Crane trestle is under construction at smelting shop of Kola MMC

Construction of trestle for crane altitude change is in the progress in the main building of the SmeltingA pyrometallurgical process performed at high temperatures enabling the complete melting down of the processed material.Go to the glossary Shop of Kola MMCMining and Metallurgical CompanyPublic Joint Stock Company "Mining and Metallurgical Company "Norilsk Nickel"Go to the glossaryGo to the glossary (NornickelPublic Joint Stock Company "Mining and Metallurgical Company "Norilsk Nickel” and its subsidiariesGo to the glossary subsidiary) in township of Nickel. The engineering structure is necessary for repair of main hoisting-and-conveying equipment.

Thee overhead cranes operate in main aisle of the Smelting Shop. They are responsible for charging of materials into converters and discharging of converter-matte produced by pyrometallurgical processing.

According to the schedule, every hoisting device has to undergo an operating repair and three routine maintenance procedures. Problems emerge when the middle crane has to be repaired. When in the maintenance area it blocks one of the edge cranes thus obstructing engagement of the last in the production process. Construction of the crane trestle will eliminate these downtimes.

One of the cranes will be jacked up with the lifting mechanism to make way for the others to come back from repair area to central aisle of the Smelting Shop. To the moment, foundation for crane trestle was completed and steelwork erection was started at the smelting shop. Trestle will help to increase freight traffic within the main aisle and improve speed of converters charging.
