Machine Control Systems - Grade Control
The KOREC team work with the extensive range of Trimble Grade Control Systems. From lasers to the highest performing Total Stations and GPS these rugged systems are easy to use, fully upgradable and flexible enough to meet a wide range of applications. Trimble’s 3D systems enable operators to precisely grade complex sites up to an accuracy of five millimetres. This precision reduces rework, increases productivity and minimises the use of expensive materials – all increasing your profitability.
3D Machine Control and Guidance Systems
The Trimble GCS900 System offers full 3D Machine Control.

Trimble GCS900 Grade Control System
3D Grade Control System available in a range of configurations.

Trimble CCS900 Compaction Control System
The Trimble® CCS900 Compaction Control System is the first satellite-based positioning solution to offer contractors the ability to compact surface material to a target density and check finished grade accuracy in the same process.
Conventional Grade Control Systems
Conventional systems begin with a single laser receiver system, and progress to combinations of laser receivers, sonic tracers, angle sensors and rotation sensors.

Trimble GCS300 Grade Control System
Affordable single control system, suited primarily to dozers.

Trimble GCS400 Grade Control System
Dual Elevation or Elevation and Blade Slope Control.

Trimble GCS500 Grade Control System
The GCS500 Grade Control System is a cross-slope control system designed to be used on motor graders for fine grading work.

Trimble GCS600 Grade Control System
The GCS600 Grade Control System is a highly flexible, cross slope and elevation control system designed to be used on motor graders for fine grading work.

Trimble GCS600 Grade Control System for Excavators
The Trimble® GCS600 Grade Control System for Excavators is a highly flexible laser-based system designed for excavation, trenching, grading and profile work.
Laser-based Display Systems
Using a grade display receiver guides the operator to the desired elevation or depth without a grade checker, you improve accuracy and increase profits.
