prEN 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, 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.
