994K Large Wheel Loaders

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 at a lower cost per ton.
Introduced in 1990, the 994 has become the top customer choice in its size class for over 25 years. Focused on helping our customers succeed, we have continued to build upon each new series' legacy of reliability, safety, operator comfort, serviceability and sustainability.
All images included in this Specalog show a U.S. EPA Tier 1/EU Stage I Equivalent configuration. It's important to note that the Tier 4 Final/EU Stage V Equivalent will have some physical differences, including the presence of a DEF tank.

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 to maximize life of mounted components.
Frames utilize castings in key areas to maximize frame durability and optimize efficiency.
Rear axle mounting to frame optimized to better disperse loads for increased structural integrity.

Lift Arms

Your key to maximum uptime and productivity is our field-proven 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.
Enhanced strength in key pin areas through the use of one piece castings.
Stress relieved lift arms increase durability.

Front Linkage

To ensure long life and reliability, the linkage pin joints feature a greased pin design and standard automatic lubrication system

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

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.
