CASE CX350D excavator

CASE Construction Equipment introduces five new crawler excavators: the CX210D (160 horsepower; 48,973 pounds; bucket digging force: 31,923 – 34,621 foot pounds), the CX250D (177 horsepower; 56,909 pounds; bucket digging force: 36,419 – 39,566 foot pounds), the CX250D Long Reach (LR) (177 horsepower; 63,523 pounds; bucket digging force: 17,310 foot pounds), the CX300D (207 horsepower; 67,271 pounds; bucket digging force: 39,342 – 42,781 foot pounds)  and the CX350D 268 horsepower; 82,483 pounds; bucket digging force: 51,639 – 56,157 foot pounds). These new models provide cycle times up to 12 per cent faster, improved responsiveness and multifunctional control, and greater fuel efficiency.

CASE D Series excavators meet Tier 4 Final emissions standards through a combination of cooled exhaust gas recirculation (CEGR), selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) technologies. There is no diesel particulate filter (DPF), no DPF regeneration or associated lifetime service costs. Faster cycle times are the result of an 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.

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. 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.

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. These excavators also feature a pressurized and iso-mounted cab that keeps noise and vibration down. A standard Bluetooth radio gives operators hands-free functionality. 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.
