3D Grade Control for Motor Graders
Trimble 3D grade control can be installed on motor graders to put the site plan – design surfaces, grades and alignments – inside the cab.
Grading
- Accurately measure the position and blade slope with the single GNSS antenna configuration
- Measure the exact position, cross slope and the heading of the blade with dual GNSS
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
2D Grade Control for Motor Graders
2D grade control systems from Trimble are an excellent first investment for contractors new to construction technology.
Grading
- Measure the lift and tilt of the blade with a single laser and laser receiver
- Measure the slope of the blade by adding another laser receiver or a slope sensor
- Get to grade more accurately and quickly with in-cab elevation and slope guidance
- Upgrade to a 3D grade control system as your organization grows
Finished Grade
- Achieve tight tolerances and a smooth finished grade with precise vertical guidance.
- Calculate the cross-slope of the blade using two angle sensors and a rotation sensor
- Add a laser receiver or a sonic tracer to measure elevation
- Trace stringline, previous pass, or curb and gutter with a sonic tracer
