CASE launches heavy-weight CX490D and CX500D quarry

CASE Construction Equipment is launching the CX490D and CX500D as part of the manufacturer’s new generation D-Series crawler excavator offering in the quarrying sector. Like their earthmoving cousins, the CX160D and CX180D and the utility sector CX130D, the larger models feature CASE’s fuel-efficient Tier 4 Final (Euro IV) maintenance-free technology with no DPF. The CX490D adds around 1.5tonnes to its predecessor in the C Series, bringing its weight very close to 50tonnes. At the top of the range

176 CASE Construction Equipment is launching the CX490D and CX500D as part of the manufacturer’s new generation D-Series crawler excavator offering in the quarrying sector.

Like their earthmoving cousins, the CX160D and CX180D and the utility sector CX130D, the larger models feature CASE’s fuel-efficient Tier 4 Final (Euro IV) maintenance-free technology with no DPF.

The CX490D adds around 1.5tonnes to its predecessor in the C Series, bringing its weight very close to 50tonnes.

At the top of the range, the CX500D in mass excavation version has an operating weight above 50tonnes. These two heavy duty models, which replace the previous generation’s CX470C and CX470C ME, have been renamed to reflect their increased weight.

The new models have an after-treatment Selective Catalytic Reduction (SCR) system and Diesel Oxidation Catalyst (DOC). Exhaust gases are treated exclusively through chemical reactions in the SCR and DOC. No particles are trapped in the system, so that no Diesel Particulate Filter (DPF) is required.

This is a very simple and effective solution to dramatically reduce polluting emissions and, as it is an after-treatment system, the engine runs at optimum efficiency to deliver more power with less fuel. As a result, customers enjoy significantly lower fuel cost. The system is also very economical in its use of AdBlue, which is just 3% of fuel consumption. In addition, because there is no DPF regeneration or DPF replacement, maintenance and operating costs are remarkably low.
 
Three working modes – Speed Priority, Heavy and Automatic – help the machines conserve energy and exert only as much power as needed to complete the job at hand.

The new models also feature CASE’s energy saving systems, which include Pump Torque Control, Auto-idle and Idle Shutdown functions, Spool Stroke Control, Boom Economy Control and Swing Relief Control. These take advantage of every fuel saving opportunity, further reducing operating costs and contributing to a longer life for the machine.
