GCS900 2D / 3D for Graders

Trimble offers the heavy and highway contractor the broadest range of Grade Control Systems in the industry. From 2D laser or sonic based to 3D GNSS or Total Station based, Trimble systems are rugged, easy to use, fully upgradeable and portable, and flexible enough to meet a wide range of application and jobsite requirements.

The Trimble® GCS900 Grade Control System with automatic blade control maximizes motor grader performance. Whether grading simple pads and slopes or complex design surfaces and alignments the operator can get to grade at high speeds, without sacrificing grade control accuracy or quality of the final graded surface.

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.

• 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

• Achieve finished grade to millimetre 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.

• 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

• 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
