  • the working platform can be moved along the bars 80, 82, 84 in the transverse direction.
  • the displacement device may be a lever mechanism made of aluminum tubes.
  • This comprises a lever unit 62, which has a fastening unit 66 at one end.
  • the lever unit is pivotally mounted on the fixing unit 66, so that the lever unit 62 is pivotable in a vertical direction.
  • the stabilizing unit 64 includes two arms which are attached to a pivotable ring or tube, whereby the lever unit 62 is guided.
  • the guide rollers can be adjusted so that the distance between the individual work platforms with each other is not greater than a predetermined maximum dimension, for example, 5 cm.
  • a predetermined maximum dimension for example, 5 cm.
  • the attachment of an optional railing to the work platform 10 can also be carried out prior to mounting the work platform on the roof structure.
  • corrugated sheets may be removed from the roof cover first.
  • the work platform 10 can be lifted, for example, with a crane to the previously exposed location on the roof and placed on the roof structure. After the work platform completely rests on the roof structure, this can be solved for example by a hook of the crane rope.
  • the L-shaped safety bolts can be pivoted and tightened under a structure of the roof structure. In this way, the working platform 10 is protected from tipping and is now operational.
  • workers with personal safety equipment may be connected to a rope securing system attached to the work platform 10.
  • a system according to an embodiment of the invention is shown.
  • the system comprises a first work platform 10 and a second work platform 9, which are interconnected by means of an adapter module 90.
  • an end face of the adapter module 90 is connected to an end face of the first work platform 10.
  • bolts 96 for fastening the adapter module 90 are provided to the first platform 10 through holes.

  • bores 97 are likewise provided, through which a bolt for fastening the adapter module 90 to the second working platform 9 can be guided.
  • the adapter module is made of a rectangular frame which includes a first frame part 92 and a second frame part 94.
  • the first frame part 92 has a first end side of the adapter module 90 and the second frame part 94 has a second end side of the adapter module 90.
  • the two longitudinal sides of the second frame part 94 are displaceable within the longitudinal sides of the first frame part and can be fixed by means of a bolt 93, which can be guided through bores 95 of the frame parts.
