New stringless 3D paving control

2122 Trimble and 218 Gomaco announced the release of a new stringless 3D paving control solution with CAN-bus integration into Gomaco slipform pavers at Conexpo 2014. Using field-proven Trimble total stations, on-machine positioning sensors and office software, the new Trimble PCS900 Paving Control System allows contractors to pave an accurate and consistent concrete surface with increased productivity and yield. The solution will be sold through Gomaco in North America on new and existing GHP-2800 four-track slipform pavers, with additional paver models expected to follow.

Leveraging the Gomaco expertise in concrete paving operations with Trimble innovation and expertise in precision machine control, concrete contractors can see increased efficiency and maximised yields from their concrete paving operations.

Integration between the Gomaco paver and the Trimble paving control system gives operators real-time 6-axis control over the pan and the ability to use a 3D design model to control grade and slope. The time and cost of stringlines is completely eliminated, allowing projects to start sooner and maintain smoother haul operations without the need to drive around stringlines.

Trimble PCS900 uses automatic steering and 6-axis control of the pan to keep the paver on the target alignment, design and slope. The Trimble SPS930 Universal total Station and Hot Swap technology offer a significant advantage by making total station transitions faster and less dependent on manual intervention from the operator. The system will “hot swap”, or automatically and instantly transition, to the next total station without stopping the machine to make a manual transition. While doing so, it also automatically maintains the same tolerance between total stations, ensuring a smooth surface at the transition point.
