February 19, 2009

thThe Trimble Grade Control Receiver (GCR) is a cost-effective laser-based machine control system that can significantly improve the productivity and accuracy of grading equipment by as much as 50 percent. Used primarily for finishing grade on sites and for foundations, the GCR family of laser receivers is easy to learn. With minimal training, even inexperienced operators are able to get up to speed in no time at all. GCR is ideal for a variety of machines, including dozers, drag boxes, scrapers, trenchers, skid steer attachments and small motor graders. The system consists of the GCR laser receiver mounted on a rigid mast that is mounted on the machine”s blade and a laser transmitter set up on the job site. And with the addition of a hydraulic control valve to the machine, the GCR valve control capability enables it to provide complete proportional blade control relative to the laser reference.
