GOMACO’s New Independent IDBI Attachment for a New Decade of Concrete Paving

 

Ida Grove, Iowa -- Almost three decades have passed since GOMACO Corporation revolutionized the concrete paving industry with the introduction of the GOMACO system for putting dowel bars into a concrete slab during the paving process. The GOMACO IDBI has been proven and accepted around the world for accuracy in bar placement location, productivity and meeting rideability specifications. Now, in 2010, GOMACO will once again create a revolution with the international introduction of the independent IDBI attachment. It will be on display for the first time to the worldwide market at Bauma 2010, in the GOMACO stand located in Open Air Area F12, Stand #1210/3 at the New Munich Trade Fair Centre in Munich, Germany.

The new IDBI attachment is an independent unit providing dowel bar insertion behind a paver to form the transverse joint. The IDBI attachment is a new generation bar insertion system. The attachment is powered by its own C4.4, Tier 3, diesel Caterpillar® engine. No power or hydraulics is needed from the paver’s engine. A CAN cable connects the IDBI’s controls to the controller on the paver and allows the two systems to communicate. For example, when the GOMACO paver stops and starts, the tamper bar and screed on the IDBI turn on and off automatically in coordination with the paver. GOMACO's engineers have designed a bar insertion concept and created an independent attachment that is self-contained and self-powered. The new design features a new IDBI tray that is stronger, more compact and makes width changes easier. New adjustable-height bar extractors allow contractors to quickly and easily change the setup for different bar sizes for insertion requirements.

The IDBI controls have all been designed in-house by GOMACO controls engineers. Its new GOMACO G+ control system features the same graphical display as the G22 controller, with easy to learn and easy to understand controls. The IDBI information is presented in full color, commands are presented in full text, and it is able to operate in two or more languages, by customer’s choice. It offers the choice of metric or imperial measurements. The new IDBI control system also offers troubleshooting capabilities and other features that will make start up and general paving each day fast and easy.

The new independent IDBI attachment features it own outriggers to aid in attaching the unit to the paver and also for loading and unloading the unit for transporting. The outriggers can be hydraulically lowered and placed on the ground to support the full weight of the IDBI as it is attached to or detached from the paver. The outriggers on the attachment have 1194 mm (47 in) of stroke and are also used to raise the unit so a trailer can be backed underneath for transport.

The IDBI attachment is available for all GOMACO slipform pavers, from paving lanes or shoulders as narrow as three meters (10 ft) wide with the four-track Commander III, to expressways as wide as 15.2 meters (50 ft) with the GOMACO GP-4000.
