CMI launches second Roto-Mill cold planer

CMI Roadbuilding has taken the wraps off a second Roto-Mill cold planer at the CONEXPO-CON/AGG show. The RM-6 joins the larger RM-7 launched last year, offering much of the performance of the bigger machine but with more compact dimensions. Powered by a Tier 4 Final Cummins QSX15 diesel engine, delivering 466kW, the RM-6 has a hydrostatic drive system with variable speed ground motors.

The Roto-Mill RM-6 provides a smaller footprint for contractors

8591 CMI Roadbuilding has taken the wraps off a second Roto-Mill cold planer at the CONEXPO-CON/AGG show. The RM-6 joins the larger RM-7 launched last year, offering much of the performance of the bigger machine but with more compact dimensions.

Powered by a Tier 4 Final Cummins QSX15 diesel engine, delivering 466kW, the RM-6 has a hydrostatic drive system with variable speed ground motors.

The RM-6 can be configured on three or four tracks with operating weights of 30.8 tonnes and 32.7 tonnes respectively. The machine comes with 914mm wide primary and secondary conveyors, there are operator panels for right- or left-hand control and the machine has a pivoting full-colour LCD display.

    Advances in transmission technology will help to optimise machine performance – writes Mike Woof. As construction machines have become more sophisticated, so have the transmission systems used in items of equipment. Advances in electronics and software in particular have allowed the development of integrated transmissions. These operate more efficiently and help optimise power delivery from an engine, boosting torque response and cutting fuel consumption and emissions at the same time. The smart electronics

    Driveline technology continues to develop rapidly, with many manufacturers at this year’s Conexpo exhibition showing Tier 4 Final emissions solutions, along with a host of fuel saving transmissions and hydraulic systems, all aiming to reduce operating costs for the customer. However, while there was certainly a hybrid presence at the show, things haven’t perhaps moved forward as fast as many had expected.
