The Cat C18 ACERT engine is built and tested to meet your most demanding applications while meeting Tier 4 Final/Stage IV OR Tier 3/Stage IIIA Equivalent OR Tier 2/Stage II Equivalent emission standards.Fully integrated electronic engine controls works 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

Featuring all new Advanced Productivity Electronic Control Shifting (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

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

Economy Mode

Enabling maximum productivity and efficiency, all day every day. The 988K 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 988K 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 operation.Reduced fuel consumption by up to 20% compared to the 988H.

Best built for the toughest conditions.

Robust Structures

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions. Full box-section rear frame resists torsional shock and twisting forces. Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame. Axle mounting has been optimized for increased structural integrity. Lower hitch pin, frame plate, and bearing size have been increased for longer life.

Lift Arms

Excellent visibility to the bucket edges and work area through a Z-bar design. High load stresses are absorbed by the solid steel lift arms. Enhance strength in key pin areas through the use of one piece castings. Stress relieved lift arms increase durability and lengthen time to repair.

Front Linkage

To ensure long life and reliability, the linkage pin joints feature a greased pin design with an auto lube system attachment available from the factory.

Move material more efficiently with improved power and control.

Steering and Transmission Integrated Control System (STIC™)

Experience maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever. Simple side-to-side motion turns machine right or left, minimizing operator movements. Easy to operate finger controlled gear selection. Smoother, faster cycles and less operator fatigue through the use of low effort integrated controls.

Cat Planetary Powershift Transmission

Building your success begins with a best-in-class transmission designed specifically for mining applications. Consistent, smooth shifting and efficiency through integrated electronic controls that utilize Advanced Productivity Electronic Control Strategy (APECS). Long life and reliability through heat treat gear and metallurgy. Four forward and three reverse speeds to match your application.

Cat C18 ACERT Engine

Durability and efficiency at the heart of your 988K comes from the Cat C18 ACERT Engine. Optimum performance is built in through the use of a 6 cylinder, four-stroke design.Optimized performance and quick engine response with an electronic control module.Reliable efficiency with complete control over injection timing, duration and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).Extended engine life and improved fuel efficiency with reduced rated speed.Designed to meet Tier 4 Final/Stage IV OR Tier 3/Stage IIIA Equivalent OR Tier 2/Stage II Equivalent emission standards.

Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS)

Lower your cost per ton utilizing advanced ICTC and RCS for modulated rimpull. Reduce tire slippage and wear by modulating rimpull from 100 to 25 percent while depressing left pedal. After 25 percent rimpull is achieved the left pedal applies the brake. Reduce the potential for wheel slippage without reducing hydraulic efficiency with RCS. Improve fuel efficiency in certain applications with our lock-up clutch torque converter providing direct drive.

Productivity enabling you to move more and make more.
