EquipmentWorld.com | June 2015 49 C ase Construction Equip- ment recently demon- strated four of its's new D-Series crawler exca- vators, highlighting the push of the new series for boosted operator productivity. The lineup meets Tier 4 Final emissions standards. Five models make up the D series: the CX210D, CX250D, CX 250D LR, CX300D and CX350D, all of which of- fer up to 12 percent faster cycle times and up to a 14-percent improvement in fuel efficiency. The new lineup's faster cycle times come from an electronically controlled pump, a bigger control valve and multiple sensors; all combine with the company's Intelligent Hydraulic Sys- tem (IHS). The IHS is made up of four parts: Boom Economy Control (which cuts rpms via boom down and swing gravity); Auto Economy Control (cuts rpms during idle and shuts the engine down from a present idle time) Swing Relief Control (cuts hydraulic power when starting swing); and Spool Stroke Control (changes hydraulic pressure when digging). The three working modes of Speed Priority, Heavy, and Automatic draw just enough power needed for the task being performed. "The D series Series is a true game changer for Case and the industry with significant increases in speed, power, control, and fuel efficiency," says Philippe Bisson, Case brand marketing manager. The entire D series lineup, he added, is designed to increase produc- tivity and reduce operating costs. This ability to work faster translates into getting more work done, Bisson says. "During our field tests a lot of the operators came out of the machines and said, 'wow, that's fast'," he says. During research and development Case engineers created a simple measure of equipment efficiency: the number of trucks that can be filled in a year. "The CX300D was the undisputed champion (in the D Series lineup), and matched with the right truck, the CX300D can fill up to 9,500 more trucks in a year," Bisson says. "That's something an equip- ment operator can understand – filling more trucks at a faster rate, equals greater profitability. It also helps lower the total cost of ownership of the machine. And you're generating more profit in the same period of time without adding additional machines, labor, or often, expensive transportation." The D Series offers more standard features, Case says, than any of their previous excavators. These include Free Swing for craning, laying or lifting of offset loads; oil sample ports, a pattern selector for ISO or SAE controls, an adjustable operator station with a heated air-ride seat, Bluetooth radio and a rearview camera that feeds a 7-inch monitor. The series also is covered under Case ProCare. Optional features include an LED working light package with two lights in the front, two in the rear, and one on each side. product report | by Chris Hill | ChrisHill@randallreilly.com New model specs CX210D CX250D CX250D LR CX300D CX350D Power (horsepower) 160 177 177 207 268 Operating weight (pounds) 48,973 56,909 63,523 67,271 82,428 Bucket digging force (foot-pounds) 34,621 39,566 17,310 42,781 56,157 Case CE unveils 5 D-Series excavators with 12 percent faster cycle times The Case CX250D (left) and CX210D (right) in use at the company's Tomahawk facility.
