Speaking of battery-powered equipment, Díaz Pró added that Caterpillar will only launch this technology at a commercial level once it is able to perform as well as diesel engines. Komatsu Mining Corp., the company cre- ated from the merger of Komatsu and Joy Global, is also in a good position to push its technological developments across a wide variety of machines involved in mining, from the Komatsu trucks and construction equip- ment to the P&H shovels, Joy underground equipment and Montabert drills. Carlos Fonseca, general manager of Komatsu Min- ing Corp. in Peru, gave more details about the SR (Switched Reluctance) technology included in the P&H wheel loaders and the larger Joy underground loaders: "It consists of the ability to recapture energy when you put the brakes on, like in hybrid vehicles, or when you lower the bucket. This energy can be applied to propel the wheels. The feedback we have received is that it is very fuel-efficient and low on maintenance. This technology is targeted to be included in other Komatsu products in the future." Narrow-vein mining The improvement of the market has clearly been felt across the underground spectrum. Indeed, higher base metal prices have dras- tically improved the economics of many mines, encouraging operators to engage in more dynamic budgeting after years of se- vere cuts in investment. The lack of mechanization in narrow-vein operations opened up a business niche that the very large OEMs probably did not find to be large enough for them. Yet, it is a sig- nificant market worldwide. Resemin, a Pe- ruvian manufacturer of underground equip- ment, has specialized in this segment, and is achieving excellent growth rates (50% in 2017). Gonzalo Díaz Pró, general manager, Ferreyros.
