Caterpillar - Cat

988K Wheel Loader

Caterpillar claims the 988K wheel loader -- the seventh generation of its 988 -- is 20 percent more fuel efficient than its predecessor, and can get more than 5 percent additional fuel economy operating in a new ECO mode that sacrifices no production. Key changes include Z-bar loader linkage replacing the mono-boom, lock-up torque converter, APECS transmission shift strategy, flow-sharing hydraulics, and safety enhancements.

  • Cat C18 ACERT Tier 4 Final/Stage IV engine; uses selective catalytic reduction
  • Also available in Tier 2/Stage II version for less-regulated regions
  • Electronic fuel control delivers up to 20 percent greater fuel efficiency compared to 988H; additional fuel savings with ECO Mode, engine-idle shutdown system and engine-idle kickdown/auto-resume system
  • Cat impeller clutch torque converter uses lock-up clutch to balance rimpull and hydraulic power; provides direct drive to boost fuel economy, trim cycle times and reduce heat
  • Automatic Retarding Control system maintains desired downhill speeds
  • Positive Flow Control implement hydraulics use a variable displacement, electronically controlled pump to precisely apportion oil flow based on control lever movement
  • Redesigned cab sound levels reduced from 74.2 dB(A) in the 988H to 71.1 dB(A)
  • Power rating: 492 hp
