Umfang (scope):
1.1 Scope of EN 1991-3 (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 cranes, gantry cranes 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 EN 1990:2023, Clause A.5. (6) EN 1991-3 does not provide actions or provisions for the design of cranes and machines. 1.2 Assumptions (1) The general assumptions of EN 1990 apply. (2) The design of structures supporting cranes or machines is undertaken using information on actions provided by the manufacturer of the crane or machine.
