MUNICH, Germany, April 15, 2013 /PRNewswire/ -- Trimble (NASDAQ:TRMB) today introduced version 2.1 of its 3D asphalt milling solution. The Trimble PCS900 Paving Control System for Milling Machines helps contractors mill a smoother and higher quality surface, reduce machine stoppage and minimize costly rework. Cutting-edge hot swap functionality in the Trimble SPS930 Universal Total Station maintains continuity and accuracy of milling operations without stopping the machine. System portability means contractors can use the system on multiple machines and jobsites, reaping a higher return on investment. Collectively, the elimination of stringline, reduced machine stoppage and rework can mean significantly improved productivity for the contractor using the PCS900 system. The announcement was made today at bauma 2013, the 30 th international fair for construction machinery, building material machines, mining machines, construction vehicles and construction equipment. Automatic Total Station Transition Enables Continuous Milling without Stops The Trimble SPS930 Universal Station provides a clear competitive advantage for the PCS900 Paving Control System. PCS900 uses the industry-leading Trimble SPS930 Universal Total Station and active targets to guide the milling drum to grade. Unique Trimble technology allows the system to hot swap, or automatically and instantly transition, to the next total station without stopping the machine to make a manual transition. By automatically maintaining the same tolerance between total stations, PCS900 also ensures a smoother milled surface at the transition point and reduces the need to re-mill spots along a long roadway project. Other 3D milling solutions require the mill to stop to make a manual transition each time a total station hand off is required, causing significant delay and reducing the smoothness of the milled surface. In a typical eight-hour shift, this machine stoppage and manual intervention can mean a productivity loss of up to 15 percent waiting for the equipment to be reestablished and recalibrated. The SPS930 also requires significantly fewer manual adjustments than fan laser based systems to maintain its high level of accuracy and deliver a smoother final surface.
