The number of load changes is essential: The designer of a load handling attachment must determine in cooperation with the user whether DIN EN 13155 “Cranes – Safety – Loose load handling attachment” can be used or whether the load handling attachment must be designed in accordance with DIN EN 13001 and Eurocode 3 – DIN EN 1993 ” Design, construction and construction of steel structures”. If maximum load changes of up to 20,000 are to be expected for the load suspension devices to be designed, EN 13155 “Cranes – Safety – Loose load suspension devices” is applied in full. This means that the mechanical load-bearing parts are calculated in simplified terms in terms of mechanical strength, the strength against deformation must be >2 when new and the strength against fracture >3.
