Overview

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.
