It was used to move the Empire State Building in New York City. After tunnelling under the foundations, hydraulic jacks were placed beneath the building. Then the jacks were raised.

Unfortunately, due to underground subsidence, the gantry collapsed taking with it the building, trapping two reporters underneath the rubble.
