CRAWLER EXCAVATORS

INCREASED PRODUCTIVITY

All CASE C Series excavators have improved performance and productivity as part of the CASE Intelligent Hydraulic System. The most obvious changes are the new monitors in the C Series machines that provide operators with the chance to pre-program auxiliary hydraulic flow and pressure settings with the option for up to 10 attachments, providing rapid changeover and increased productivity. They also use the familiar working mode control from the B Series machines, making it easy for an operator to become familiar with the new models. The H and SP Modes even provide a 5% boost when required to maximise digging ability.

Changes to the engineering design have improved the C series too with all models benefiting from lift capacity increase and cut cycle times, and that’s only the start. Gently increasing the operating weights has given stability and consistency to the digging and loading of greater loads, enabling higher production volume. Bucket and boom down regeneration systems feed hydraulic oil back to the supply side of the pump, further reducing the power requirement from the engine.

FIRST CLASS OPERATOR ENVIRONMENT

The C Series cab is 7% larger than the previous models and uses a smaller top beam with no overlap in the front windows, offering improved, all-round visibility. New mirrors and a standard rear view camera improve visibility too, with an optional side camera, and an improved 7” LED monitor inside the cab, providing the operator with a safe and secure working environment.

Noise levels are reduced to almost automotive standards, around 70dB(A), and a suspension seat and fully adjustable levers are standard for operator comfort. Travel pedals require less effort and reduce operator fatigue too. The ROPS/FOPS level 2 certified cab sits on new suspension mounts to reduce vibration for the operator and contributes to the lower internal noise levels. The cab has a powerful air conditioning system with 25% more airflow and an 8% increase in overall performance.

FIRST CLASS SERVICEABILITY

All filters and regular fill points are grouped for easy access, with engine oil change intervals set at 500 hours. A synthetic filter is used for the hydraulic oil, providing 5,000 hour intervals, and all pins and bushes (except the bucket pin) use the CASE Extended Maintenance System bushings, allowing greasing intervals of up to 1,000 hours. The radiator and cooler cores are mounted side by side, to allow easy access for cleaning and more efficient cooling. The Japanese-built CASE excavators boast an enviable reputation for reliability and durability, which looks set to continue with the new C Series of CX class crawler excavators.
