The Trimble GCS900 3D Grade Control System can be installed on motor graders to put the site plan – design surfaces, grades and alignments – inside the cab.

Grading

• Measure the position and blade slope with the single GNSS antenna configuration
• Measure the exact position, very accurate cross slope and the heading of the blade with dual GNSS

GCS900 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

The Trimble GCS900 2D Grade Control System for motor graders is 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

GCS900 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
