  • the method of operation comprises a method for mounting a crossbeam 1 on a supporting structure 15, alternatively on an anchor rail 14 arranged thereon, the crossbeam 1 being formed by means of a top flange 2 and a bottom flange 3 as well as a plurality of webs 4 connecting the top flange 2 and the bottom flange 3 , in that a plurality of suspension points A are provided at intervals on the top flange 2, that a connecting element 6 is then arranged on the top flange 2 at each suspension point A and that subsequently each connecting element 6 is releasably connected to the structural structure 15 or the anchor rail 14.
  • the suspension points A and thus the connecting elements 6 can be provided on the upper flange 2 at equal distances from each other.
  • a cross member 1 with another, identical cross member 1 'by means of coupling elements 16 lined up, are releasably connected.
  • the cross member 1 ' is analogously connected to the traverse 1 at the suspension points A by means of the connecting elements 6 with the supporting structure 15 or the or an arranged on the supporting structure 15 anchor rail 14.
  • At least one anchor rail 14 is fixedly arranged on the supporting structure 15 and the connecting elements 6 of the crossbar 1, 1 'are detachably connected to the anchor rail 14.
  • the upper flange 2 at each end, each with a gear mechanism 21, 23, 24 or 21 to 24 on the respective associated plate 24 with connecting elements 6 with the supporting structure 15, alternatively the arranged on the supporting structure 15 anchor rail 14 (Halfen rail) are releasably connected ,
  • the end faces on the top flange form the suspension points of the traverse 1 in this embodiment.
  • a traffic load F can be attached to at least one stopping point (lower chord 3) with stop means 7.
  • the lower chord 3 remains substantially parallel, ie linear to the upper chord 2.
  • each suspension point A by means of one, a plate 24 comprehensive gear mechanism 21, 23, 24; or 21 to 24 with connecting elements 6 to the supporting structure 15 or anchor rail 14 releasably connected.
