European foreword
This document (prEN 13001-3-1:2022) has been prepared by Technical Committee CEN/TC 147
“Cranes - Safety”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13001-3-1:2012+A2:2018.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
CEN/TC 147 WG 2 has reviewed EN 13001-3-1:2012+A2:2018 to adapt the document to technical
progress. The main changes are:
— Design values for bolt materials were changed (Table 5);
— Limit design values for welded connection were changed (5.2.5);
— Static proof of welded connections was changed (5.3.4 and Annex C);
— Proof of fatigue strength was revised to include additional modern methods (6.1);
— Fatigue strength specific resistance factors were modified (Table 9);
— The geometric stress (Hot Spot) method was added (6.2.4 and Annex I);
— The effective notch method was added (6.2.5);
— Lateral torsional stability of beams was added (8.4 and 8.5.3 and Annex J);
— Recommended tightening torques for preloaded bolts were modified (Annex B);
— Characteristic fatigue strengths for plates in shear were modified (Table D.1);
— Annex L with a list of hazards was inserted;
— Annex ZA was significantly revised.
This European Standard is one part of the EN 13001 series of standards. The other parts are:
— Part 1: General principles and requirements;
— Part 2: Load actions;
— Part 3-2: Limit states and proof of competence of wire ropes in reeving systems;

Introduction
This document has been prepared to be a harmonized standard to provide one means for the
mechanical design and theoretical verification of cranes to conform to the essential health and safety
requirements of the Machinery Directive, as amended.
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the scope of this document.
When provisions of this type-C standard are different from those which are stated in type-A
or B standards, the provisions of this type-C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type-C
standard.

1 Scope
This document specifies limit states, requirements and methods to prevent mechanical hazards in steel
structures of cranes by design and theoretical proof of competence.
The significant hazardous situations and hazardous events that could result in risks to persons during
intended use are identified in Annex L. Clauses 4 to 8 of this document provide requirements and
methods to reduce or eliminate these risks:
a) exceeding the limits of strength (yield, ultimate, fatigue);
b) exceeding temperature limits of material or components;
c) elastic instability of the crane or its parts (buckling, bulging).
This document is not applicable to cranes which are designed before the date of its publication as EN
and serves as reference base for the European Standards for particular crane types (see Annex K).
NOTE This document deals only with the limit state method in accordance with EN 13001-1:2015.

4.1 Documentation
The documentation of the proof of competence shall include:
— design assumptions including calculation models,
— applicable loads and load combinations,
— material grades and qualities,
— weld quality levels, in accordance with EN ISO 5817:2014,
— materials of connecting elements,
— relevant limit states,

---------------------- Page: 14 ----------------------
oSIST prEN 13001-3-1:2022
prEN 13001-3-1:2022 (E)
— results of the proof of competence calculation and tests when applicable.
4.2 Materials for structural members
4.2.1 Grades and qualities
For structural members, steels in accordance with the following European Standards shall be used:
a) Non-alloy structural steels EN 10025-2:2019;
b) Weldable fine grain structural steels in conditions:
1) normalized (N) EN 10025-3:2019;
2) thermomechanical (M) EN 10025-4:2019;
c) High yield strength structural steels in the quenched and tempered condition EN 10025-6:2019;
d) High yield strength steels for cold forming in conditions:
1) thermomechanical (M) EN 10149-2:2013;
2) normalized (N) EN 10149-3:2013.
e) Austenitic stainless steels EN 10088-2:2014.
Alternatively, grades and qualities other than those mentioned in the above standards and in Table 2
may be used, if the mechanical properties and the chemical composition are specified in a manner
corresponding to relevant European standard, and the following conditions are fulfilled:
— the design value of f is limited to f /1,05 for materials with f /f < 1,05;
y u u y
— the percentage elongation at fracture A ≥ 7 % on a gauge length Ls5,65× (where S is the
0
00
original cross-sectional area);
— the weldability or non-weldability of the material is specified and, if intended for welding,
weldability is demonstrated;
— if the material is intended for cold forming, the pertinent parameters are specified.
Where stainless steels are welded, special attention should be given to the welding process and
corrosion effects. Only austenitic stainless steels are covered by this standard.
Table 2 shows specific values for the nominal value of strength f , f For limit design stresses f see
u y. Rd
5.2. The values given are applicable for temperatures up to 100 °C for stainless steels and up to 150 °C
for all other steels. For more information see the specific European Standard.
To allow the use of nominal values of plate thicknesses in the proof calculations, the minus tolerance of
the plate shall be equal or better than that of class A of EN 10029:2010. Otherwise, the actual minimum
value of plate thickness shall be used. Nominal dimensions for other steel products than plates may be
used, provided those products comply with their standardized minus tolerances.
Where it is deemed necessary to check for internal defects, classes of EN 10160:1999 should be
specified.
