The GOMACO four-track Commander III with IDBI attachment at work on a ramp project in Ohio slipforming 16 feet (4.9 m) wide and the IDBI attachment inserting 16 bars on 12 inch (305 mm) centers across the width of the new ramp’s transverse joints.
Ida Grove, Iowa – GOMACO’s exclusive G+® control system and its unlimited benefits will be showcased on the concrete pavers in their booth at World of Concrete 2014 in Las Vegas, Nevada, January 21-24. G+ is a control system that is both easy to learn and easy to operate. It expresses itself in easy to understand international icons and full script explanations. G+ operates in all the major languages of the world in either imperial or metric units. It has a lightning-fast processing speed and features two-way communications between paver accessories and the G+ controller. Its instant digital feedback combined with the tight closed-loop electronic and hydraulic control creates a G+ paving experience that is smooth, efficient, and accurate. There is nothing on the market that can compare, because G+ was designed by GOMACO’s in-house team from what was learned from years of experience in the field and from what was learned from concrete contractors.
One of the featured machines on display will be the GOMACO four-track Commander III with IDBI attachment. Both the paver and the IDBI are equipped with G+ controls to make start up and general paving each day faster and easier. The IDBI attachment is a new generation bar insertion system. The attachment is powered by its own C4.4, Tier 3, diesel Caterpillar® engine with 91 hp (68 kW) @ 2300 rpm. No power or hydraulics is needed from the Commander III’s engine. A CAN cable connects the IDBI’s controls to the G+ controller on the Commander III and allows the two systems to communicate. For example, when the Commander III stops and starts, the tamper bar and screed on the IDBI turn on and off automatically in coordination with the paver.
The self-contained, self-powered IDBI unit is capable of inserting transverse joint bars in pavements up to 16 feet (4.88 m) wide with the Commander III and wider widths on larger GOMACO pavers. The IDBI’s patented bar tray accommodates dowel bars ranging in size from one to 1.5 inches (25-38 mm) in diameter and from 18 to 24 inches (457-610 mm) in length. Adjustable height bar extractors allow quick and easy setup changes for the different bar sizes and insertion requirements. The IDBI’s insertion forks provide the industry standard for bar placement accuracy and have been designed to reduce the amount of scarring while vibration enhances the consolidation of concrete around each bar. After insertion, a tamper bar, unique oscillating straightedge, paving pan and stainless repair any scarring left over from the bar insertion process and apply the smooth GOMACO finish to the surface of the concrete.
The IDBI attachment features its own outriggers to aid in attaching the unit to the GOMACO 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 or detached from the paver. The outriggers have 48 inches (1219 mm) of stroke and are also used to raise the unit so a trailer can be backed underneath for transport.
G+ technology will be on display for high production curb and gutter, sidewalk, safety barrier, half-width and full-width paving, variable width paving, and paving with automatic dowel bar insertion. The newest updates for the GSI®, the GOMACO Smoothness Indicator tool for reading and achieving optimum rideability results, will be showcased. The job-proven C-450 bridge deck finisher will round out GOMACO’s display at World of Concrete 2014.
