IDBI Dowel Bar Inserter

IDBI Dowel Bar Inserter Information

The Worldwide Authority In Bar Placement
GOMACO’s IDBI Dowel Bar Inserter is the industry’s most productive and compact system for the automatic insertion of dowel bars across a finished concrete slab. It is designed for installation onto a two- or four-track paver. The paving operation, bar insertion and finishing operations are all combined into one compact unit.

The IDBI is GOMACO’s patented system of putting dowel bars into a concrete slab during the paving process. Our engineers have designed a complete system that is accurate and user-friendly, while assuring you, our customer, has a piece of equipment that can be adjusted to provide exacting tolerances for any job specification.

The IDBI is far superior to others on the market for accuracy in bar placement location, productivity and meeting rideability specifications.

Over two decades, we have sent out field representatives and engineering and research teams to the job sites to study our dowel bar insertion process and make improvements to assure our system continues to be the most advanced and operator-friendly dowel placement method in the industry. Inspectors and civil engineers expect accuracy in the bar location in the slab and contractors wanted the process incorporated in the paver without huge transport and setup demands.

The insertion forks on the new IDBI have been designed to provide the industry standard in bar placement accuracy. The fork design also reduces the amount of scarring on insertion and vibration consolidates and closes material around the inserted bars. A tamper bar, unique oscillating straightedge, paving pan and stainless repair the scarring in the slab.

The computer control system GOMACO has developed for the IDBI manages all the systems in an easy to understand display. The computer controls the timing and operations of the IDBI functions, including sending the trolley, positioning the IDBI in standby, and activation of the IDBI system for bar insertion.

Presetting and adjusting joint spacing for IDBI activation is easy to understand and simple to program. Bar inserters for longitudinal joints can be programmed and controlled through this same system. The operator has to know exactly where the IDBI is during the paving process and the screen for the IDBI menu was designed with that in mind.

Performing self-diagnostics and all programming is a simple task on the touch-screen system.

GOMACO has designed special software to allow smooth transitions from crown to flat slope and vice versa. The Power Transition Adjuster (PTA) in the front pan, the IDBI and the finishing pan are all synchronized to make the necessary adjustments as they reach specific stations in the transition.

GOMACO holds domestic and European patents on the bar-loading trolley, computerization program, and the IDBI.

GOMACO has proven its commitment to the automatic insertion of dowel bars through our years of testing and research. That is why GOMACO is the leader in the IDBI system and we will continue to bring our customers the best innovations in concrete construction equipment.
