Gomaco is building on the success of the GP360 and GP460, the industry’s first combination concrete slipform pavers and placer/spreaders on two tracks. This year at Conexpo 2026, the company introduced the GP348 four-track for enhanced jobsite and job-to-job mobility. As a placer/spreader with a 1,219-mm belt, the machine can place at widths up to 11 m. As a concrete slipform paver, it can pave widths up to 9.1 m.
The GP348 is 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 enabled by Gomaco’s G+ digital control system, which manages the control conversion needed for each application while also bringing on board machine-to-machine (M2M) communication, sonic sensors, 3D machine guidance, and more.
Rotary-censored slew drives on the leg pivots work seamlessly with the G+ control system. Operators can automate transitions from transport to paving mode, significantly reducing setup time and improving efficiency. The four-track design enhances stability and on-site manoeuvrability, while the compact transport footprint allows the machine to be hauled on a single semi-tractor trailer (either as a placer or paver), minimising 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. This high-volume, 1,219-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.
In addition, 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 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.
