Applicable to steel structures of railless cranes on vehicles with stress collectives equal to or lighter than S1, a limiting stress ratio x not less than -0,25 and notch cases equal to or better than K3 in accordance with DASt-Richtlinie (DASt Guideline) 011. Incorporates deviations from, and additions to, DIN 15018 Part 1 which are motivated by the specific system characteristics, requirements and by the special mode of operation of these cranes. Cranes on vehicles are equipped with jib systems, basic jibs which may also be fitted with a fixed jib extension or with a level luffing jib extension, which are capable of being lowered rapidly, and the basic jobs of which are luffable about a horizontal axis.
