| Projekta Nr. | prEN 1991-3 |
|---|---|
| Nosaukums | (1) EN 1991-3 defines actions imposed by cranes and other machines including dynamic effects, if relevant, for the structural design of crane or machine supporting structures. (2) EN 1991-3 provides guidance on crane classification in terms of dynamic factors and fatigue actions. (3) EN 1991-3 applies to supporting structures of − bridge, gantry and wall cranes travelling on fixed runways; − fixed machines that cause a harmonic dynamic loading on fixed supporting structures. (4) The principles provided in EN 1991-3 can be applied also to determine actions on supporting structures of cranes other than those referred to in (3). (5) EN 1991-3 does not provide partial factors for actions. NOTE For partial factors for actions, see Annex A.5 to EN 1990:2023+prA1:2024. (6) EN 1991-3 does not provide actions or provisions for the design of cranes and machines. |
