On a recent project at O’Hare International Airport, K-Five Construction Corporation machine operators had a hump on a shoulder they were milling; the ACE® System on the Roadtec RX-700e cold planer allowed them to easily switch from 2 in (5.08 cm) grading to two percent slope and then back to the 2 in (5.08 cm) grade without hesitation and in one pass.
With the ACE Grade and Slope Control System on three of our milling machines, we can now mill with greater precision.
In the paving and milling market, innovation is at risk for being an overused word. Technology has been changing the way machines perform—improving productivity. Advances and refinements have made brand new machines perform better, experience less frequent break downs, and last longer than models that are even just a few years older.
The Revolutionized Tool
The term innovation can be used to appropriately describe the ACE® Grade and Slope Control System thanks to all the advances that have been made in automation, machine control, and the software that runs it. The Automated Control of Elevation or ACE System from Roadtec is designed to automate the elevation of the milling machine using a network of grade and slope sensors combined with one central microcontroller. This technology can be added to older machines to upgrade and improve their performance.
“We’re running the ACE Grade and Slope Control System on three of our mills—and can now mill with greater precision,” stated Bobby Hernandez, milling foreman with K-Five Construction Corporation, based in Lemont, Illinois, “On a recent project at O’Hare International Airport, we had a hump on a shoulder we were milling and the system on our Roadtec RX-700e cold planer allowed us to easily switch from 2 in (5.08 cm) grading to two percent slope and then back to the 2 in (5.08 cm) grade without hesitation and in one pass. Plus, we were within ¾ in (1.91 cm) accuracy when we finished.”
The ACE System is available on all half-lane and full-lane milling machines. It includes three graphic displays that are designed to provide enhanced operation, sensor availability, continuous sensor monitoring, and the ability to quickly transition between sensors. The system is designed to incorporate the additional hardware, sensors, and other components needed for single or dual averaging skis.
Advanced programming and user-friendly displays makes it possible for the machine operator to auto-calibrate the hydraulic parameters, reducing the time and effort spent troubleshooting.
“The ACE control system can also be directly connected to the Roadtec Guardian™ Telematics System, which is a custom remote diagnostic system for our machines that can address a problem remotely and correct it to maintain the contractor’s productivity,” stated Max Peters, Guardian account manager with Roadtec. “The ACE System adds additional data which Guardian can use to help a contractor remain productive.”BACK TO ISSUE
