The Cat® 789 Mining Truck is the most popular 193-tonne (213-ton) truck in the mining industry — and for good reason. Developed specifically for high-production mining applications, the 789 simply does its job, no matter the application or conditions. It continues a legacy of durability and reliability while meeting emission standards for any location in the world. It uses less fuel, has expanded safety options and reduces maintenance downtime. It offers fast speed on grade and a high production capability thanks to a payload advantage over the competition. More than 30 new features improve performance and keep operators safe, comfortable and in control. The 789 offers the lowest cost per ton in its size class and high reliability — reducing overall owning and operating costs.
