Područje primjene nacrta:
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 1990-1:2023+A1:2026, 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 1990-1 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.
