Standard slings (chains, ropes, textile slings), which are covered under EN 818 and EN 1492, and fixed crane components like the hook block. Lifting attachments are rarely used for a single
One of the most critical technical aspects detailed within DIN EN 13155 is the categorization of stress and fatigue. Lifting attachments are rarely used for a single lift; they are subjected to thousands of cycles over their operational life. The standard provides detailed tables and formulas for "stress categories" and "mechanical stresses." It forces engineers to calculate the Working Load Limit (WLL) not just based on static weight, but on dynamic forces, impact factors, and the number of lifting cycles the device is expected to endure. By standardizing these calculations, the document ensures that a plate clamp rated for two tons in Germany performs with the same reliability and safety margin as one manufactured in France or Italy.
