Flying constructions – a somewhat misleading construction term. What actually are flying constructions, and what is a construction book or inspection book? Temporary installations are subject, both inside and outside, to overall technical and legal requirements which may well differ at vital points. When it comes to open-air stages alone, standards of construction law, machinery guidelines and industrial-safety regulations set apparently contradictory provisions for the selection of materials. Why it is better for mobile constructions not to fly, and what must be noted when drawing up an inspection book and operating flying constructions, will be explained using numerous practical recommendations, with the aim of avoiding problems in a simple way.
