Trimble Placer/Spreader Machine Control Offers Improved Paving Productivity, Less Waste

Trimble’s PCS900 Paving Control System version 2.20 is designed for GOMACO and Guntert & Zimmerman placer/spreader machines. The new version of PCS900 further automates the paving train by enabling contractors to use GNSS-based positioning, in conjunction with a base station, to steer the machine and control the machine’s elevation according to a 3D model. This can significantly improve paving productivity and reduce material waste on concrete road and airport surfaces.

With the availability of GNSS-based 3D machine control for placer/spreaders, paving contractors can move their Trimble GCS900 Grade Control System display, radio, sensors and GNSS receivers between even more machines in their fleet. By using Trimble grade-control components on their placer/spreader, users can realize a faster return on their investment for Trimble technology, the company said.

In addition, factory-fit integration between GOMACO and Guntert & Zimmerman placer/spreaders and the Trimble PCS900 system gives contractors an easy-to-learn, seamless paving control solution, Trimble said. Operators can make any necessary adjustments to machine guidance with the onboard 2D system they are familiar with, lowering the training time needed to learn a new system.

Without machine control, a concrete placer/spreader is controlled manually or by two stringlines, one on each side of the lane being paved. Using the PCS900 system, time-consuming labor spent setting up these stringlines can be eliminated. The Trimble PCS900 uses GNSS-based positioning to keep the placer/spreader on the target alignment, design and slope so contractors can spread material faster and more efficiently while reducing labor costs.

The Trimble PCS900 system version 2.20 is currently available for GOMACO placer/spreader machines with G22 or G+ machine controllers through GOMACO in North America. PCS900 version 2.20 for the Guntert & Zimmerman placer/spreader machines running the EGON machine control system is available through Trimble’s worldwide SITECH® Technology Dealer Channel.
