GCS21

Grade Control System

Flexible, modular laser-based machine control system

The flexible Trimble GCS21 Grade Control System is an advanced laser-based machine control solution for the earthmoving industry.

The GCS21 modular design and Controller Area Network (CAN) capability is the foundation of Trimble's next generation of machine control solutions. The CAN based system allows for easy configuration and expandability to meet changing grade control requirements both today and in the future. The system offers a wide range of configurations from a self-contained, battery operated grade display system to full automatic grade control system.

The GCS21 system consists of  the LR21 and can be used as a stand alone machine guidance display, or as a component of the full automatic grade control system. The LR21 is easily and quickly installed on a manual or electric mast on the machine.

As a full automatic system the laser receiver is connected to the machine's hydraulics using the SCB21 Single Control Box and the SRB21 Single Remote Box. The signals from the laser receiver are used to control a proportional hydraulic valve for blade correction, allowing operators to grade faster and more accurately.

The GCS21 grade control system is ideal for contractors and machine operators who require the flexibility to customize the system to fit the specific needs of each job application. Key features and benefits include:

• flexible configurable machine control system designed to meet all your grade-control requirements now and in the future
• Controller Area Network (CAN) expandability meets changing jobsite applications.
• digital linear laser receiver and proportional valve control ensures maximum productivity and accuracy
• no grade checkers required, cutting cost, eliminating communication errors, rework and idle machine time
• immediate return on investment as your operators get to grade faster with greater accuracy
• Auto Benching of blade elevation reduces downtime and maintains precise material control without leaving the cab of the machine
• 30 – 55% productivity improvement and 25 – 70% accuracy improvement
• local and fast equipment service and support
