86 E&MJ • AUGUST 2018 Resemin produced 92 units last year, and the company has ex- pectations to reach the 150-unit/year mark soon. "Our most suc- cessful product lines are the roof bolters and the Muki," said James Valenzuela, CEO and chairman of Resemin. "There is now greater demand for equipment for smaller tunnels of three by three meters. The Muki is constantly described as a game-changer, because it has four applications: drilling, scaling, roof bolting and cut-and-fill min- ing. It can quadruple productivity compared to a manual drill." Another important milestone for Resemin's corporate growth was its purchase of Schopf, a Stuttgart-based manufacturer of un- derground loaders. With this acquisition Resemin received all the engineering capability of Schopf as well as the brand, and it will begin manufacturing Schopf loaders in Peru – initially the 3.5-mt payload model, then will progressively move up the product range to the 18-mt payload loaders. Valenzuela said: "We have a complete line of products for underground mining, and the loader market is three times the size of the market for drilling rigs. It is an enormous growth opportunity for us." Automation and drives Another important component in mobile machines and industrial equipment is the drives. Bosch Rexroth, a German company with a leading position in hydraulic drives, has been expanding its service capability in Peru over the last years through the acquisition of a lo- cal distributor and the setting up of a new service shop. Now oper- ating as a new legal entity in Peru, the company will continue capi- talizing on the after-market opportunities (many mining machines arrive in Peru with Bosch Rexroth components already installed), but will also push for the introduction of new solutions locally. Kai Rothgiesser, general manager of Bosch Rexroth, explained that the company sees a lot of opportunity in Industry 4.0: "By recording all the parameters of the different machines and com- ponents, you can make sure that the operation is running at an optimal level and that you can anticipate maintenance. These sen- sors, and the wiring and software associated to them, are not a big investment for the client if you compare it with the benefits you can obtain." Mining already represents 50% of Bosch Rexroth's business in Peru. While Peru's large fleets of mining machines will continue to present significant opportunity for the company's hydraulic drive business, it is in the processing plants that the company sees greater room for development in the automation area: "Mobile machines are closed systems. The plants, however, include many components from different brands. The feeders and conveyors, for example, are huge investments that use a big amount of drives, so there is an opportunity for us to come in," concluded Rothgiesser. Detonating cord.
