Roadtec’s RX600eLR offers versatility for milling
1252 Roadtec is now developing its RX600eLR milling machine as a more versatile unit for the 2m class. The machine has been unveiled in prototype form, with full testing set to commence shortly. A key development for the RX600eLR is that the drum is driven by two hydrostatic motors, with one mounted on each side.

International marketing director Eric Baker said, “It can cut flush on both sides. It’s important for every market because you can’t go against traffic.” He explained that in most markets, road authorities do not allow construction machines to operate against the flow of traffic and added, “In right hand drive countries they’re fighting with that belt drive sticking out.”

The hydrostatic drives do provide benefits for the user. Baker said, “There are some advantages as you can adjust the speed infinitely and if you hit any obstructions, the hydrostatics can respond very quickly.”

He went on, “We built left hand flush cut machines before.” However this new design is more versatile and offers a much wider range of capabilities. With a standard machine it is possible to change the speed of the cutter drum by adjusting engine rpm but that approach has its limitations as it means there is a restriction on the power available. It is possible to change pulleys to adjust cutter drum speed, but this takes time and only allows a few speed options. Being able to adjust the speed infinitely allows the user to match the unit to the operating conditions. Power comes from a 196 Cummins diesel rated at 503kW and which meets Tier 4 Final/Stage IV emissions requirements.

This concept is more versatile and allows flush cutting alongside kerbs and New Jersey type barriers, no matter which side of the road vehicles drive on. And Baker continued, “We didn’t see the need for a slide on the cutter drum as we built the machine narrow enough and we can just crabsteer it around manholes. The drum housing is out past the outside of the machine and the tracks are set in a bit.”

The machine weighs around 30tonnes and can also be equipped with standard milling features including grade control and dust extraction.

    3D machine controls can optimise milling efficiency, Mike Woof reports. More efficient milling and recycling operations can be carried out by using the latest 3D control systems on the market. At the last Trimble Dimensions event in Las Vegas, the advantages of 3D controls for milling operations proved a key topic. The use of 3D control systems can offer huge advantages in milling operations. This technology helps increase productivity as the milling machine will only remove what is required, which also hel

    Minnich Manufacturing, a maker of concrete dowel pin drills, concrete paving vibrators and vibrator monitoring systems, has developed a concrete barrier wall drill. The tool drills vertical holes for the pins used to secure temporary concrete traffic barriers. Minnich, based in Mansfield, Ohio, said the air-driven and self-propelled drill straddles and rides along the top of the temporary wall. A tethered controller enables the operator to simultaneously drill three accurate, consistent pin holes — through
