Upgraded Cat 990K wheel loader has a rated payload of 17.5 tons, up from 16.5 tons on its predecessor H Series model. The loader can be paired with Cat 773, 775 and 777 haul trucks, and will load a 775 in four passes. The Tier 4-Final Cat C27 ACERT engine has 699 horsepower, 11 percent more than the previous model. An impeller clutch torque converter uses a lock-up clutch for direct drive, which allows operators to balance rimpull and hydraulic power. The redesigned cab features noise suppression that delivers a sound level of 69.9 dB(A), and has the Cat Vital Information Management System, which provides customizable operator profiles, a cycle timer, and an integral Payload Control System. A remote panel houses a stairway light switch, engine shutdown switch, and lockouts for the transmission and engine starter. A second panel provides access to the battery disconnect switch and a jump-start receptacle. Performance Series Buckets are available in sizes ranging from 11.25 to 13 cubic yards. Additional fuel savings are provided by ECO Mode on-demand throttle, engine-idle shutdown system, and engine-idle kickdown/auto-resume system.
