Contractors specializing in tight radii island paving and other parking lot challenges now have some powerful options for 3D slipforming.
The GT-3600 with All-Track Steering (ATS) is built for turning tight radii, as tight as 24 inches. 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 long, 24 inch 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 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.
