New Holland unveil new C-Series excavators

Company unveils E265C and E305C crawler excavator models at Samoter exhibition 

AT Samoter 2011 New Holland launched the first two models in their new C-Series range of crawler excavators – the E265C and E305C. With operating weights ranging from 27 to 31 tonnes, the machines have been specially designed to optimize performance and productivity thanks to a number of technological advances.

These include: Tier 4 Interim engines; a higher efficiency hydraulic system that is said to increase productivity by up to 10%; a new EVO cab with ROPS/FOPS protection; and a new heavy-duty design with reinforced undercarriage. 
 
The Tier 4 Interim-compliant engines on the New Holland equipment feature selective catalytic reduction (SCR) technology developed by FPT Industrial. The solution is based on an after-treatment system that breaks down the NOx into nitrogen and water through a chemical reaction with a diesel exhaust fluid (DEF), which is marketed under the AdBlue registered name in Europe.

The combustion process is optimized to reduce particulate matter (PM) so that no particulate filter is required. The SCR system is fully integrated into the design of the excavator – the catalyst in the counterweight and the DEF tank in the new toolbox.

According to New Holland, the average rate of consumption of AdBlue is 5% of fuel, so the tank only needs to be refilled every 4th or 5th fuel tank refill, which, on average, is every eight to 10 days.

The redesigned hydraulic system on the C-Series models – encompassing the main pumps, spool, solenoid and return valves – has significantly increased the machines’ controllability and hydraulic efficiency. The new system is said to provide 100% pump utilization in all applications and minimizes friction losses and pressure drops, resulting in higher productivity.

New Holland also claim that the new ECO operating mode further enhances the excavators’ fuel economy, reducing consumption by 10% compared with the B-Series.  

The new EVO cab features a host of improvements to ergonomics and control layout, with a new colour monitor and more responsive joystick. The new dampers reduce vibrations by 30% when travelling and by up to 50% when digging. The narrow-shaped pillars of the ROPS/FOPS reinforced structure, together with a new right-side window and rear camera, further improves the all-round visibility for the operator.    

The heavy-duty E265C and E305C machines are available in a variety of configurations, with guards and protection suitable for quarry and demolition applications.
