Roadtec has equipped its RX-700 cold planer and its RX-900 milling machine with new engine options.
The new model of Roadtec’s RX-700 features the increased power of an 800 hp Tier 4 Final Caterpillar engine.
The new Tier 4 Final engine does not require diesel exhaust fluid as a component of the after-treatment system, which reduces operating costs typically required at this emission standard.
Thanks to the increase in power, the updated half-lane cold planer provides higher production and reliability.
“The increased horsepower delivers even more production. We give customers what they need: a reliable and efficient cold planer that helps them complete jobs on time and with success,” said Kyle Hammon, Roadtec’s product manager for mills, stabilizers and brooms.

The RX-700 cuts up to 35 cm deep with standard widths of 2, 2.2, 2.5 and 3.2 metres.
As well, the cutter housing includes angled moldboards, which prevent material from accumulating around the drum, resulting in less wear. Furthermore, track pads are bolted on, which makes changing pads fast, saving time and money.
To achieve a stronger and lighter frame, Roadtec used A656 Grade 80 steel when building the RX 700, which is twice as strong as common mild steel.
A 60-degree conveyor swing, which is greater than the traditional 40-degree swing, allows easy feeding of a truck in an adjacent lane or around a tight bend. A folding secondary conveyor is also available to aid in transport and loading.
Automated elevation controls
The Automated Control of Elevation (ACE) system automates machine elevation through a combination of grade and slope sensors. The operator and ground crew may easily make changes to the grade and slope parameters, on the job and in real time.
Roadtec RX-900
Roadtec’s RX-900e asphalt milling machine has been upgraded to a 1,055 hp Tier 4 Final Caterpillar engine. The new Tier 4 Final engine does not require diesel exhaust fluid as a component of the after-treatment system, reducing the operation costs typically required. The upgraded power and heavy-duty fabrication make the RX-900 ideal for half-lane and full-lane milling.
“The RX-900, like our entire Roadtec fleet, has been designed and refined with the goal of creating quality surfaces and successful outcomes for our customers,” Hammon said. “With a 1,050 hp engine, the RX-900 is the most productive cold planer available.”
Balanced power
The RX-900’s weight is well-balanced between the front and rear legs, maximizing traction and production. The cutter housing design includes 10 degree angled moldboards, which allows less material to accumulate around the drum resulting in less wear.
The RX 900 cuts up to 35 cm deep and cuts standard widths of 2.2 to 4.1 metres. It may also be outfitted to accommodate a variety of customized drum patterns.
The milling machine also incorporates the Automated Control of Elevation (ACE) System, which includes three graphic displays that provide continuous sensor monitoring and the ability to quickly transition between sensors.
As well, Roadtec outfitted the machine with Guardian Remote Telematics System, the industry’s only two-way communications system. Machine status, including electrical and hydraulic systems, is monitored in real-time via a wireless signal.
Machine settings can be modified remotely, avoiding costly downtime.
Adaptable conveyors
Finally, the RX-900 has 120-degree conveyor swing that allows for easy dispensing into a truck in an adjacent lane or around a tight bend, and an optional folding conveyor aids in transport and loading.
