793D

Mining Trucks

The Cat® 793 Mining Truck was introduced more than three decades ago, and every model has continued to deliver excellent speed on grade, class-leading payload and long life — making it one of the most popular trucks in the mining industry. The 793D is no exception. The 793D delivers more power and performance for an increase in productivity, a class-leading empty weight that leads to optimized payload, and longer life for high operating hours, reduced costs and the opportunity to rebuild for multiple lives. The 793D is available in five configurations, making it the ideal choice for a wide variety of applications. It hauls more every load, every cycle and every shift. And it delivers a better bottom line to the most important mine in the world: yours.
