Gomaco is building on the success of the GP360, the industry’s first combination concrete slipform paver and placer/spreader on two tracks. This year at Conexpo, Gomaco unveiled the new GP460 for wider width operations. As a placer/spreader with a 1,524 mm belt, the GP460 will accommodate widths up to 15.2 m. As a concrete slipform paver, the machine will pave widths up to 12.2 m.
It is built on the framework of the Gomaco two-track GP4 slipform paver with the ability to convert the prime mover into a concrete placer/spreader. The prime mover is equipped with vibrator circuits for paving and auger drive circuits for placing. Controlling the new technology is made possible with the Gomaco-exclusive G+ digital control system. G+ seamlessly handles the controls conversion needed for each application while also bringing onboard machine-to-machine (M2M) communication, sonic sensors, 3D machine guidance, and more.
The Gomaco GP460 is powered by a Caterpillar C7.1 turbocharged diesel engine to efficiently drive the conveyor belt and distribute concrete across the grade. The high-volume, 1,524 mm conveyor belt can be mounted on either the left or right side, depending on jobsite conditions and the location of the haul road. It has a discharge speed of up to 150 m/min for fast and efficient concrete placement. A controllable material deflector directs the flow of concrete at the discharge end of the conveyor for placement accuracy. A dual-drive auger system moves the material to the centre or outer areas and across the strike-off.
The GP460 is available with an optional sonic sensor system to monitor the concrete depth as it is placed. Information from the sonic sensors is utilised by the G+ control system on the paver using M2M communication to provide an optimum and consistent head of concrete in front of the paver.
