Full specification excavators

Building on the proven success of the C-Series crawler excavator range, CASE has developed the Short Radius CX145C SR and CX235C SR, taking performance and productivity to a new level. Featuring the CASE Intelligent Hydraulic System, the CX145C SR and CX235C SR deliver maximum economy and productivity from a compact yet powerful design, reducing operating costs of customers and boosting productivity.

Operator control

The new ROPS cab provides automotive levels of reduced noise and improved operator comfort. Visibility, space and seating have been improved and a new full-colour monitor delivers essential information and a camera feed for maximum safety and efficiency.

Short swing radius

The short swing radius allows excellent operation even in confined spaces. The new CX145C SR and CX235C SR are the perfect machines for road construction, bridges projects and in urban construction sites, any jobsite where space is limited. The new CASE SR machines are designed to increase productivity, giving the operator easier operation with performance, without the risk of machines damage, in other words superior safety on the job site.

Energy efficiency

The CASE Intelligent Hydraulic System (CIHS) incorporates a host of energy saving, performance enhancing functions, to boost efficiency and machine output. In combination with powerful, fuel-efficient Tier 4 Interim diesel engines, this leads to fuel savings of up to 17% for the CX235C SR and up to 9% for the CX145C SR. A simple operating mode dial delivers three working modes with Super Power set to provide maximum horsepower and hydraulic output. A Powerboost function provides an 8 second boost for maximum digging performance. Boom Economy Control increases energy efficiency during swing and boom lower operations, while Swing Relief Control further optimises energy use when slewing. Automatic Economy Control cuts energy use when the operating levers are in the neutral position and Spool Stroke Control delivers improved controllability in digging and levelling tasks.

The machines feature automatic engine idling and automatic engine shut down, to further cut unnecessary fuel use when not working. Pump Torque Variable Control provides perfect control of the engine and hydraulic system, further boosting economy. Despite this focus on reduced consumption, the SR excavators boast a 5% improvement in cycle times with a 6% improvement in lifting performance.

Robust quality

The short radius machines continue a CASE tradition of robust design and high quality build. By bringing together the highest quality components and materials, in a machine that has been designed to work productively, CASE has further improved reliability and durability, reducing ownership costs and cutting downtime for the customer.

Safety and Maintenance

Open Close

Simplified maintenance

All filters are grouped together for easy access, reducing service time. In addition remote greasing points and standard EMS bushings cut greasing intervals to every 1,000 hours. A synthetic fi lter extends hydraulic oil service intervals to 5,000 hours while engine oil change intervals are set at a competitive 500 working hours. Side-by-side coolers and radiators are easily accessed for cleaning and maintenance, with a removable mesh filter cutting downtime and boosting productivity for the customer. A redesigned upper structure provides access to all service points from ground level, with large side opening access doors. A standard 100 litre/min refuelling pump with automatic stop function and larger tank keeps downtime to a minimum, ensuring maximum productivity for up to two working days.

Operator comfort and safety

CASE SR excavators take operator comfort to the next level, with a new 7% larger ROPS and FOPS Level 2 cab that delivers an almost automotive noise level. An improved air conditioning system (28% more airfl ow and 20% increase in performance), multi-adjustable suspension seating, increased foot space, cup holder and storage compartments deliver the most productive working environment possible. Visibility is improved and the CASE machines feature a new full-colour Multifunction Display. This extra large LED screen provides important machine information in a clear, easy to use menus format. Rear and side view cameras can be viewed using a split-screen facility, while vital machine data remains clearly visible. An ECO gauge provides a constant real-time recording of fuel consumption, allowing the operator to reduce power and conserve fuel when possible, improving efficiency and productivity. The monitor also provides access to on-board diagnostics, reducing downtime for service and maintenance.
