion system is equipped with a hydraulic floating floor to maintain integrity of the initial slab and improve reconsolidation around dowel bars after the insertion process. Each time the DBI runs, the carriage recalibrates with electric 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 centre tie bars and DBI from inserting at the same location.
A vibrator cruise control automatically adjusts the machine’s vibrators to maintain consistent speed despite fluctuations in oil viscosity or changes in concrete slump. An exclusive crown-distance compensation feature provides automated crown transitions between the mold, DBI, and OCB for super-elevations and intersections.
The SF-3404 features Power Pavers’ 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.
