The Commander III four-track concrete slipform paver now offers the new IDBI attachment for dowel bar insertion. The attachment is an independent unit providing dowel bar insertion behind a paver. It enables the paver to insert transverse joint dowel bars in pavements up to 16 ft. wide. It is powered by its own Caterpillar C4.4 Tier III diesel engine rated at 91 hp at 2,300 rpm. Once the attachment is bolted to the framework, the only connection is the CAN cable for machine automation. The G+ control system features the same graphical display as the G22 controller, with easy to learn and easy to understand controls. Adjustable-height bar extractors allow for quick, easy setup change for different bar sizes for insertion requirements. The outriggers on the attachment have 48 in. of stroke and are also used to raise the unit so a trailer can be backed underneath for transport.
