CASE Expands D Series with CX245D SR Minimum-Swing Excavator
Greater fuel efficiency, precision maneuverability and increased bucket digging force and lift capacity.
CASE Construction Equipment has introduced the all-new CX245D SR minimum-swing radius excavator to its D Series lineup. Designed to provide increased digging and lifting power in confined work areas, the CX245D SR features a compact counterweight and modified boom placement that minimizes the machine’s footprint, resulting in a highly productive and maneuverable excavator that’s ideal for restricted conditions, such as road and bridge work, residential projects and urban construction.
With an operating weight of 60,400 pounds and a 160 HP Tier 4 Final engine, the CX245D SR offers increased bucket digging forces (up to 34,600 pounds) and lift capacity (up to 22,950 pounds) compared to the previous model. Each D Series model is built to provide significant operational gains, including decreased cycle times, improved responsiveness and multifunctional controls, and greater fuel efficiency. An electronically controlled hydraulic pump and larger control and solenoid valves increase lifting capacities and improve responsiveness.
The CASE CX245D SR excavator meets Tier 4 Final emissions standards through an innovative combination of selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies, which helps maximize uptime and performance – all with minimal maintenance. There is no diesel particulate filter (DPF), no DPF regeneration or associated lifetime service costs. These technologies, combined with the CASE Intelligent Hydraulic System, make the CX245D SR the most powerful and efficient minimum swing radius excavator CASE has ever introduced.
Intelligent Speed, Power and Efficiency
Faster cycle times are achieved through a new electronically controlled pump, a larger control valve and multiple sensors. These features combine with the CASE Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency.
The four systems that make up the CASE Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; Auto Economy Control (AEC), which lowers RPMs during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which reduces hydraulic power at the swing start; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs.
Using improvements to the Spool Stroke Control system, the CX245D SR excavator re-uses hydraulic fluid whenever possible to automatically increase cycle times and efficiency. The operator experiences a more productive machine without losing the precision of the machine’s controls.
CASE D Series excavators now offer more standard features than any previous CASE crawler excavator. This includes Free Swing for improved craning, laying or lifting of offset loads; oil sample ports for quick sampling of engine and hydraulic oils; and an easy pattern selector for the operator’s preference of ISO or SAE controls. Each D Series machine features a fully adjustable operator station anchored by a standard heated air-ride seat and joystick controls that allow for smooth performance.
The CX245D SR also features best-in-class cab space, excellent visibility, and a pressurized and iso-mounted cab that keeps noise and vibration down. A standard Bluetooth radio gives operators hands-free functionality that further improves the operator experience. A standard rearview camera feeds a 7-inch widescreen monitor that also provides operators with real-time access to important performance parameters, including fuel consumption, operating hours and machine information. Each machine is available with a new (optional) LED working light package that provides illumination similar to sunlight – and more than three-times brighter than halogen – allowing contractors to work around the clock. The LED package includes six LED lights (two front, two rear and one on each side) and a side-view camera.
