<p>A group of objects (1-12) arranged in fixed relative positions on a floor (13) is moved while conserving said positions of the objects relative to each other by: providing a rigid framework (14) surrounding said group of objects and having supporting means for supporting each object as well as air cushion units (15); establishing supportive contact between each object and corresponding supporting means; lifting said framework as one rigid unit by activating said air cushion units; and displacing said framework.</p> |
