The new Cat 994K Wheel Loader is Caterpillar’s largest wheel loader and handles an increased payload compared to its predecessor, the 994H. The standard 994K carries 45 t per pass, and the high lift version moves 42 t per pass, 18% and 20% more, respectively, than the previous model.
The 994K loads mining trucks in the 250, 200 and 150 t classes in one less pass than the previous model. The high lift configuration is a six-pass match with the Cat 793 mining truck, and the high lift as well as the standard configuration loads the Cat 789 in five passes. The standard configuration loads the Cat 785 in four passes. More engine power, increased hydraulic flow, greater breakout force and rimpull, and improved lateral stability are also developments that have been made to the new loader.
The new 994K also offers options to expand its application range and versatility. The new high ambient package is available to equip the loader for operation in higher temperatures, and the standard cooling package offers improved cooling compared to the previous model. An optional fuel tank holds enough fuel to operate the loader for 24 hours without refueling. New high performance buckets in a wide range of capacities are optimised for the 994K linkage kinematics. The new bucket design has an extended floor, larger radius and angled side bars for fast loading, high fill factors and good material retention.
A number of efficiency improvements, such as the electronically controlled and hydraulically driven cooling system fan, help keep operating costs down. The new engine air filtration system delivers three times the life of the previous system.
The new 994K also features safety and operator health enhancements, such as a reduced stair angle for easy access and egress, a Cat Deluxe seat and four-point seat belts. The operator has increased visibility with new mining mirrors, optimized LED lighting and an improved camera for greater site awareness. The loader also delivers reduced sound in the cab to help fight operator fatigue, and increased cab air pressurisation and filtration keep dirt out.
Engine oil change intervals are 500 hours minimum, and all routine service points are conveniently located on the left side of the loader. Hydraulically driven auto lube handles linkage greasing. Superior hydraulic system filtration helps ensure long life and optimum performance, and durable LED lights extend service intervals. Modular design makes field assembly and component replacements faster.
The 994K Wheel Loader will be commercially available in the first quarter of 2016.
