Fitting to Tier 4 Final standards: New 8-tonners by Case

MUNICH/GERMANY, May 07, 2013 - Case Construction Equipment has showed new crawler excavators of the 8-tonne-class at  bauma 2013, which comply with latest emission standard. In addition new features provide more safety and comfort.

From 2014 on Tier 4 Final and Euro-IV emissions standards are binding for construction machineries. For halving NOx emissions in comparison to Tier 3 it will be not enough to build  more efficient diesel engines or fitting exhaust gas treatment systems  into the machines. Because space requirement within the engine bay increases due to components, vehicle manufacturers are forced to redesign as far as mainly little or medium construction machineries  are concerned.

The Tier 4 Final emissions standards have been met through the use of Cooled Exhaust Gas Recirculation (CEGR) combined with a Diesel Oxidation Catalyst (DOC) system. There is no requirement for these machines to have a Diesel Particulate Filter (DPF), which means there is no need for active filter regeneration that consumes fuel, and no need to replace the costly DPF.

The power to perform

The CX75C SR and CX80C develop 9% more hydraulic power than their predecessors. With 148 litres/min of pump flow compared to the previous 136 litres/min. Cycle times are reduced and digging force improved, up by 3%. In order to maximize uptime, the new machines feature a larger 120 litre fuel tank, that can easily be filled with the optional electric refuelling pump. Maintenance can be rapidly completed and is easier than ever. The radiators, filters, engine and hydraulic system can easily be accessed from ground level, providing safe and easy serviceability.

Safety and comfort for the operator

The short radius CX75 SR and the conventional CX80C have been developed with operator comfort and safety as design priority. The cab has been completely redesigned, meeting ROPS and FOPS Level II safety standards. Interior space has been increased, as the cab is 7% wider than the previous CX75 and CX80. A larger glazed area also improves visibility to the front of the machine. Rear visibility has been improved with the option of a rear view camera.

For specific applications that require additional safety, Case offers two different front screen guards and a certified lifting and handling kit to lift objects safely.

The new midis have the same full color monitor as larger excavators from the Case CX C Series. Both models are equipped with an efficient Automatic Air Conditioning system, which includes five adjustable air vents plus two defrost air vents, as standard.

Outstanding versatility

With a choice of three boom systems, (mono-boom, swing-boom and offset-boom), four auxiliary hydraulic control systems (either hand or foot controlled), three track options (rubber or steel shoes) and two dipper-stick lengths, the C Series mid-size excavators can handle a wide variety of applications.

Case midi excavators are the ideal choice for urban construction sites, thanks to their leading emissions performance and reduced dimensions. The CX75C SR has a 1,290mm tail swing radius and a 1,630 mm front swing radius, allowing the excavator to perform continuous swing and dump operations in less than a 3m working width.
