The scaffolding (1) for placing in or around a spherical unit, such as a tank (3), comprises a number of interconnected beams (5A,5B,5C,5D,5E), their connection being by releasable hinge arrangements at their outer ends (6). The beams form a ring-shaped construction fixed to the spherical object. The ring-shaped construction is rotatable around a vertical axis. The ring-shaped construction is displaceable with the aid of a cable (7) in a vertical direction from a first state resting in the spherical object to a second rotatable state in the spherical object. With the aid of wheels, it is rotatable around the spherical object. |
