European foreword
!This document (EN 13155:2020+A1:2025) has been prepared by Technical Committee CEN/TC 147
“Cranes - Safety”, the secretariat of which is held by SFS.
This document supersedes EN 13155:2020.
The main modifications between EN 13155:2020 and EN 13155:2020+A1:2025 concern:
— there are two distinct verification methods, by calculation and test or by test only. The errors
associated with each of these verification methods have been rectified;
— the verification by test only requires testing to the elastic condition, 2 × WLL without permanent
deformation and yielded condition, 3 × WLL without releasing the load;
— the verification by calculation makes allowance for lower working coefficients for certain technically
justified cases;
— load testing using a scaled load factor dependent on working load limit has been included to verify
calculated mechanical strength.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document."
The main modifications between EN 13155:2003+A2:2009 and EN 13155:2020 concern:
— general requirement to introduce the reference to EN 13001-1 and −2 for the calculation;
— vacuum lifters;
— lifting magnet;
— the addition to the scope of lifting insert systems for lifting prefabricated concrete products;
— reduction of load changes from 20 000 to 16 000 in all clauses.
!Any feedback and questions on this document should be directed to the users’ national standards
body. A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United

Introduction
!This document has been prepared to be a harmonized standard to provide one means for non-fixed
load lifting attachments used on cranes to conform with 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 at the drafting
process of this document.
The machinery concerned and the extent to which hazards 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 non-fixed load lifting attachments which have been designed and built according to the
provisions of this type C standard."

1 Scope
This document specifies safety requirements for the following non-fixed load lifting attachments for
cranes, hoists and manually controlled load manipulating devices:
a) plate clamps;
b) vacuum lifters:
1) self-priming;
2) non-self-priming (pump, venturi, turbine);
c) lifting magnets:
1) electric lifting magnets (battery fed and mains-fed);
2) permanent lifting magnets;
3) electro-permanent lifting magnets;
d) lifting beams;
e) C-hooks;
f) lifting forks;
g) clamps;
h) lifting insert systems for use in normal weight concrete,
as defined in Clause 3.
This document does not give requirements for:
— non-fixed load lifting attachments in direct contact with foodstuffs or pharmaceuticals requiring a
high level of cleanliness for hygiene reasons;
— hazards resulting from handling specific hazardous materials (e.g. explosives, hot molten masses,
radiating materials);
— hazards caused by operation in an explosive atmosphere;
— hazards caused by noise;
— hazards relating to the lifting of persons;
— electrical hazards;
— hazards due to hydraulic and pneumatic components.
For high risk applications not covered by this standard, !EN 13001-2:2021", 4.3.2 gives guidance to
deal with them.
This document covers the proof of static strength, the elastic stability and the proof of fatigue strength.
This document does not generally applies to attachments intended to lift above people. Some attachments
are suitable for that purpose if equipped with additional safety features. In such cases the additional
safety features are specified in the specific requirements.
This document does not cover slings, ladles, expanding mandrels, buckets, grabs, or grab buckets. This
document does not cover power operated container handling spreaders, which are in the scope of
EN 15056.
This document is not applicable to non-fixed load attachments manufactured before the date of its
publication.
