Case Construction Equipment today announced the upgrade of its largest excavator – the CX800B – to its B Series line of excavators. The new CX800B features increases in fuel efficiency and productivity, as well as improved operator comfort and ease of maintenance.
The excavator also features an electronically controlled, common rail Tier 3-certified 15.7L Isuzu engine which delivers 532 net hp (397 kW).
The CX800B is available in standard and mass excavation configurations, making it ideally suited for a variety of quarry, road and bridge and other applications requiring heavy muscle and long reach.
Increased fuel efficiency and productivity
The common rail fuel injection system, combined with the redesigned hydraulic system, delivers increased fuel efficiency over the previous model.
“The CX800B delivers increased fuel efficiency and productivity, which results in more cubic yards of material per gallon of fuel,” said Mitchell Blake, Case brand marketing manager.
“Our first customer is operating the CX800B three shifts a day in a mining operation,” Blake said. “In December, they ran the machine for more than 600 hours. The foreman’s not only amazed at its productivity, but also at the fuel efficiency. He said that, compared to a competitive excavator model, the CX800B will save more than $100,000 a year in fuel.”
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 lb (330 kN).
Quiet, comfortable cab
The sound levels inside the isolation-mounted cab are among the quietest in the industry, even at full throttle. Reinforced tubular structures in the cab help dampen vibrations.
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.
Ease of maintenance
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.
The CX800B has an operating weight of 178,575 lb (81,000 kg), a bucket capacity of 5.91 yd3 (4.52 m3), a bucket digging force of 96,668 lb (430 kN) and a maximum dig depth of 35 feet (10.66 m).
In addition to the CX800B, the full line of Case B Series excavators includes the CX130B, CX160B, CX210B, CX240B, CX290B, CX350B, CX470B and CX700B. Case also produces the CX75, CX80, CX135 and CX225 minimum swing excavators, as well as a full line of compact excavators.
