  • Support structure for suspending a work surface below a girder
    Publication number: 20010037914
    Abstract: A support structure for moveably suspending a work surface from the underside of a bridge includes at least a first clip mounted on each lower web of a pair of parallel bridge girders, a track mounted on each clip, and a scaffold member rollably suspended from the track, the work platform extending between the scaffold members. The scaffold members include a plurality of rollers that roll along the upper surface of each track such that the scaffold members are selectively rollable along the tracks. The clips are securely clamped to the lower webs of the girders such that the rails are securely and unadjustably spaced below the lower webs of the girders.
