GOMACO curb and gutter machines designed for tight turns

GOMACO’s Xtreme line of concrete curb and gutter machines feature enhanced steering capabilities with rotary-sensored slew drives on each track, as well as the company’s Xtreme intelligence with smart hydraulic cylinders combined with G+ control.
The line, which was introduced in Las Vegas, US, at ConExpo in March, also offers GOMACO’s Xtreme hydraulic packages with independent hydraulic travel circuits to each track with G+ control on each individual track’s speed as well as smooth travel around radii.
The company states machines offer its 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 utilised as a transverse slipform paver.
The GOMACO G+ control system is responsible for the 3300’s transverse paving ability, the company states. 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 operator 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, according to a press release.
The Xtreme Commander IIIx and GT-3600 are curb and gutter machines designed for high-production, maximum-quality curb and gutter, barrier, parapet, sidewalk, recreational path, small canal, water channel, and more. Both can slipform a 610-mm (24-in.) radius.
Rotary-sensored slew drives and smart hydraulic cylinders allow the G+ control system to know the position of all three tracks of the curb and gutter machines to make as-needed 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 enable them to navigate around job site obstacles.
The GT-3200, GOMACO’s compact curb and gutter paver, features different stringline and stringless paving options from Topcon, Leica Geosystems and Trimble.
