ECI – Engineers Construction

ECI recently acquired a Trimble GCS900 Dual GPS machine automation system for our John Deere JD700J LGP track dozer.  It is currently in service at the Vermont Air National Guard Renewable Energy project and has recently worked on the Eastview Project.

“Look Dad, No Hands” – The system allows efficient and accurate grading without field layout and automatically controls the dozer blade using GPS technology.  The dual GPS receivers allow the best available control and accuracy.   The system uses a 3-D topographical model of the site and automatically computes the required slope and grade at the GPS locations of each end of the dozer blade.  The on-board computer and electric-over-hydraulic valves control the blade movement according the 3-D model.  An on-site base station allows for accuracy up to about 1 inch vertically and even better horizontally.

The Trimble GCS900 was purchased from Keystone Precision in April and the JD700J was purchased from Nortrax Equipment last year.
