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.
