KONKO’s solutions are used in underground and open-pit mines and in industrial plants in Europe, Asia, North America and Australia. Its cable regeneration workshop for mining, metallurgy and power repairs 1 to 1.5 km of cables a month, restoring the original conductor design by butt welding; according to the company, regeneration costs no more than 20% of the price of a new cable. Steel structures are protected against corrosion, among other methods, by hot-dip galvanising. As an IGMNiR member, KONKO represents the machinery and structural supply base for underground mining, as well as cable regeneration for mining and metallurgy.
