Client expectation<\/h4>\n

Each year, out client, a ready-to-use cement, aggregates and concrete manufacturer, undertakes technical stoppages in order to maintain its ovens. Indeed, the cement manufacturer takes advantage of these 3-week stoppages to replace a large number of machines and thus overhaul the dismantled equipment. In order to be totally trouble-free with their running and restarting, he wished to work with a reliable partner who would:<\/p>\n

    \n
  • take responsibility for the overall operation<\/li>\n
  • know how to manage the electrical and mechanical parts of the drive system<\/li>\n
  • provide a technical guarantee for operations allowing secure restarting<\/li>\n
  • comply with the safety regulations<\/li>\n<\/ul>\n <\/div>\n <\/div>\n<\/section>\n\n

    DV GROUP Solution<\/h4>\n

    Satisfied with our expertise and our offer, our client chose to grant us the exclusivity of the replacement \/ overhauling of machines during its technical stoppages. This time, for our fourth collaboration, the experts from our electro-mechanical agency in Saint-Priest were mobilised for 3 weeks to process 19 machines (moto-reducers, moto-ventilators and motors) from 50 kg (2.2 kW) to 5 tons (7.2MW) and to keep to the deadline set by our client.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n
