The GP348 is a high-production concrete placer/spreader up to 36 feet wide with a 48-inch belt and a top-of-the-line four-track GP3 for slipform paving up to 30 feet wide.
It's built on the framework of the GOMACO four-track GP3 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 on board Machine-to-Machine (M2M) communication, sonic sensors, 3D machine guidance, and more. Rotary-sensored slew drives on its leg pivots work seamlessly with the G+ control system. Operators can automate transitions from transport to paving mode, dramatically reducing setup time and improving efficiency. Its four-track design enhances stability and on-site maneuverability, while its compact transport footprint allows it the capability to be hauled on a single semi-tractor trailer (either as a placer or paver), minimizing downtime between pours.
The GOMACO GP348 is powered by a Caterpillar C7.1 turbocharged diesel engine, which efficiently drives the conveyor belt and distributes concrete across the grade. The high-volume, 48 inch (1219 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 491.5 feet 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 GP348 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.
