Grade Control For Motor Graders

Finished grade with fewer passes. Place material faster and with millimeter accuracy. With GCS900 on your grader you’ll keep costs to a minimum and realize better profits.

The Trimble Grade Control System can be installed on motor graders to put the site plan – design surfaces, grades and alignments – inside the cab.

Finished Grade

  • Achieve finished grade to millimeter accuracy with fewer passes
  • Place finished grade materials more accurately and in a shorter time period, keeping material costs to a minimum and realizing better profits

Applications

Used with a total station, single or dual GNSS receivers, 3D is well suited for grading and fine grading applications such as:

  • Material spreading
  • Highway and railway construction
  • Airport construction
  • Concrete pours and slab placement
  • Residential and commercial site construction

Configurations

  • DUAL GNSS – Measures the exact position, cross slope and heading of the blade for rough grading and mass excavation on steep slopes and complex design surfaces
  • SINGLE OR DUAL GNSS WITH LASER AUGMENTATION – Single and dual GNSS systems enhanced with laser augmentation to improve vertical accuracy for high accuracy guidance to complex design surfaces such as super-elevation grading from rough through finished grade work
  • UNIVERSAL TOTAL STATIONS – Total station based system for extreme accuracy for lift and layer control, material monitoring, or where GNSS is not the ideal solution because of overhead obstructions

The Trimble® 2D Grade Control System for motor graders is an excellent first investment for contractors new to construction technology.

Finished Grade

  • Achieve tight tolerances and smooth finished grade
  • Calculate the cross-slope of the blade using two angle sensors and a rotation sensor
  • Add a laser reciever or sonic tracer to measure elevation
  • Trace stringline, previous passes, or curb and gutter with use of a sonic tracer
  • Upgrade to a 3D grade control system as your organization grows

Applications

Using the 2D system with a sonic sensor or a grade laser to improve the efficiency and productivity of your motor grader on projects such as:

  • Road and highway projects
  • Land reclamation projects
  • Dam and reservoir construction
  • New infrastructure projects

Configurations

  • CROSS-SLOPE ONLY – Cross-slope control systems to be used on motor graders for fine grading work for road maintenance, ditches and slope work
  • SINGLE ELEVATION PLUS CROSS-SLOPE – Single control system uses a laser or sonic receiver to control the lift of the machine blade and the cross-slope for flat, slope work, and finished grading
  • DUAL ELEVATION – Dual control system that uses two laser or sonic receivers for higher accuracy lift control. Blade edge can be controlled independently or linked
