GOMACO’s GT-3600 with G+® Controller and Topcon mmGPS 3D for Tight Radii Curb and Gutter Island Paving


The GOMACO GT-3600 with Topcon mmGPS 3D machine guidance slipforms tight radii curb and gutter on a parking lot project.

Ida Grove, Iowa – Contractors specializing in tight radii island paving and other parking lot challenges now have some powerful options for 3D slipforming. The GOMACO GT-3600 curb and gutter machine with 3D guidance quickly and accurately slipforms tight radii curb and gutter in parking lots. The GOMACO GT-3600 with G+® controller and Topcon mmGPS will be featured at World of Concrete 2015 in their booth in the Central Hall, #C5146, of the Las Vegas Convention Center in Las Vegas, Nevada, February 3-6, 2015.

The GT-3600 with All-Track Steering (ATS) is built for turning tight radii, as tight as 24 inches (610 mm). The Topcon 3D system uses algorithms for tight radii that simulate how steer sensors would work on stringline and automatically adjusts in and out of a radius. The software also has definable parameters to help sharpen cornering, as well as transitions in the entry and exit of the radius to provide smoother results. The 3D system is able to anticipate and adjust to the radius accordingly, because it has the project model loaded into its computer with the upcoming design elements.

The GT-3600 features a 15 foot (4.6 m) long, 24 inch (610 mm) wide charging conveyor and a hopper designed for extra concrete capacity. Fully loading the conveyor and hopper before entering the radius allows you to complete the radius without having to wait for another concrete delivery. The mold on the GT-3600 is positioned to assure perfect placement of the concrete through the radius and the operator’s platform offers ultimate visibility of the entire slipforming operation.

The three-track GT-3600 is a multi-application trimmer/slipform paver with job-proven results throughout the world. It is versatile and its applications include curb and gutter, tight radii, cul-de-sacs, safety barriers, bridge parapets, sidewalks, recreational paths, and flat slabs up to 10 feet (3 m) wide. It has one of the fastest tracking speeds in the industry for quickly moving around large projects. The travel speed is up to 125 feet per minute (38 mpm), and the low speed provides the smooth crawl necessary for slipforming concrete.

Discover the advantages of a 3D guidance system on a GOMACO paver or curb and gutter machine. All of the paver’s in the GOMACO booth will feature a 2D or 3D guidance system. GOMACO’s G+ control system has an entire library of sensor capabilities for controlling slope, grade and steer with set-up configurations for any project requirement. The G+ control system seamlessly integrates with the major 3D guidance systems, including Topcon, Leica Geosystems, and Trimble. It’s as simple as connecting with G+ Connect. GOMACO’s 3D team will be at World of Concrete ready to discuss 3D paving applications.
