prEN 1991-3

Eurocode 1 - Actions on structures - Part 3: Actions induced by cranes and machines

(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.

European foreword
This document (prEN 1991-3:2024) has been prepared by Technical Committee CEN/TC 250 “Structural
Eurocodes”, the secretariat of which is held by BSI. CEN/TC 250 is responsible for all Structural
Eurocodes and has been assigned responsibility for structural and geotechnical design matters by CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1991-3:2006.
The first generation of EN Eurocodes was published between 2002 and 2007. This document forms part
of the second generation of the Eurocodes, which have been prepared under Mandate M/515 issued to
CEN by the European Commission and the European Free Trade Association.
The Eurocodes have been drafted to be used in conjunction with relevant execution, material, product
and test standards, a
