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.

Bell will start production later this year of its motor graders for Stage 3 markets after years of research, development and having prototypes on site.
Jeremiah Mokhomo, Bell Equipment product manager, explained that the Tier 3 range consists of three base models, each available in either a 4WD or 6WD configuration. The G140 is well suited to all maintenance and light to medium construction tasks. The G160, with its increased power and performance, is designed to handle heavy construction applications, while the G200 is designed for bulk earthworks and the mining industry.
Wacker Neuson is now offering a heavy-duty wheeled loader with the introduction of its WL95 model. The new 10tonne class machine is the largest wheeled loader offered by Wacker Neuson but retains the firm’s compact design. It features the latest ecospeedPRO transmission, with customers offered a choice of two engine versions that meet the latest emission standards.
The machine is designed for materials handling applications with large construction contractors and recycling companies. Wacker Neuson will now
Innovative developments are pushing forward concrete road construction techniques. The concrete road sector looks to benefit from some key innovations and developments now coming to market or being employed in different territories. Irregular weather and environmental conditions can alter the rate at which concrete cures, with a risk of plastic shrinkage cracks that can compromise the integrity of a pavement. Contractors cannot control the environmental conditions of a paving project and when weather patter
LeeBoy is seeing strong sales for its road machines at the moment, particularly in the US. And the firm’s early investment in fitting Tier 4 Final compliant engines has played a significant role
Christopher Barnard is CEO of LeeBoy and commented, “The US has been strong. Demand is there and the infrastructure spending is there. It’s a good market. In our segment for commercial paving we’re doing very well.” The paver range is selling well and the firm’s 8520 model is a particularly strong seller. Barnard
