Gomaco will showcase its Xtreme line of concrete curb and gutter machines at CONEXPO 2020. The new pavers feature Xtreme steering capabilities with rotary-sensored slew drives on each track, Xtreme intelligence with smart hydraulic cylinders combined with G+ control, Xtreme hydraulic packages with independent hydraulic travel circuits to each track with G+ control on each individual track’s speed and smooth travel around radii, and Xtreme radius capabilities when paving with 3D guidance or stringline.
The Gomaco 3300 is a multi-application paver with a symmetrical design for right-side and left-side paving. It can also be equipped with a mold mounting kit to undermount a paving mold and be utilized as a transverse slipform paver. The 3300 will be displayed for the first time ever this show season with a 3.7m-wide undermounted transverse paving mold. The Gomaco G+ control system is behind the 3300’s transverse paving ability. The operator uses G+ controls to turn the 3300’s tracks 90 degrees into the transverse position and transverse paving configuration. In this configuration, the 3300 is capable of paving entrance/exit ramps, sidewalk/walking trails, dolly pads, polymer overlays, and more. When flat paving applications are complete, the contractor can drop the paving mold, press the button on the G+ digital control screen to put the 3300 into curb and gutter mode, and it becomes a fully functional curb and gutter machine capable of slipforming a large variety of applications including tight radii. Gomaco will also showcase a 3300 right-side mounted barrier mold to demonstrate the versatility of the 3300 model.
Other Xtreme curb and gutter machines capable of slipforming tight radii are the Xtreme GT-3600 and Commander IIIx. The Xtreme Commander IIIx and GT-3600 are the curb and gutter machines contractors rely on for high-production, maximum quality curb and gutter, barrier, parapet, sidewalk, recreational path, small canal, water channel, and more, multi-application slipform machines. Both the machines can slipform a 610mm radius. Rotary-sensored slew drives and smart hydraulic cylinders allow the G+ control system to determine the position of all three tracks of the curb and gutter machines to make steering adjustments. Independent hydraulic travel circuits to each track allow G+ to control each track’s speed through the radius. Both machines also feature the Gomaco three-sensor radius system when paving on stringline. The radius system allows the lead steering wand to leave the stringline and switch reference to the second sensor for traveling around the tight radius. The Xtreme turning capabilities also make the machines suitable for navigating around job-site obstacles, getting on and off stringline and paving passes, and loading and unloading the machine for transport.
Gomaco’s curb and gutter machine line up at CONEXPO-CON-AGG 2020 will include the GT-3200, Gomaco’s compact curb and gutter paver. The curb and gutter machines on display will feature the different stringline and stringless paving options from Topcon, Leica Geosystems and Trimble.
