Proven Reliability
Integrated Steering and Transmission Control System (STIC™) Benefit from maximum responsiveness and control with the STIC system, which combines direction selection, gear selection, and steering into a single lever. A simple movement of the lever to the left or right allows for turning left or right, minimizing driver effort. Ultra-easy gear selection at the touch of a finger. Smoother, faster cycles and less fatigue for operators thanks to integrated controls that require minimal effort. Cat Planetary Powershift Transmission Your success relies on a superior transmission specifically designed for mining applications. Smooth and efficient gear shifting thanks to integrated electronic controls. Longevity and reliability ensured by heat treatments and metallurgical processes on the gears. Three forward gears and three reverse gears to adapt to all your applications. Cat C27 Engine The exceptional lifespan and efficiency of your 990K come from its Cat C27 Engine. Its 12 cylinders with direct injection naturally provide optimal performance. Optimized performance and quick engine response thanks to an electronic control module. Reliable efficiency with perfect control of timing, duration, and injection pressure thanks to the electronically controlled mechanical unit injectors (MEUI™). Increased engine lifespan and improved energy efficiency thanks to lower rated speed. Available in two versions: one compliant with Tier 4 Final emissions standards and another compliant with emissions standards equivalent to Tier 2. Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS) Reduce your cost per ton by using advanced ICTC and RCS systems to control rim effort. Reduce tire slippage and wear by controlling rim effort from 100% to 25% using the left brake pedal. Once the position corresponding to a 25% reduction in rim effort is reached, the pedal is used for braking again. Decrease the risk of wheel slippage without reducing hydraulic efficiency of the machine thanks to RCS. Improve energy efficiency in certain applications with the lock-up torque converter allowing for direct drive.
Performance and productivity
Positive Flow Control Hydraulic Circuit Increase your efficiency with our positive flow control (PFC) hydraulic circuit. The PFC circuit features dual pumps and valves control. Optimizing the pump control allows for the hydraulic oil flow to be adjusted proportionally to the movement of the equipment lever. Fast and productive cycles are activated by the fully variable equipment pump. Improve bucket sensitivity and control through better hydraulic response. Consistent performance and efficiency with lower circuit heating. Maximum hydraulic flow at a reduced engine speed of 1600 rpm. Electro-Hydraulic Controls Increased equipment responsiveness allows operators to enhance their productivity. Work comfortably with electronically controlled hydraulic cylinder stops. Enjoy smooth and easy-to-use controls. Easily activate automatic equipment disengagement from inside the cabin. Steering Circuit Safe loader operation starts with precise machine control. That's why we equipped the 990K Wheel Loader with a load sensing steering circuit. Increase your efficiency with our variable displacement pumps. Achieve precise positioning for easy loading in tight workspaces with a 35-degree steering angle. Enhance driver comfort with integrated steering and transmission controls. Filtration System Benefit from improved performance and reliability of your hydraulic circuit with our advanced filtration system. Return screens to the tank. Hydraulic oil cooler return filter. Pilot filter. Return screens inside the hydraulic tank. Axle oil cooler screens according to equipment.
Mastery and driving comfort
More efficient and comfortable work for drivers thanks to a cabin inspired by our customers. Entry and Exit Easy access to the cabin thanks to its new ergonomic design. Foldable armrest/STIC steering. Reduced access ladder angles. Standard ladder lighting. Comfort Cat Series III Seat Improve driver comfort and reduce fatigue with the Comfort Cat Series III seat. Mid-height backrest and ultra-thick padded cushions. Air suspension system. Levers and seat controls within reach. Adjustable in 6 directions. Equipment control panel and STIC steering mounted on the seat and moving with it. 76 mm (3 in) wide retractable seat belt. Optional heated and ventilated seats. Control Panel The ergonomic positioning of switches and information screens provides drivers with better comfort throughout the day, every day. Large backlit membrane switches have LED activation indicators. Switches have ISO symbols for quick function identification. A two-position toggle switch activates the electrohydraulic parking brake. Driving Station Improve your drivers' productivity with the clean and comfortable environment of our cabins. Enjoy the low level of vibrations achieved through cabin mounts and seat pneumatic suspension. Maintain the desired temperature inside the cabin with automatic temperature controls. Pressurized cabin with filtered air. Reduced noise level at 69 dB(A). Conveniently positioned storage tray/lunch basket at ground level.
Long-term profitability and long lifespan
Robust Structures Boost your results with ultra-resistant structures capable of performing multiple life cycles and supporting the most difficult loading conditions. The fully enclosed rear chassis resists both torsional forces and shocks. The extra-robust anchorages of the steering cylinders efficiently transmit the steering loads to the chassis. The axle assembly has been optimized for increased structural integrity. Handling Arms Excellent visibility on the bucket blades and work area thanks to the Z-linkage. Absorption of high-stress loads by solid steel handling arms. Increased resistance in key areas thanks to the use of monobloc castings. Long lifespan and increased intervals between repairs thanks to stress-free lifting arms. Front Linkage To ensure optimal lifespan and reliability, the axis joints of the linkage are designed with a factory-mounted automatic lubrication system.
Power and efficiency
C27 Cat Engine The C27 Cat Engine is designed and tested to meet your most demanding applications while complying with Tier4 Final emission standards OR equivalent to Tier2 standards. The fully integrated electronic engine controls work in conjunction with the entire machine for increased fuel efficiency. The engine idle shutdown function reduces fuel consumption at idle. The engine delayed shutdown function ensures longer lifespan. Cat Planetary Powershift Transmission Optimize your productive time with the proven Cat Planetary Powershift transmission. Gear changes, component lifespan, and driving comfort are optimized through our electronic transmission controls. Modulation Clutch Torque Converter (ictc, Impeller Clutch Torque Converter) This device allows drivers to optimize efficiency by varying the effort at the machine rim while increasing hydraulic power. Reduced tire wear. Full throttle gear shifts for shorter cycle times. Smooth approach to the dumping area to limit spillage and ensure shorter cycle times. Cat Lock-Up Torque Converter Eliminates torque converter losses while reducing circuit temperature. Improves travel speeds. Reduces cycle times in loading and hauling applications. Economy Mode Ensures optimal productivity and efficiency throughout the day, every day. The advanced technologies of the 990K model systems allow you to save fuel. With on-demand acceleration, the 990K automatically manages the engine speed while the driver focuses on the left pedal and equipment control. Provides the driver with the same control and sensitivity as the traditional throttle lock function. Combines the efficiency of manual acceleration with the ergonomics of throttle lock.
Reduced maintenance and upkeep
Because the very design of the 990K model allows for reduced downtime, it will be the key to your success. Safe and convenient maintenance thanks to grouped maintenance points, accessible from the ground or the platform. Swinging doors located on both sides of the engine compartment facilitate access to daily maintenance checkpoints. Environmentally friendly drain valves make maintenance easier and prevent spills. Reduce your downtime with notifications from our VIMS management system, allowing drivers and technicians to solve problems before they even occur. Ground-level access to transmission control valves.
