This document has been prepared under a mandate 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, B, C or D, which is an integral part of this
document.
The main modifications concern:
 General requirement to introduce the reference to EN 13001-1 for the calculation;
 Vacuum lifters;
 Lifting magnet;
 Lifting beams for which the static load vary according to the working load.

Introduction
This European Standard 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 European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards are covered are indicated in the scope of this
standard.
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 European Standard specifies safety requirements for the following non-fixed load lifting attachments for
cranes, hoists and manually controlled load manipulating devices:
 plate clamps;
 vacuum lifters;
 self priming;
 non-self priming (pump, venturi, turbine);
 electric lifting magnets (battery fed and mains-fed);
 permanent lifting magnets;
 electro-permanent lifting magnets;
 lifting beams;
 C-hooks;
 lifting forks;
 clamps;
as defined in Clause 3.
This standard does not specify the additional 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;
 electrical hazards;
 hazards due to hydraulic and pneumatic components.
For high risk applications not covered by this standard, EN 13001-2 gives guidance to deal with them.
This standard covers the proof of static strength, the elastic stability and the proof of fatigue strength For
attachments designed for less than 16 000 lifting cycles, the proof of fatigue strength is covered by the proof
of static strength (elastic and yielded conditions, see 5.1.1.1)
This standard does not generally cover 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 standard does not cover slings, ladles, expanding mandrels, buckets, grabs, or grab buckets.

---------------------- Page: 8 ----------------------
oSIST prEN 13155:2014

The hazards covered by this European Standard are identified in clause 4.
This European Standard does not cover hazards related to the lifting of persons.
This standard is not applicable to non-fixed load lifting attachments for crane, hoists and manually controlled
load manipulating devices which are manufactured before the date this publication as EN
