Case CX700 And CX330
The company of Case has done it again, by introducing yet another spectacular excavator, the CX700, which weighs in at 70 metric tons and represents a new size for Case, fitting perfectly between the CX460 and CX800 models. Case has also taken advantage of Tier 3 technologies and upgraded the CX330, increasing the power and improving fuel economy, all while adding features that will enhance comfort for the operator and simplify maintenance.
Power The CX700 is a powered by a high performance, fuel efficient Isuzu engine that is completely Tier 3 certified. With an operating weight of 153,400 lbs. and over 400 HP, the CX700 is capable of digging to 31 feet 11 inches with reaches up to 46 feet 11 inches.
The frame for the CX700 is based on the larger CX800 to ensure optimum durability and reliability, especially given the powerful performance specs the machine calls for.
New to the Case CX700 is a switch that will allow you to give priority to either the boom or the swing functions. The CX700 also offers retractable side frames and an optional counterweight removal device, which makes transporting easier than ever before.
More durable The Isuzu engine that powers the CX700 is fully electronic and uses a high pressure rail system that provides a 5% increase in HP and also gives the excavator 10% better fuel economy.
Several enhancements have been made to the CX330 upon releasing the CX700, including the overall reliabilty and durability of the machine, which includes the strength of the front idlers by beefing up the thickness and design of the center hub and improving the track seal design for increased life.
Upgrades Several of the features that come standard with the CX700 are upgrades for the CX330 that will also be applied to other large Case excavator models that move forward. The key upgrades include ease of maintenance and servicing. Both the CX330 and CX700 models feature an easy maintenance system, lubricated bushings throughout the boom and arm, which provides extended lube periods of up to 1,000 hours. The engine oil filters are now mounted vertically in the pump house access area, which allows for easier access and servicing.
The addition of a modified oil drain plug with a check valve will make it easier than ever to change oil. Both the CX330 and CX700 both offer finer fuel filtration, up to four microns, which provides increased uptime and improved fuel performance.
The upgraded cooling system features a design that reduces the stacking of coolers for better cooling efficiency and also improves access to ease the removal of debris. In addition to this, the Case CX700 also features a hydraulically driven, thermostat controlled reversible fan for improving the cooling of the engine and easy cleanout of the materials.
