Power and Efficiency
C18 CAT® Engine The Cat C18 Engine has been designed and tested to meet your most demanding applications while complying with Tier 4 Final EPA standards for the United States and Stage IV for the European Union, equivalent to Tier 2 standards. The fully integrated electronic engine controls work in conjunction with the entire machine for increased fuel efficiency. The engine idle shutdown feature reduces fuel consumption at idle. The delayed engine shutdown feature ensures longer life. Cat Planetary Powershift Transmission The all-new transmission controls with Advanced Productivity Electronic Control Shifting (APECS) provide extra power on slopes and save fuel by pulsing during gear shifts. Impeller Clutch Torque Converter (ICTC) This device allows operators 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 dump 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 988K systems allow you to save fuel. With on-demand acceleration, the 988K automatically manages engine speed while the operator focuses on the left pedal and equipment control. Provides the operator with the same control and sensitivity as the traditional throttle lock function. Combines the efficiency of manual acceleration with the ergonomics of throttle lock. Reduces fuel consumption by nearly 20% compared to the 988H model.
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. The lower articulation axis, frame plate, and bearing size have been increased for longer life. Handling Arms Absorption of high-stress loads by solid steel handling arms. Increased strength 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 linkage axis joints are designed with a factory-mounted automatic lubrication system.
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 depends on a superior transmission specifically designed for mining applications. Smooth and efficient gear shifting thanks to integrated electronic controls that use the Advanced Productivity Electronic Control Strategy (APECS). Longevity and reliability ensured by heat treatments and metallurgical processes on the gears. Four forward gears and three reverse gears to adapt to all your applications. Cat C18 Engine The exceptional lifespan and efficiency of your 988K Wheel Loader come from its Cat C18 Engine. Its 6 four-stroke cylinders 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 mechanically actuated unit injector system (MEUI™). Increased engine lifespan and improved energy efficiency thanks to lower rated speed. Compliant with Tier 4 Final EPA emissions standards for the United States and Stage IV for the European Union, equivalent to Tier 2 standards. 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 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. Flow distribution technology allows for maximum hydraulic flow up to 1400 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 our 988K Wheel Loader with a load sensing hydraulic steering circuit. Increase your efficiency with our variable displacement pumps. Achieve precise positioning for easy loading in confined spaces with a 37-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.

Control Panel The ergonomic positioning of switches and information display 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 71dB(A). Conveniently positioned storage tray/lunch basket at ground level.
Reduced maintenance and upkeep
Because the design of our 988k 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. Swiveling radiator with 6 fins per inch radiator bundles for easy cleaning. Automatically reversing fan to keep the cooling circuit free of debris. Environmentally friendly drain valves facilitate maintenance and prevent the spillage of potentially hazardous contaminants.
