Caterpillar has given its D6N fine grading and muck-shifting dozer an EU Stage IIIb emissions-compliant engine for 2012.
The 129kW C6.6 Acert engine now gets a DOC and DPF with passive regeneration, helping the machine to a 2% productivity boost primarily from sharper throttle response.
There is also a selectable economy mode – linked to 2nd gear – that automatically shifts the dozer into 3rd gear when reversing, and simultaneously reduces engine revs from 2000 to 1700rpm. This system can give fuel saving
Modern satellite technology is making life easier for everyone on the construction site and in the office. Most major equipment manufacturers are now integrating GPS machine control systems into the design of excavators, bulldozers, pavers, and motor graders. For stake-less work it is a major component for automatic grading, surveying, and excavating systems, with contractors and construction companies using GPS machine control systems to improve operations.
Rob Oliver is the longstanding CEO of the Construction Equipment Association (CEA), the UK trade association for the UK construction equipment industry. Guy Woodford recently caught up with him to discuss the industry’s health and the key issues facing the CEA and its members in 2021 and beyond.
Hydraulic breaker specialist Indeco has developed new fuel-saving technology for its entire range of breakers. Compared to other breakers of the same size and capacity, Indeco’s can now deliver fuel savings of around 20%.
“If you consider quarrying, by far the biggest cost is the fuel that the excavator consumes. If you can reduce the fuel used, you reduce your overall cost of production significantly,” said Indeco’s marketing director Michele Vitulano. “Reducing fuel consumption is also important for ro
