LOADING HAULING Cat 988K Wheel Loader Features Efficient New Loader Linkage Introduction of the seventh‐generation Cat 988 Wheel Loader, the new 988K, marks the 50th anniversary of the 988 deliver‐ ing reliable, profitable performance for worldwide customers. Designed as an optimum loading tool for Cat construction and mining trucks, the 988K features redesigned loader linkage, worldwide engine configurations, drive train modifications, redesigned cab, and enhancements in safety and serviceabil‐ ity. The 988K builds on the premium features of previous models to set new standards for customer value. Caterpillar displayed the new 988K at this year's bauma trade show in Germany; however, the loader will not be available commercially until August this year. The Cat C18 ACERT engine powers the 988K and is available as a Tier 4 Final/Stage IV version (using selective catalytic re‐ duction to control nitrogen‐oxide emissions), and as a Tier 2/Stage II version for less regulated regions. Electronic fuel control ensures optimum performance and throttle response, delivering up to 20 percent greater fuel efficiency, compared with the 988H. Additional fuel savings accrue with the 988K ECO Mode (on‐demand throttle), engine‐idle shutdown sys‐ tem, and engine‐idle kickdown/auto‐resume system. Greater fuel efficiency and lower emissions significantly reduce the carbon footprint. The patented Optimized Z‐bar loader linkage replaces the 988H mono‐boom design and expands 988K versatility in small quarries and underground applications. The new de‐ sign, using solid steel lift arms in either a standard or high‐lift configuration, reduces machine height at maximum lift yet in‐ creases dump clearance. The design also shortens machine length for greater maneuverability. The new linkage combines with durable, precisely designed Cat Performance Series buck‐ ets to enhance production potential. The exclusive Cat impeller clutch torque converter uses a lock‐ up clutch, providing direct drive to boost fuel economy, trim cycle times and reduce heat, especially in load‐and‐carry ap‐ plications. The system allows operators to balance rimpull and hydraulic power for optimum loading efficiency, and the Automatic Retarding Control (ARC) system utilizes the op‐ tional compression brake to maintain desired downhill speeds and reduce service brake wear. Positive Flow Control imple‐ ment hydraulics use a variable displacement, electronically 988K WHEEL LOADER SPECIFICATIONS Cat C18 ACERT 492 hp (362 kW) 111,400 lb. (50 530 kg) 8.3-10.7 cu. yd.
