摘要
This invention is a device for an overhead travelling crane (10) that is designed to move a long a beam (1) where the beam is designed to pass through a wall (4) or the like and one end of the travelling crane works with a wall component (5) whose shape is adapted to cover an opening in the wall that provides free passage for the travelling crane. The travelling crane works with an additional wall component (8). Each wall component (5 resp. 8) is detachably mounted on one side of the travelling crane (10) so that when the travelling crane passes through said opening (4a) it will cause the wall component in the opening to exit while the wall component that follows the travelling crane fills the opening.IMAGE
