CASE Construction Equipment has introduced two new crawler excavators to its D Series lineup: the CX490D and CX500D. These new models are designed for heavy excavation work and replace the company’s previous 47-metric ton excavator the CX470C. Each model is built to provide significant operational gains, including cycle times up to 10 percent faster, improved responsiveness and multifunctional controls, and greater fuel efficiency.

D Series models offer more standard features than previous CASE excavators, simplifying the buying process and making them extremely versatile and operator friendly. All CASE D Series excavators provide peace of mind and lower total cost of ownership through CASE ProCare.

The CX500D—the largest Tier 4 Final excavator in the D Series—is a dedicated model for mass excavation that provides outstanding breakout forces and performance. With a special heavy-duty attachment coupler, larger bucket cylinders and optimized kinematics, the CX500D works with larger buckets than the CX490D, providing industry leading speed, productivity and efficiency. Both models are available with an optional hydraulic counterweight removal device for improved on-site safety and efficiency during transportation.

The CASE CX490D and CX500D excavators meet 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 D Series the most powerful and efficient CASE excavators ever introduced.

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.

These excavators also feature 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.
