Welcome GPS

Welcome to the World of GPS (Global Positioning System) and the newest edition to the Elmer’s Crane & Dozer Family.  The GCS900 (Grade Control System 3D Automatic Control) from Trimble was installed on a D6R Dozer in Early June. The GCS900 puts design surfaces, grades and alignments inside the cab.  You can operate the system in a completely stakeless environment and grade to an accuracy of 0.1 ft.  Translation to English: “It takes what the Engineers & Surveyors see on a computer screen and turns it into a hands on product out in the real world.” 

 

How it works

1)  A design surface is built in AutoCADD by our Engineering Department from construction plans and is uploaded to the GCS900.

2)  Our Survey Department performs a Site-Calibration on Site.  A Site-Calibration converts the design surface coordinates to GPS coordinates which allows the D6R to know its location relative to the site.


3)  The Dozer Operator can then drive anywhere on site and know the precise cut or fill to finished grade.  The blade of the dozer is controlled by the GPS unit and will follow the design surface.

4)  The package also included a Rover unit which can be used On-Site separate from the Dozer to check grades, calculate volume of materials, and supply survey stakes.

So far it has seen action at both the Onekama Waste Water Treatment Facility and Wexford County Land Fill Sites.  It will soon be at the Village At Bayridge.
