Abstract: A work stage includes a work platform having first and second sides and a cross-beam, a first support part supporting the work platform and a counter-support disposed at the first side. In addition, the work stage includes a first holder including a bolt and attaching the work platform to the first support part and enabling the work platform to rest against the counter-support. A first vertical strut is disposed essentially at a right angle to the cross-beam, a second holder is disposed on the second side and configured to hold the work platform, a tie rod is connected at one end to the second holder and at the other end to the vertical strut, and a second vertical strut is disposed parallel to and at a distance from the first vertical strut and configured to receive at least one transverse strut. The first vertical strut and the crossbeam are bearing mounted at the first holder so as to pivot simultaneously around the bolt.
