New dozer series among Case's Bauma launches

Operating weights range from 13 tonnes to 20 tonnes and each boasts reduced exhaust and noise emissions.

Hydrostatic transmissions is used to deliver drawbar pull of 213.5kN for the 1150M, 311kN for the 1650M and 374kN for the 2050M.

Selective catalytic reduction (SCR) technology is used to meet Tier IV Interim engine regulations.

Also to be launched at Bauma are Case’s first Tier 4 Final midi excavators. These develop 9% more hydraulic power than predecessor models, Case says, thanks to high flow hydraulic pumps. Cycle times are reduced and digging forces increased by up to 3%, the manufacturer says. Cabs are also 7% wider but have the same monitor and operator interface as the larger CX C crawler excavators.

The short radius CX75 SR and the conventional CX80C (pictured below) use cooled exhaust gas recirculation (CEGR), and a diesel oxidation catalyst (DOC) to meet the exhaust standards. There is no requirement for a diesel particulate filter or for regeneration.

The 621F wheeled loader (below) will also make its first appearance at a European show in April. The 12.2-tonne machine is powered by a second generation common-rail Tier 4 Interim engine, using SCR technology. 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, Case says.

Bauma 2013 takes place in Munich, Germany from 15-21 April.
