Trimble GCS900 on a Motor Grader with Single GPS

The Trimble® GCS900 Grade Control System with the single GPS option can be installed on motor graders for a wide range of earthmoving applications. The Trimble GCS900 on a motor grader with single GPS is a full 3D control system that puts the site plan - design surfaces, grades and alignments - inside the cab.

Using the single GPS antenna configuration, the position and blade slope is measured.

The on-board computer uses this position information, and compares it to the design elevation to compute cut or fill to grade. This information displays on the Control Box screen in plan, profile, cross-section view, or text. The cut/fill data is also used to drive the valves for automatic blade control.

Additionally, the cut/fill data is passed to the GCS900 lightbars, providing additional visual guidance to the operator for up/down to grade and right/left to a defined alignment. The GCS900 on a motor grader can be operated in either indicate or automatic mode.

The Trimble GCS900 on a motor grader with Single GPS is ideal for contractors who require a cost-effective, 3D grade control solution for site preparation and bulk earthworks. The Single GPS option is easily upgradeable to the GCS900 for motor graders with Dual GPS or ATS systems as economic or jobsite requirements change. GPS-based Grade Control Systems are ideal for larger site projects and long-term, multi-phase projects.

Using the Trimble GCS900 with single GPS on a motor grader allows contractors to significantly improve their productivity and profitability.
