Cat Large Wheel Loaders are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to move more material efficiently and safely. The 990K Millyard Arrangement is designed to meet the demands of millyard applications. The features of the 990K Millyard work together to provide a durable and reliable machine to meet the needs of the modern millyard.
The Cat C27 ACERT engine is built and tested to meet your most demanding applications while meeting Tier 4 Final or Tier 2 equivalent emission standards.
Fully integrated electronic engine controls work in concert with the entire machine to make your fuel go farther.
Use less fuel idling with Engine Idle Shutdown.
Maximized durability with Delayed Engine Shutdown.
Cat Planetary Powershift Transmission
Maximize your uptime with the proven planetary power shift transmission. Improved shift quality, component life and operator comfort with our electronic transmission controls.
Impeller Clutch Torque Converter (ICTC)
Enable your operators to maximize efficiency by varying machine rimpull while putting more horsepower to hydraulics.
Reduced tire wear
Enables full throttle shifts for faster cycle times
Provides smooth approach to the dump target for less spillage and faster cycle times.
Cat Torque Converter with Lock-up Clutch
Eliminates TC losses while lowering system heat
Improves travel speeds
Reduces cycle times in load and carry operations
Enabling maximum productivity and efficiency, all day every day. The 990K systems work hard to save you fuel through advanced technologies. Utilizing On Demand Throttle, operators maintain normal operation with the left pedal and implements while the 990K manages the engine speed.
Provides similar control and feel to our traditional throttle lock feature.
Efficiency of manual throttle and the ergonomics of throttle lock.
Increase efficiency through our Positive Flow Control (PFC) Hydraulic System. PFC has concurrent pump and valve control. By optimizing pump control, hydraulic oil flow is proportionate to implement lever movement.
Fast, productive cycles are enabled by the fully variable implement pump.
Increase fork feel and control through increased hydraulic response.
Consistent performance and efficiency with lower system heat.
Full hydraulic flow down to 1,400 engine rpm enabled by flow sharing technology.
Electro Hydraulic Controls
Operators increase productivity with our responsive implements feature.
Operate comfortably through electronically controlled hydraulic cylinder stops.
Handle easy-to-use soft detent controls.
Conveniently set automatic implement kickouts from inside the cab.
Confident loader operation starts with precise machine control enabled by the 990K's load sensing hydraulic steering system.
Increase efficiency with our variable displacement piston pumps.
Achieve precise positioning for easy loading in tight areas with 35 degrees of steering articulation.
Enhance operator comfort with integrated steering and transmission control functions.
Benefit from extended performance and reliability of your hydraulic system with our advanced filtration system.
The 990K electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator, maximizing the productivity of both.
Cat Product Link™
Cat Product link allows remote monitoring of equipment to improve overall fleet management effectiveness. Events and diagnostic codes, as well as hours, fuel, idle time and other information are transmitted to a secure web based application, VisionLink®. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.
We have worked hard to help our customers and operators perform at their best through our Vital Information Management System (VIMS 3G).
Easy-to-view graphical information display features a large touch screen interface.
Intuitive operation and easy navigation with our enhanced user interface.
Decrease service time by keeping operators informed about machine system malfunction or operation.
Sustainability is designed and built into our 990K's features.
Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.
The 990K is built for multiple lives. To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost.
Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
