Abstract

The ladder-platform combination (10), mounted on rollers (20), has at least two first beams (12) connected in pairs, with each pair being connected to a pair of second beams (14) relatively movable with respect to them. At least one pair of first beams is lockable to second pair in both directions by locking elements (e.g. 16a).
