Case Construction Equipment introduced the 153,400-pound CX700, which fills a vacant weight slot between its CX460 and CX800 models. The CX700, powered by a Tier 3-certified Isuzu diesel rated at 425 net horsepower, digs to 31 feet 11 inches and reaches to 46 feet 11 inches at ground line. For improved durability, Case designed the CX700 using the frame from the heavier CX800.

The new model provides a familiar set of features for long-time customers, according to Case, including four work modes, auto power boost and a climate-controlled, iso-mounted cab; it also includes several new items — among them, a switch that allows the operator to give priority to either the boom or swing functions. By flipping the boom priority switch, the operator channels flow and speed to the boom, which can be helpful in certain situations such as lifting materials out of a deep trench or into a high truck. The CX700 has retractable side frames and an optional counterweight removal device for easier transport.

Case also has upgraded its CX330 model, increasing power and improving fuel economy. The engine that now powers the CX330 is fully electronic and uses a high-pressure, common-rail injection system that provides a 5% increase in horsepower and 8% to 10% better fuel economy, according to the company.

Case notes that a number of standard features on the CX700 are upgrades for the CX330, and will be applied to larger Case excavator models moving forward. Key upgrades include improvements for ease of maintenance and serviceability. Both the CX330 and CX700 feature EMS (easy maintenance system) lubricated, impregnated bushings throughout the boom and arm for extended lube intervals of up to six months or 1,000 hours. Engine oil filters are now vertically mounted in the pumphouse access area to allow for easier servicing. An upgraded cooling system and finer fuel filtration capability are additional features on the CX330 that will be incorporated into future models and upgrades.
