Key Specs
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 2008 the success of the 993K is a testament to its heritage. Created from Cat Large Wheel Loader DNA, the roots of performance, durability, comfort and efficiency runs deep. Move more make more with the 993K.
Provides overall greater efficiency, versatility and safety...all at a lower cost.
Highly durable structures achieve multiple lifecycles and withstand the toughest loading conditions.
Unparalleled operator comfort and ergonomics help you get the most from your machine...shift after shift.
