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.

Caterpillar is increasing its range of surface drilling products with the new MD5150C Track Drill, unveiled this week at Conexpo 2014. As the first of the company’s C Series drills, the MD5150C comes with a choice of three different rock drills and is said to deliver class-leading power and high airflow rates for the fast, efficient drilling of holes from 101.6mm to 152mm in diameter.
Sophisticated new paving technologies are coming to market that will help boost quality and performance. New paving technologies are being introduced to meet the differing demands of both North American and European customers. Although North American and European paving techniques do vary, there are also some control technologies being introduced that will help quality for both approaches.
Established players face increasing competition in the market for bulldozers and graders - Mike Woof reports The world’s largest manufacturer of construction equipment, Caterpillar is a company with a strong position worldwide and this has all grown from its track type tractor range. Caterpillar has long dominated the bulldozer market, as well as being involved in the grader segment since the inter-war period. The firm’s history ties it directly to the development of the crawler track with Ben Holt’s track
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.
