Tier 4 Final launches from Case

18 March 2013

Case’s stand will include the Tier 4 Final-compliant CX80C excavator

Machines with engines that comply with the up-coming US Tier 4 Final/EU Stage IV diesel emissions laws will be a key trend in terms of launches at this year’s show, and Case is no exception.

The manufacturer’s stand will feature two Tier 4 Final-compliant midi excavators – the short radius CX75 SR and the conventional CX80C machine. These 8 and 9 tonne class excavators are said to produce 9% more hydraulic power than previous models.

The Tier 4 Final emissions standards have been met through the use of cooled exhaust gas recirculation combined with a diesel oxidation catalyst system. Case said there was no requirement for these machines to have a diesel particulate filter, which means there is no need for active filter regeneration that consumes fuel, and no need to replace a DPF.

Case will also introduce a new three-model range of M Series dozers at the show. This expanded line-up includes dozers with operating weights of 13 to 20 tonnes that use hydrostatic transmissions to deliver a drawbar pull of 213.5kN for the 1150M, 311kN for the 1650M and 374kN for the 2050M. The dozers are fitted with Tier 4 Interim-compliant engines.

Three new wheeled excavators from Case will also be on display at Bauma. The WX148, WX168 and the show debut of the 621F – a 12.2 tonne machine powered by a Tier 4 Interim-compliant engine.

And the manufacturer will also showcase its new 621F wheeled loader – a 12.2 tonne machine that will make its first appearance at a European show at Bauma. Powered by a Tier 4 Interim engine, the machine uses selective catalytic reduction (SCR) technology to comply with current emissions laws.

As with larger F Series models, the 621F has a cooling pack directly behind the operator’s cab, moving the engine to the rear of the machine to reduce counterweight. Cooling radiators form a cube behind the cab around the cooling fan, ensuring that clean air is blown through each radiator. This increased cooling efficiency results in longer coolant life and reduced ownership costs for the customer, said Case.
