Turbocharger package cuts emissions and boosts fuel efficiency
Cummins’ latest turbocharger innovation has been extended to the 500-series, with an electronically wastegated turbocharger that delivers efficiency gains of up to 8% as a result of changes to the exhaust turbine. By more closely matching turbine wheels to the compressor, greater fuel efficiency is achieveable, said the firm. The 500-series turbocharger is also said to offer improved resistance to oil leakage by 200% over the current industry standard.

Sophisticated dual layer paving technologies currently on the market are said to offer major advantages to road builders. Roads built using twin layer, hot on hot paving techniques can last considerably longer than those constructed using conventional methods.
Contractors and clients also stand to gain from savings on materials costs, through the elimination of the need for emulsion spraying between binder and wearing courses and with the use of thin layer wearing course designs. At present two paver man
Dana and Mecalac have collaborated to develop an innovative wheeled excavator featuring an all-electric drivetrain. The firms have developed the special e-Drivetrain system for the new Mecalac e12 electric compact wheeled excavator. This machine recently won the Energy Transition Award as part of the 2018 Intermat Innovation Awards.
Based on the proven Mecalac 12MTX model, this version is the world’s first all-electric compact wheeled excavator. The machine features Spicer 112 axles and a Spicer 367 shift-
Innovative materials testing technology will allow the road sector to boost pavement quality, Mike Woof and Patrick Smith report. With billions being spent on highway construction worldwide, governments are looking to make sure their investments last as long as possible.
Customers can face the choice of buying used or new equipment – Dan Gilkes writes. The decision to buy either new or used equipment is almost as old as the construction plant market itself. However some of the reasons for choosing between the two might well be changing, to meet new demands from customers across the world and to cope with a changing supply base. Ever more stringent emissions legislation in Europe, the US and Japan, rapidly developing emerging markets that want the productivity of the latest
