CNH Construction marketing director Jean-Patrick Yekpe has highlighted the money-saving potential of Case Construction Equipment’s new midi-excavators, unveiled at bauma 2013. The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system. “When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of thi
The Tier 4 Final requirements of the CX75C SR and CX80C have been met, says Yekpe, through the use of cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst system.
“When the soot is coming out of the engine as smoke and touches the platinum inside the engine you get an oxidation, and as a consequence of this chemical reaction you do not have any more soot coming out,” explained Yekpe.
“The benefit for the customer of this technology is that you do not need a diesel particulate filter. The main inconvenience of this (DPF) is that it is costly,” he said.
Meanwhile Phil Marshall, UK business manager for Case Construction Equipment (Case CE), said the new midi-excavators represented a step back into an important market for the brand. “This is particularly so within my home country, the UK,” he said.
The CX75C SR and CX80C are said by Case to generate 9% more hydraulic power than their predecessors, and 148litres/min of pump flow compared to the previous 136litres/min. Cycle times are said to be reduced and digging force improved by up to 3% with Case CE’s new midi-excavators.
To increase uptime, the bauma 2013-launched machines feature a larger 120litre fuel tank, said to be easily fillable with the optional electric refuelling pump. Efficient maintenance is another advantage of the CX75C SR and the CX80C, stressed Case CE.
Both new midi-excavators have a choice of mono-boom, swing-boom and offset-boom, four auxiliary hydraulic control systems (hand or foot controlled), three track options (rubber or steel shoes) and two dipper-stick lengths.
