The Cat® 797F large mining truck is now available in a fuel-efficient configuration that meets U.S. EPA Tier 4 Final emissions standards.
Through more than 16 000 hours of successful pilot machine operation and 100 000 hours of production truck operation in Tier 4 configuration, the system has proven its ability to deliver strong performance and greater fuel efficiency compared to the Tier 2 797F in most applications.
The 797F Tier 4 Final is equipped with an exhaust aftertreatment system featuring selective catalytic reduction (SCR), which uses diesel exhaust fluid (DEF) to lower NOx emissions. This Cat emissions platform is proven through more than 20 million operating hours in the field. To maintain superior reliability, the 797F aftertreatment system uses less than 11% new content. Designed for easy serviceability with readily accessible components, the modular aftertreatment system is aligned with truck preventive maintenance intervals to maintain high availability.
The truck in the 400 t size class, the 797F, is powered by the 4000 hp (2 983 kW) Cat® C175-20 engine, available with optimized fuel maps for customers focused on the lowest fuel burn, Tier 2 equivalent rating, and now Tier 4 Final.
