INTERMAT launch for updated D6N

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

D6N gets host of improvements
178 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 savings of up to 25%, said Cat.

The previous generation’s cast blade tower has been replaced by a fabricated and welded steel structure, enabling a ball-socket coupling – similar to that found on the D6T.
