Lifting accessories—such as clamps, lifting beams, C‑hooks, wire‑rope slings and lifting eyelets—are unequivocally within the scope of the Machinery Directive (MD) and the mirrored UK regulations (the Supply of Machinery (safety) Regulations 2008). They require conformity assessment, appropriate marking (CE in the EU or UKCA in Great Britain), a Declaration of Conformity (DoC) and a maintained Technical File.
Own‑use is not an exemption: if you design and put an accessory into service on your own site, you are the manufacturer in law and the full obligations apply. We at Knox Thomas see this misunderstood frequently in manufacturing environments, including during a recent engagement with a large diesel engine OEM.
1. Scope and Definitions
Under MD Article 1(1)(d) and Article 2(d), a lifting accessory is any component or equipment not attached to the lifting machinery that allows the load to be held—either placed between the machine’s load‑holding device and the load, or attached directly to the load.
Built‑in holding devices (e.g., an integrated hoist hook) are part of the lifting machinery and are not lifting accessories. Practical examples include clamps, beams and C‑hooks. Even components that do not resemble a traditional beam—such as disks with a welded lifting eye—are treated as lifting beams under EN 13155 when they perform the same load‑supporting function.
2. Own‑Use Obligations (CE/UKCA)
MD Article 4.1 requires that machinery may be put into service only if it satisfies the Directive. MD Article 2(i) and MD Guide §80 extend the definition of “manufacturer” to entities that design and build machinery for their own use; consequently, the same Essential Health and Safety Requirements (EHSRs), DoC and marking duties apply.
In the UK, the Supply of Machinery (Safety) Regulations 2008 implement the MD; UK guidance mirrors the MD provisions, so the technical compliance work (risk assessment, standards application, testing, marking, instructions and Technical File) maps across whether the marking route is CE (EU) or UKCA (GB). In short: own‑use machinery must be CE/UKCA compliant.
3. Applicable Standards
For the accessories most commonly encountered on production sites:
- EN 13155: safety requirements for grabs, C‑hooks and lifting beams. The standard establishes design verification criteria (strength, stability, securing/locking) and practical controls for tilt and load engagement.
- EN 13414: steel wire rope slings.
- EN 1677: sling components (e.g., hooks, links).
Apply the relevant standards to each accessory type and document the assessment in the Technical File.
4. Design and Verification Criteria (EN 13155 + MD Annex I Part 4)
Engineering verification must be evidence‑based and traceable:
- Strength margins (EN 13155): Mechanical load‑bearing parts shall withstand 3× WLL without releasing the load (permitted permanent deformation) and 2× WLL without permanent deformation.
- Static test MD (Annex I Part 4): Typically 1.5× WLL, unless the applicable standard specifies otherwise.
- Dynamic test: Typically ~1.1× WLL, set by risk assessment; EN 13155 does not mandate a single dynamic test regime.
5. Marking Requirements
Correct marking is integral to safety and traceability. For EN 13155 items, the plate shall include at minimum:
- CE (EU) or UKCA (GB) mark, as applicable;
- Manufacturer name and address;
- Designation/model;
- Unique serial number;
- Year of construction;
- WLL(s) for all configurations;
- Unloaded weight where relevant (if >50 kg or >5% of WLL);
- For C‑hooks/forks, the centre‑of‑gravity limits.
If the physical plate cannot accommodate required information, redesign the plate or the marking location—do not omit mandatory content.
6. Technical File Content
Regulators, clients and internal H&S teams will expect a complete Technical File to be produced on request. Maintain the following as a minimum:
- General description: intended use, GA drawings, labelling/plate location drawings.
- Detailed information: applied regulations/standards, bill of materials, part/assembly drawings, third‑party datasheets and Declarations, strength/stability calculations, warning‑label and nameplate drawings.
- Risk/EHSR assessment: risk register and mapping to product‑specific standards.
- References: standards list and identification of EHSRs covered by standards.
- Hazard mitigation: measures where standards do not fully apply; identification of residual risks.
- Inspection/test records: assessment and test reports, QC/commissioning procedures, functional/operational test procedures.
- Instructions: specifications/ratings, safety, installation/handling, commissioning, operation, setting, troubleshooting and maintenance (in the market language).
- Miscellaneous: the DoC and serial numbering description.
7. Family Approach and Serialisation
For efficient conformity management, group similar designs into families. MD Guide §383 allows a single EC DoC to cover a range of machinery produced in series, provided each unit can be identified as within scope (e.g., by a specific identification number) and the range is clearly specified.
Define the design envelope (e.g., spans, sections, lifting points, WLL ranges and attachments), hold it under configuration control, and serialise each unit to the family DoC and Technical File. This achieves efficiency without compromising traceability.
8. Implementation Roadmap
A structured compliance plan typically proceeds as follows:
- Define product families and scope. Catalogue all accessories in use; group by design principle and intended configurations. Establish the family envelope and allocate serial/ID conventions that link each unit to the family documentation set.
- Engineering verification. Complete calculations and checks against Annex I Part 4 and EN 13155 (or EN 13414/EN 1677 where applicable). Record the basis of design, load cases, factors, and results. Explicitly demonstrate the 3×/2× WLL strength criteria for load‑bearing parts for accessories within the scope of EN 13155.
- Testing. Plan and execute static and, where justified by risk, dynamic tests. Typical values (MD Annex I Part 4) are 1.5× WLL (static) and ~1.1× WLL (dynamic). Document procedures, instrumentation, acceptance criteria and outcomes.
- Marking and instructions. Apply CE/UKCA marking and full plate content; update instructions to reflect actual configurations and limits (including CoG constraints for C‑hooks).
- Documentation and declaration. Compile the Technical File contents listed in Annex B; issue the DoC referencing the MD (EU) or the UK regulations (GB) and the applied standards (EN 13155, EN 13414, EN 1677).
9. Non‑Negotiables
- A lifting accessory in service without marking, DoC, instructions and demonstrated engineering/test evidence is not compliant.
- Retrospective conformity is feasible only where compliance can be demonstrated through calculations, testing and documentation; otherwise the item must be upgraded or withdrawn.
- Own‑use equipment is not exempt; by putting it into service you assume the manufacturer’s duties in full. (Conclusion, p. 5.)

In short: we manage the technical work and documentation so that your equipment is demonstrably compliant and ready for service.
FAQ
1. Do lifting accessories need CE or UKCA marking?
Yes. Lifting accessories such as clamps, lifting beams, C-hooks, wire-rope slings and lifting eyelets need the correct product marking depending on where they are supplied. This means CE marking for the EU or UKCA marking for Great Britain. They also require conformity assessment, a Declaration of Conformity, and a maintained Technical File.
2. Is own-use lifting equipment exempt from CE or UKCA compliance?
No. Own-use is not an exemption. If you design and put a lifting accessory into service on your own site, you are the manufacturer in law and the full obligations apply. In short: own-use machinery must be CE/UKCA compliant.
3. What standard applies to lifting beams, clamps and C-hooks?
EN 13155 is the principal standard for grabs, C-hooks and lifting beams. It sets design verification criteria for strength, stability, securing and locking, along with practical controls for tilt and load engagement.
4. What happens if a lifting accessory has no marking or documentation?
A lifting accessory in service without marking, a Declaration of Conformity, instructions, and demonstrated engineering or test evidence is not compliant. Retrospective conformity is only feasible where compliance can be demonstrated through calculations, testing and documentation; otherwise the item must be upgraded or withdrawn.
