French heavy lift and transportation company Scales SAS used an Enerpac JS-250 jack-up gantry system to lift and lower a tunnel-boring machine (TBM) weighing 880 tonnes.
Named Koumba, the TBM is 8.9 metres in diameter and 11.4 m long. It is being used in the latest phase of the Paris Metro extension project.
Enerpac’s JS-250 jack-up gantry has a capacity of 250 tonnes per tower and the hydraulics are self-contained. Four towers were used for the gantry setup. Loads are lifted in increments as steel barrels are stacked together to form lifting towers.
