Case
The CX800B excavator features an electronically controlled, common rail Tier 3-certified 15.7L Isuzu engine which delivers 532 net hp. The common rail fuel injection system, combined with the redesigned hydraulic system, delivers increased fuel efficiency over the previous model. The CX800B features regenerative hydraulics on the boom and arm, as well as the bucket curl, which speeds the cycle time required to get a bucket of dirt. Larger-diameter hydraulic cylinders deliver a breakout force of 74,187 pounds. The excavator cab features a seat that adjusts independently of the joystick controls for improved operator comfort and ergonomics. The CX800B excavator also features memorized operator adjustment, which automatically adjusts to the last settings selected by the operator. An optional air seat makes the operator even more comfortable. The CX800B features a “green plug” that provides an easier, cleaner and greener engine oil change. The engine oil filter, remotely located in the pump house, is easy to change without the need to go underneath the machine. The hydraulic oil filter provides 100-percent continuous flow filtration of all hydraulic oil on the return line. Flip-open service panels provide easy access to virtually all key components.
