In a move that has taken the construction equipment industry by surprise, Caterpillar unveiled at Conexpo its first bulldozer powered by an AC electric drive. Cat said that the D7E offers "significant productivity increases and reduced owning and operating costs". Backed-up by over 100 patents, the mid-range machine will be introduced in selected markets during 2009. "From an environmental sustainability perspective, the D7E uses substantially less fuel per hour - dramatically reducing the amount of carbon

Komatsu has announced that it has added a hybrid powered excavator to its product line-up, which the company claims offers significant reductions in fuel consumption compared to conventional diesel powered machines. The PC200-8 machine was formerly launched in June for the Japanese market and a spokesman for the company said that it is planned to be launched in other markets later but no date has yet been set. The machine is powered by the Komatsu Hybrid System which uses a newly developed electric motor to

Marangoni has introduced new products to its range of large-sized tyres. The new products from the Italian company, available in sizes 27.00x49, 31/80x49 and 31/90x49, have been developed with the MRLS Recaflex and MDT Recaflex profiles, and have a deeper tread pattern than the previous models, increased from 70 to 75 mm. This feature, combined with a larger footprint and a low hysteresis compound, is said to guarantee longer tread life, with maximum hourly performance and without negatively affecting casin

Slurries with specific gravity of 1.15kg/dm³ present a serious challenge for many pumps, but Toyo claims that its latest new models are ideally suited to such conditions. The new GR pumps benefit from an integrated agitator along with technical specifications adapted to the density of medium slurries, which Toyo said offers an effective solution for a competitive price. The newest GR30 and GR30B also benefit from a self cooling system and can operate partially immersed but also at depths up to 30m, in liqui

As the construction equipment industry heads to Paris for Intermat 2009, ABE reports on the latest new quarry machines that will be launched at the show Visitors will get a chance to view Komatsu's HM250 in the iron Prospects of economic stimulus packages from governments around Europe mean that while general construction is in a slowdown, there are plans for major infrastructure investment. With this will come the demand for aggregates and the need for the latest technology in order to match this demand wi

Michelin launched the first radial earthmover tyre 50 years ago. Claire Symes takes a look at the development The shortage of earthmover tyres has been regularly reported in the news recently, but 50 years ago such tyres were hitting the headlines for very different reasons. It was in 1959 that Michelin introduced the XR tyre - the first radial tyres for earthmoving equipment - and took tyres for construction equipment into a new era. Michelin's XR concept was tried and tested as it was based on the radial

Quarry operators looking to buy new equipment this year may well come away from a dealer or an exhibition stand in some confusion. The reason for this understandable bafflement is exhaust emissions, or possibly the lack of them.
Many will be familiar with the European Union’s Stage IIIB and US Tier 4 Interim emissions standards that affect most off-highway equipment, and manufacturers have been falling over each other to launch new kit equipped with these engines for some time now. But things are not as si
