Mordefroy Levage uses two Demag’s in tandem lift of TGV Locomotive

French crane service provider Mordefroy Levage used two Tadano Demag cranes to lift a 34 tonne high-speed Train à Grande Vitesse (TGV) train in Romilly-sur-Seine, France.

The company used a Demag AC 100-4L and a Demag AC 140 to perform a tandem lift operation, which saw the locomotive delivered to the new Technicentre SNCF maintenance facility.

The 22 metre long train, which was transported to the delivery site by road, had to be unloaded from a lowbed trailer and installed on railway tracks at the facility.

Mordefroy lifted the front end of the TGV with its AC 100-4L, taking on 16 tonnes of the train’s weight at a radius of 13 metres, and the AC 140 to lift the rear end at a radius of 14 metres.

Together the cranes hoisted the TGV 12 metres into the air and, in a synchronised manoeuvre, positioned it precisely over the tracks before lowering it into place. The entire operation was completed in eight hours.

Patrick Mordefroy, general manager at Mordefroy, said, “The two Demag cranes had more than the performance characteristics required for this job, not to mention that they work like a charm together, so it was only natural for us to use them.”

He added, “We owed a lot of it to the reliability and unrivalled performance characteristics of our two Demag cranes, which is why we really consider them to be an invaluable part of our fleet.”
