INTERMAT launch for updated D6N
D6N gets host of improvements
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The previous generation’s cast blade tower has been replaced by a fabricated and welded steel structure, enabling a ball-socket coupling – similar to that found on the D6T.
