Overview

EN 13155:2020/FprA1 (CEN) specifies safety requirements for non-fixed load lifting attachments used with cranes, hoists and manually‑controlled load‑manipulating devices. Covered attachment types include plate clamps, vacuum lifters (self‑priming and non‑self‑priming), lifting magnets (battery, mains, permanent, electro‑permanent), lifting beams, C‑hooks, lifting forks, clamps, and lifting insert systems for normal‑weight concrete. The amendment updates references (notably EN 13001‑2:2021) and introduces clarified verification methods.

This standard excludes: direct contact food/pharmaceutical uses requiring special hygiene, handling of specific hazardous materials (explosives, molten metal, radioactive), explosive atmospheres, noise hazards, lifting persons, electrical hazards, and hydraulic/pneumatic hazards. It also does not apply to certain items (slings, ladles, buckets, grab buckets) or to attachments manufactured before publication.

Key topics and requirements

• Design strength and verification
  • Covers proof of static strength, elastic stability and fatigue strength.
  • Two verification routes: verification by calculation and verification by test only. The amendment corrects errors in both methods and adds a variable test regime supporting calculated results.
  • Test-only requirements: elastic condition at 2 × WLL (no permanent deformation) and yielded condition at 3 × WLL (without releasing the load).
  • Calculation route: mechanical parts must withstand 2 × WLL; in technically justified cases lower coefficients down to 1.65 may be used with proper justification.
• Fatigue and limit states
  • Fatigue proof references EN 13001 series (EN 13001‑1, EN 13001‑2:2021, EN 13001‑3‑1, etc.) where applicable.
• Operational characteristics
  • Default allowance for unintended tilt angle ±6° (can be reduced if justified).
  • Requirements for securing moving parts (e.g., lifting beams) and minimum performance levels for monitoring devices (EN ISO 13849‑1:2015, Performance Level c, Category 3).
• Manufacturing and conformity
  • Series production may use sample testing supported by documented quality systems (e.g., EN ISO 9001) to satisfy individual verification.
  • Information for use must include working load limit (WLL) and applicable markings; the amendment prefers the term conformity marking over CE in some clauses.

Applications and who uses it

• Manufacturers of non‑fixed lifting attachments (design, verification, technical documentation)
• Crane designers and integrators selecting compatible lifting accessories
• Safety engineers and inspection bodies validating strength, fatigue and stability
• Procurement and asset managers specifying WLL and conformity requirements
• Certification bodies and notified bodies applying EN 13155 in CE/conformity assessments

Related standards

• EN 13001 series (General crane design and load actions) - updated reference: EN 13001‑2:2021
• EN ISO 13854:2019 (minimum gaps to avoid crushing)
• EN ISO 13849‑1:2015 (safety‑related control systems)
• Component standards cited for ropes, chains and fittings (EN 818, EN 1492, EN 1677, EN 13414, EN 13889, EN ISO 3266, etc.)
• EN 15056 (power‑operated container handling spreaders - excluded)

This standard is essential when specifying, designing or certifying safe, compliant non‑fixed lifting attachments and ensures reliable integration with crane systems while highlighting verification and documentation best practices.

European foreword
This document (EN 13155:2020/prA1:2023) 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 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) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annexe ZA, which is an integral
part of EN 13155:2020.
The main modifications compared to EN 13155:2020 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. The calculated results are supported by testing using a variable sliding scale
of test loads for verification of the calculated mechanical strength has been included.

5 Modifications to Clause 5, "Safety requirements and/or protective measures"
In 5.1.2.1, replace the text of the subclause with:
"The coefficients mentioned below cover the uncertainties of the value of the actual load and the impact
factor for hoisting a grounded load (dynamic effect) in general applications. The proof of fatigue strength
is not necessary, it is covered by the global safety of the proof of static strength.
— Verification by calculation.
The mechanical load bearing parts shall be designed to withstand a static load of two times the
working load limit without permanent deformation.
If technically justified this factor can be reduced further but not less than 1.65. A technical
justification would be accurate estimation of a lower dynamic factor imposed by the specific rigging
and lifting machinery being used.
NOTE The factor two above covers all cases of any combinations of partial safety factor (γ ), dynamic factor
p
and resistance factor (γ ) (see EN 13001 series).
m
— Verification by test only
The mechanical load bearing parts shall be designed to withstand a static load of two times the
working load limit without permanent deformation.
The mechanical load bearing parts shall be designed to withstand a static load of three times the
working load limit without releasing the load even if permanent deformation occurs.".
In 5.1.2.2, replace all text in the subclause with the following:
"The proof of the static strength regarding elastic and yielded condition shall meet 5.1.2.1. Fatigue
strength shall be proved in accordance with the methods stated in EN 13001-1:2015, EN 13001-2:2021
and EN 13001-3-1:2012+A2:2018. Consideration to other parts of the EN 13001 series that would be
applicable to the specific device shall be included, for example EN 13001-3-5:2016+A1:2021, Cranes -
General design - Part 3-5: Limit states and proof of competence of forged and cast hooks.".
In 5.1.2.3, replace all text in the subclause with the following:
“Load lifting attachments should be designed for an unintended tilt angle of ±6 degrees deviation from
the maximum working angle.
SIST EN 13155:2021/oprA1:2023
EN 13155:2020/prA1:2023 (E)
If technically justified an unintended tilt angle less than 6 degrees can be used.“.

In 5.1.5, replace the list of standards with the following:
"
— EN 818-4:1996+A1:2008;
— EN 818-5:1999+A1:2008;

In 5.1.7, replace the reference to EN ISO 5817 with "EN ISO 5817:2014".
In 5.2.3.4.3, replace the reference to EN 349 with “EN ISO 13854:2019” to read:
“The control for operating the magnet in accordance with EN 13854:2019 with regard to the place for the
operator’s hands.“.
In 5.2.3.5.2 replace the second paragraph with:
“The monitoring device shall comply with a minimum performance level c, control category 3 of EN ISO
13849-1:2015.”.
In 5.2.5.3 add the following paragraph and NOTE after the second indent: “
Where whole load containment is needed by a secondary means, the correct system should be selected,
e.g. using a brick box, cage or full containment for an unsecure pallet of blocks. A crane fork with load-
resistant net should not be selected, as this is not a suitable or safe method of lifting.
NOTE A load-resistant net is not designed to contain a whole load. Also, any damage to the net significantly
reduces its load carrying capacity.“.
