Trimble’s 2D excavator system, the GCSFlex grade control system for excavators, gives you everything you need to do precision excavation in a kit no bigger than a suitcase. Installation can be done by the contractor in a couple of hours with no welding or drilling. The system can also be easily transferred to other machines or rental machines. Sensors on the boom feed position and angle information to a display screen you mount in the cab. Once you’re set up with your installation you can bench your bucket once and then proceed to dig guided by displays on the screen to accuracies of under one inch. This eliminates having a man in the trench checking measurements or rework due to over or under-excavating to the target. The GCSFlex also allows you to upgrade to more sophisticated systems without starting over with a completely new system.
