Trimble recently introduced a portfolio of laser-based machine display and control systems for grading and excavating applications. The new Spectra Precision Laser machine systems are highly flexible, extremely rugged and can be used on a wide range of machines, including dozers, backhoes, scrapers, skid steers and excavators. On a dozer, the system can be upgraded for automatic blade control providing even greater productivity gains. The Spectra Precision Laser grade control systems give the operator visual guidance for the cutting edge of the blade or bucket. This capability helps operators get to grade faster with increased accuracy. The Spectra Precision Laser family of machine systems includes three new laser receivers and a control box: the Spectra Precision Laser LR30 Laser Receiver, LR50 Laser Receiver, and LR60 Laser Receiver. Additionally, for automatic blade control, contractors can add on the Spectra Precision Laser CB25 Control Box.
