Overview
EN 1677-5:2001+A1:2008 is a CEN safety standard for forged steel lifting hooks with latch – Grade 4. It specifies design, material, manufacturing, testing and marking requirements for forged hooks with an eye and spring-loaded latch, rated up to 31.5 t WLL (working load limit). The standard is intended primarily for hooks used in chain slings (EN 818-5), steel wire rope slings (prEN 13414-1:1998) and textile slings (EN 1492-1 / EN 1492-2). Hand-forged hooks are excluded.
Key topics and technical requirements
- Scope and hazards: Identifies hazards addressed (clause 4) including accidental release, incorrect fit and handling risks; references risk assessment principles (EN 1050 / EN 292).
- Design & dimensions: Eye-type upper end to ensure articulation; dimensional relationships tied to WLL; key dimension rules include point height B ≥ throat opening O and O ≤ 95% of seat diameter D; latch must close over maximum bar diameter for the throat opening.
- Materials & heat treatment: Steel must be produced by electric or oxygen process, fully killed and stabilized against strain-age embrittlement; minimum aluminium content (≥ 0.025 %) required. Chemical limits: sulfur and phosphorus ≤ 0.025% (cast) / ≤ 0.03% (check analysis). Silicon: 0.12–0.30% (cast) / 0.15–0.35% (check).
- Manufacturing & workmanship: Requirements for forging, heat treatment and surface finish to avoid cutting/abrasion hazards.
- Mechanical properties & testing: Defines mechanical property requirements and tests - type tests, manufacturing proof tests (MPF), static tensile/breaking force (BF) tests and lot acceptance criteria.
- Hook latches: Spring-loaded latch requirements and torque guidance for latch testing.
- Traceability, marking & documentation: Marking, manufacturer’s certificate, designation system (Annex B) and instructions for use are required to ensure correct selection and safe use.
- Informative annexes: Annex A gives calculation bases for hook dimensions; Annex B gives an example designation system. Annexes ZA/ZB relate the standard to EU Machinery Directive requirements.
