No matter what their interests—surface or underground, hard rock or soft rock—MINExpo visitors will find the machines and technology at the Caterpillar exhibit to help them mine and move minerals safely and productively. Caterpillar will reveal a number of innovative mining systems and machines. For example, the new AD60 underground truck, with 60-tonne capacity, and the new R3000H underground loader, with 20-tonne payload capability, represent the largest such machines Caterpillar has ever made and promise to boost production and cut costs in high capacity hard rock mines. Support equipment will also be on display at MINExpo, including new Cat CT660 vocational truck equipped as a service truck. The CT660, available only in North America, is the first Cat branded on-highway truck that can be fitted with many different bodies to serve the needs at hand. Additional support equipment includes the recently introduced C175-20 generator set, which produces the greatest output, as much as 4 megawatts, of any single high-speed diesel generator set available on the market.
