If you cannot find the original DIN 15058, an equivalent summary of its brake calculation methods is available in the textbook “Crane Design: Theory and Practice” (Verschoof, 2002), which references the DIN 15000 series extensively. Need help interpreting an old brake specification? Consult a certified crane safety engineer – working from withdrawn standards without modern context can be hazardous.

What is DIN 15058? DIN 15058 is a now-withdrawn German industrial standard titled "Cranes; Brakes; Mechanical Design, Calculation, and Testing." It was part of the renowned DIN 15000 series of crane standards, which formed the backbone of crane design and safety in Germany and many other countries for decades.
