R1700 Underground Mining Loader

When it came time to redesign the Cat® R1700 Underground Loader, the goal was simple: add value, power and performance, and keep safety at the core. And we succeeded. With each cycle, the R1700 hauls 20% more material than its predecessor and is highly aggressive in the pile. It loads, climbs, hauls and dumps faster. And it’s factory ready for the latest technologies, including fully autonomous haulage, which takes safety and efficiency to a new level. The R1700 is infused with features to keep people safe. It offers three engine emission options, including one that meets Stage V standards, and can be tailored to your mine’s ventilation requirements. A clean-sheet redesign, the R1700 loader leverages engineering talent from across Caterpillar to create the next generation of productive underground loading.
