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.

Ensuring efficient cone crusher operation can deliver major economies of scale for quarrying facilities There are a number of ways in which cone crusher throughput can be optimised. One of the key issues is in keeping the system choke fed during operation, as this maximises the effectiveness of rock-on-rock crushing, extends the wear life of manganese components and ensures a quality product shape. A lack of feed causes inconstant loading, which affects the long-term life of internal components.
Komatsu Europe is now offering the versatile and compact PW118MR‐11 wheeled excavator. This midi excavator has a short tailswing and is powered by a low emission Stage IV engine, offering a 6% fuel saving over earlier models. The machine is said to be rugged and stable, with a class‐leading performance for its compact size. The machine is said to combine power, precise control and compact dimensions, suiting it to use for excavating tasks in narrow alleys or on road‐construction sites for example.

A series of innovations in machine control or automation technologies are helping transform the construction industry - Mike Woof writes Equipment manufacturer have made huge advances in machine performance, delivering new models that offer increased capabilities and productivity, while using less fuel. Reliability and uptime too have been improved, with the development of equipment that can forestall unplanned downtime by telling the user when it will require service attention. Meanwhile new engines delive
Rockmore International is adding its new ROK 550T drill to its T Series DTH hammer line. The T Series DTH hammers are TUBELESS and use drill bits featuring industry standard shank connections without the embedded plastic blow tube/foot valve. The firm’s first T Series DTH model was the ROK 600T, a 152mm class model that uses a tubeless QL6/QL60 bit shank. The company then expanded the T Series with the ROK 60T-360T hammers that use the IR 360 bit shank without the blow tube/foot valve. And Rockmore is now
