Best built for the toughest conditions.
Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest loading conditions.
Your key to maximum uptime and productivity is our purpose built front and rear frames.
To ensure long life and reliability, solid one piece push beams are through-width, not merely attached to the side of the frame. In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.
Move material more efficiently with improved power and control.
Experience maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.
Building your success begins with a best-in-class transmission designed specifically for mining applications.
Durability and efficiency powering your 844K comes from the Cat C27 ACERT Engine. Optimum performance is built in through the use of a 12 cylinder, direct injection design.
Lower your cost per ton utilizing advanced ICTC and RCS for modulated rimpull.
Productivity enabling you to move more and make more.
