Conveyor / Gantry





         CONNECTIONS


         ASSESS

          ●     Corroded, Missing or loose bolts.

          ●     Distorted or deflected connections
          ●     Poor quality or damaged welds
























         TRUSS GANTRY FRAME STRUCTURE


         ASSESS


           ●    Damaged or missing structure elements
           ●    Blocked or damaged flexible connection (sliding, hinged, bearing)
           ●    Excessive deflection or misalignment
           ●    Non controlled modifications





                                                         modified beam

















         NOTE: The maximum deflection allowed
         in a horizontal truss gantry = Span
         length / 200

         Surveying can be used to assess and
         monitor deflection or displacement
