RJS Construction Using High-Speed Dozer with GPS Machine Control

November 19, 2009

Superior’s RJS Industrial Services Group, a division of Reuben Johnson & Son, has become just the second construction company in the world to add a first-of-its-kind, high-speed dozer (HSD) to its operations. A contractor in the state of Virginia is the only other company besides RJS to have begun using the newly-developed John Deere 764 HSD, which finish grades and dozes up to twice as fast as traditional crawlers.

To further enhance productivity on the job site, RJS has equipped its new dozer with the world’s most advanced GPS machine-control system – the new Topcon 3D-MC2. It provides more than 100 blade-position checks per second, increasing speed and accuracy up to 200 percent over existing 3D systems. Together, the high-speed dozer and machine control system allow workers to do smooth and accurate grading on the first pass, rather than needing repeated passes and frequent adjustments, meaning one grader can now do the work of two in the same amount of time.

“RJS has always been committed to increasing efficiency to help our customers reduce expenses, and our new high-speed dozer and 3D GPS system have given us another modern way to do that,” said Dave Lemke, vice president of the RJS Industrial Services Group, adding that the dozer is now being used northeast of Grand Rapids, Minn., on a rail spur project that will serve the Essar Steel facility.

“Customers will be amazed at how nimble and precise this equipment is, at speeds reaching a previously-unheard-of 16 miles per hour. These enhancements help us save time, money, fuel and wear-and-tear on our equipment, while giving the customer a better result.”

Among the other features of the John Deere 764 HSD are an 11 foot wide blade and rubber tracks that allow it to traverse concrete and asphalt with no damage to roadways.
