With its debut at CONEXPO-CON/AGG 2023, the GOMACO GP460 is the industry’s first combination concrete slipform paver and placer/spreader on two tracks. Designed for wider-width operations, as a placer/spreader with a 60-in. (1524 mm) belt, the GP460 will accommodate widths up to 50 ft. (15.2 m) wide. As a concrete slipform paver, the GP460 will pave widths up to 40 ft. (12.2 m) wide.
It's 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, 60-in. (1524 mm) conveyor belt can be mounted on either the left or right side, depending on job-site conditions and the location of the haul road. It has a discharge speed of up to 492.5 ft. per minute (150 mpm) 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 center 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 utilized 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.
