Topcon 3D-MC2 for Motor Graders

March 23, 2011

Billed as the world's first 3D-MC2 technology for motor graders, the system allows a grader to operate at speeds well above those on other 3D machines, and with tighter tolerances. The technology was introduced in 2008 for dozers, and now it will enable graders to not only speed up grading operations, but also provide pitch compensation so the operator can roll the blade to adjust the cutting edge to various materials conditions. The control system senses changes in the cutting edge position and is said to make corrections up to 100 times per second, providing excellent stability and smoothness while finish grading. According to the company, by using 3D-MC2 on a grader with constant material conditions, it is possible to finish up to 750,000 square feet per day or more (compared to a typical day of finishing from 40,000 to 160,000 square feet a day).
