New 992K High-Lift Offers Greater Truck-Loading Flexibility
Created 12/01/2010, 11:22:32 am
The 992K High-Lift has a rated payload capacity of 21 tons (19.1 t). Assuming 100 percent bucket-fill factors, maximum material densities for available buckets, smallest to largest, are 3,000, 2,800 and 2,625 pounds per cubic yard (1 780, 1 660 and 1 560 kg/m3). Hinge-pin height at full lift is 24 feet 9 inches (7 545 mm). Equipped with a 14-cubic yard (10.7 m3) bucket, dump clearance under the teeth (at full height and 45-degree discharge angle) is 17 feet 2 inches (5 232 mm); equipped with 15- and 16-cubic yard (11.5- and 12.2-m3) buckets, dump clearances are 16 feet 11 inches (5 156 mm) and 16 feet 9 inches (5 105 mm), respectively.
At 21 tons (19.1 t), the 992K High-Lift is swinging less weight than its predecessor, the 992G High Lift. Front linkage design changes have reduced rated payload slightly but have improved pin casting and linkage durability significantly. For applications requiring greater payload capacity, the standard linkage 992K has a rating of 24 tons (21.7 t), and for applications requiring greater production, Caterpillar offers the larger 993K with a payload rating of 27.5 tons (24.9 t) for the High Lift and 30 tons (27.2 t) for the Standard Lift.
The design of the 992K High-Lift fabricated single boom incorporates castings in high-stress areas for long-life durability. For easier maintenance management, the high-lift system shares a significant number of parts with the standard-lift 992K, including lift and tilt cylinders, position sensor and harness, hydraulic lines and buckets.
K Series™ features aid productivity, maintenance, safety
Additionally, the 992K High-Lift features many improvements introduced with the standard lift model. Boosting productivity is Positive Flow Control (PFC) hydraulics—the next generation of load-sensing hydraulics. Additional sensors at the pumps provide enhanced responsiveness that the operator can feel and use.
The 992K also offers innovative solutions to ease maintenance and boost reliability. The Cat exclusive sleeve bearing pins eliminate the need for daily greasing of the front linkage, and the next generation modular radiator (NGMR) has copper fins for superior heat exchange capabilities. The design minimizes space required and allows enhanced sight lines to the rear. Centralized service centers and ground level access points including the bumper service center and optional fluid service center also ease maintenance and reduce exposure to falls.
The loader design also emphasizes operator safety and comfort. A trainer seat is standard equipment. The optional rearview camera increases the view behind the machine as do optional, heated rearview mirrors.
