CASE continues to expand its compact crawler excavator range. The latest additions to a line-up that includes more than 20 individual models, are the E- Series midi models that cover the 8-10 tonne operating weight market.
Those customers looking for a zero-tail swing design with a fixed mono boom, similar to a full-size crawler model, can opt for the CX85E, with an operating weight of 8,830kg. For operators that prefer a boom swing solution like a mini excavator, for improved access on constricted sites, the CX90E weighs in at 9,210kg. The ultimate flexibility, with a longer horizontal reach and higher dump height, comes with the CX100E. This 10,080kg model offers a zero-tail swing design, with a two-piece articulating boom (TAB) and boom swing.
For additional stability and lifting capacity, the CX85E and CX90E can be ordered with an additional 440kg counterweight, which is standard on the CX100E. Mounted internally, the additional weight does not impact the zero-tail swing overhang, maintaining the compact dimensions of these 8-10 tonne class machines. All three of the machines can also be equipped with an external 900kg additional counterweight if required.
All three models are powered by a 53.7kW (73hp) diesel engine. With a variable displacement hydraulic pump, there are three operating modes available, including economy for maximum fuel efficiency. Along with the three factory presets -economy, standard and power – it is possible for the operator to program an Individual setting, adjusting the speed of each hydraulic function to suit their preference.
The machines benefit from up to three auxiliary circuits, that can be set to match the flow requirements of different attachments, to provide maximum operating efficiency and performance. Electro-proportional roller switches in the joysticks provide fingertip control of auxiliary functions.
CASE has also introduced a joystick travel mode, allowing the operator to control all tracking functions from the lefthand joystick. This is particularly useful when using the dozer blade for backfilling applications and travel. These three models are equipped with dual-speed transmission, with automatic shift-down when required, delivering optimum traction in all situations.
The premium cab environment offers three types of seating, including mechanical or pneumatic suspension and seat heating. Ergonomically-designed joystick levers with intuitive push buttons and electro-proportional roller controls maximise productivity and reduce fatigue for the operator, while the multi-function computer display provides access to control menus, diagnostics and hydraulic adjustment screens.
Air conditioning components have been located within the rear roof spoiler, which rotates within the counterweight dimensions. This location maximises visibility from the cab, while rear view mirrors and cameras offer the operator an all-encompassing view around the excavator. LED lighting completes the visibility package, ensuring maximum vision in all light conditions and weather.
