The Case CX130B excavator has been upgraded to Tier-3 certification with an electronically controlled, 95-horsepower (net) Isuzu engine having a common-rail fuel system. According to Case, the new machine’s common-rail fuel-injection system and redesigned hydraulic system enhance fuel efficiency by 15 percent. Hydraulic-system refinement for the 27,800-pound CX130B includes more hydraulic horsepower, plus routing of return oil (normally flowing directly to the tank) to combine with pump flow in order to reduce overall cycle time. Sound levels inside the cab, says Case, are as low as 68.5 dB(A).
