Topcon 3D-MC²

3D machine control that enables dozers to perform like graders! Topcon 3D-MC² enables faster performance up to twice the speed of standard Topcon 3D machine control for dozers. Using an unique MC² sensor that delivers position updates to the control box up to 100 times per second.

  • Increase the capacity of your dozer and do the job of a dozer and grader in one
  • Complete work faster with a system that is highly responsive to the blade and machine position even when working at speed
  • Flexible Topcon solutions enable you to swap or hire components from Aptella to get the right fit for every project

Twice as fast, twice as accurate

Topcon’s 3D-MC² shatters the final 3D automation production barrier – SPEED!

  • Increase speeds up to 200% over existing 3D Systems
  • Smoothness and grading accuracy comparable to graders
  • Same easy-to-use interface as previous Topcon Machine automation systems
  • Unmatched productivity that you will have to see to believe!

So revolutionary, it’s reshaping traditional machine roles

3D-MC² will drastically change the role your dozer plays on a typical site, in some cases eliminating the need for a grader. It will also allow you to make more efficient use of your dozer. Along with speed increases, 3D-MC² means fewer passes resulting in much more work done in less time.

Less time equals less fuel and less machine wear. Most importantly, it means your dozer can spend more time making you money in another location or on other jobs.

3D-MC² utilises Topcon’s GX-60 control box, GPS+ antenna, MC-R3 receiver and new 3D-MC² sensor and pairs them with advanced new controlling software to provide position updates up to 100 times per second.

The MC² sensor combines a gyro, compass and inertial sensor to measure the X, Y & Z position as well as the roll, pitch, yaw and acceleration of the dozer.
