CASE Construction Equipment is introducing five new crawler excavators: the CX210D, the CX250D, the CX250D Long Reach (LR), the CX300D and the CX350D. According to the company, these new models are designed to provide significant operational gains, including cycle times up to 12 percent faster, improved responsiveness and multifunctional control, and up to 14 percent greater fuel efficiency. Breakout forces are increased by as much as 6 percent. Productivity testing during research and development showed that certain models in the D Series could fill more than 9,500 additional trucks per year based on cycle time increases alone.
Each model also offers more standard features than any previous CASE excavator, simplifying the buying process and making them extremely versatile and operator friendly. And all CASE D Series excavators provide peace of mind and lower total cost of ownership through CASE ProCare.
The new models include:
• CX210D: (160 horsepower; 48,973 pounds; bucket digging force: 31,923 – 34,621 foot pounds)
• CX250D: (177 horsepower; 56,909 pounds; bucket digging force: 36,419 – 39,566 foot pounds)
• CX250D LR: (177 horsepower; 63,523 pounds; bucket digging force: 17,310 foot pounds)
• CX300D: (207 horsepower; 67,271 pounds; bucket digging force: 39,342 – 42,781 foot pounds)
• CX350D: (268 horsepower; 82,483 pounds; bucket digging force: 51,639 – 56,157 foot pounds)
CASE D Series excavators meet Tier 4 Final emissions standards through an innovative combination of cooled exhaust gas recirculation (CEGR), 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. According to the company, these technologies, combined with the CASE Intelligent Hydraulic System, make the D Series the most powerful and efficient CASE excavators ever introduced.
Intelligent Speed, Power and Efficiency
Faster cycle times are the result of 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, D Series excavators re-use 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.
The D Series also provides the operator with three working modes – Speed Priority, Heavy and Automatic – that help the machine conserve energy and exert only as much power as needed to complete the job at hand, according to the company.
More Robust Design
The arm and boom of each new excavator have been built stronger for greater durability and to support the added power of the machine. The undercarriage is built with thicker steel and a new single-slope design that reduces dirt accumulation and eases cleaning.
Greater Feature Standardization
CASE D Series excavators now offer more standard features than any previous CASE 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 excavator features a fully adjustable operator station anchored by a standard heated air-ride seat and joystick controls that allow for smooth performance.
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.
Light it Up
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. A premium LED light package features the CASE Maximum View monitor, which combines feeds from three cameras to provide a comprehensive view to the rear and both sides of the machine.
CASE ProCare
CASE D Series excavators are covered under CASE ProCare – a suite of product assurances that includes a three-year Advanced CASE SiteWatch™ telematics subscription, a three-year/3,000-hour full-machine factory warranty, and a three-year/3,000-hour planned maintenance contract. ProCare allows business owners to invest in new equipment while helping to make owning and operating costs predictable for the first three years of lease or ownership.
