General Information

Overview
EN 1677-3:2001+A1:2008 is a CEN European safety standard for forged steel self‑locking lifting hooks – Grade 8. It defines design, material, dimensional, manufacturing and testing requirements for eye or clevis hooks with a working load limit (WLL) up to 21,2 t, primarily intended for use in:
- chain slings (EN 818-4)
- steel wire rope slings (prEN 13414-1)
- textile slings (EN 1492-1, EN 1492-2)
The standard focuses on preventing accidental load release, ensuring correct fit and durability, and provides informative annexes for hook dimension calculation (Annex A) and an example designation system (Annex B).
Key topics and technical requirements
- Design & locking: Hooks must incorporate a self‑locking mechanism that is activated by load and is replaceable. Lock hardness must be greater than the latch; locking must resist impact and not be opened by normal loading.
- Dimensions: Principal dimensions are tied to WLL (see Table 3 in the standard). Requirements include throat opening limits, point‑height minimums (point height ≥ 65% of throat opening), and seat diameter relations to ensure correct articulation and fit.
- Materials & heat treatment: Load‑bearing parts (including pins) must meet material and heat‑treatment criteria consistent with the EN 1677 family.
- Mechanical properties & workmanship: Tensile strength, hardness and workmanship rules are specified to avoid sharp edges and ensure durability.
- Type and manufacturing tests:
- Bend test (device and acceptance): after 40% WLL loading the hook must still be operable by hand; after WLL loading no cracking/fracture.
- Latch load tests (forces f1 and f2): minimum specified forces (3000 N or percentage of WLL) to verify latch strength and lateral resistance.
- Impact test on lock (pendulum method) and static tensile tests with locked hook position.
- Manufacturing test regime and acceptance criteria for production batches.
- Marking & documentation: Marking, manufacturer’s certificate and information for use are required to ensure traceability and correct selection.
Applications and users
- Who uses it: lifting gear manufacturers, sling and hook designers, quality and compliance engineers, safety inspectors, procurement specialists, and testing laboratories.
- Practical use: selecting compliant Grade 8 self‑locking hooks for chain, wire rope or textile slings; verifying supplier conformity; specifying hooks for lifting assemblies; preparing conformity documentation for CE/ Machinery Directive compliance.
