Omexom dismantles a 70-year-old pylon by helicopter in the province of Liege

As part of the rehabilitation of existing sites, Omexom in Belgium was awarded a contract by Elia in July, to dismantle a high-voltage pylon dating from 1951 using a helicopter. This type of intervention is usually carried out from the ground using a crane, but the location of the pylon in question near the Carmeuse quarry did not allow for this configuration. The intervention of a helicopter and Omexom teams was therefore requested. This operation was carried out efficiently, with safety always a priority.
