SITECH Trimble 3D Grade Controls for ScrapersThe Trimble GCS900 Grade Control System installed on a scraper is ideal for mass excavation applications.

  • Track GPS, GLONASS and Galileo signals
  • Display design information and live cut/fill indications in the cab
  • Excavate in a safer, stakeless environment.
  • Monitor avoidance zones in real-time
  • Collect as-built data as the machine cuts to grade
  • Keep tighter control over safety issues and see precisely where dirt is being moved on site


GCS900 for scrapers is useful for:

  • Land reclamation projects
  • Dam and reservoir construction
  • New infrastructure projects
  • Landfills and waste deposits


  • SINGLE GNSS – Measures the position and slope of the blade and compares that to design data for rough grading and mass excavation on complex design surfaces
  • DUAL GNSS – Measures the exact position, cross slope and heading of the blade for fine and rough grading or mass excavation on steep slopes and complex design surfaces
