Overview
SIST EN 1677-5:2001+A1:2009 sets out the safety requirements for forged steel lifting hooks with latch, Grade 4, designed for lifting slings. This European standard establishes specific criteria for the manufacture, testing, and marking of lifting hooks with a working load limit (WLL) up to 31.5 tonnes. These hooks are primarily used as components in:
- Chain slings compliant with EN 818-5
- Steel wire rope slings per prEN 13414-1
- Textile slings as defined in EN 1492-1 and EN 1492-2
The standard ensures that hooks used in lifting operations-whether for materials, objects, or goods-meet stringent safety and reliability expectations. It applies specifically to factory-forged hooks and not to hand-forged products.
Key Topics
- Design and Dimensions: Specifies requirements for the geometry and functional design of hooks, including eye formation and minimum/maximum dimension tolerances to ensure proper fit and safe loading.
- Material and Heat Treatment: Mandates the use of fully killed steel with particular chemical composition, and outlines appropriate heat treatment methods to enhance mechanical performance and durability.
- Mechanical Properties: Defines minimum thresholds for manufacturing proof force and breaking force (with safety factors) to guarantee operational reliability.
- Hook Latches: Requires each hook to have a robust, spring-loaded latch to prevent accidental release. Outlines performance testing for latches-including durability and resistance to force.
- Marking and Traceability: Hooks must be permanently marked with a code, grade number, manufacturer’s mark, and a unique traceability code for quality management.
- Testing and Quality Assurance: Details mandatory type tests, proof tests, and test regimes depending on whether the manufacturer is certified under EN ISO 9002.
- Documentation: Requires issuing a manufacturer's certificate of compliance and comprehensive retention of test and manufacturing records.
Applications
Forged steel lifting hooks covered under EN 1677-5 are essential safety components in:
- Heavy-duty Lifting Operations: Used in industries such as construction, logistics, shipping, steelworks, and manufacturing where safe material handling is critical.
- Assembly of Chain, Wire Rope, and Textile Slings: Ensures compatibility and safety when integrating hooks into sling assemblies for cranes and lifting devices.
- General Lifting Equipment: Any lifting system requiring reliable, high-strength hook components with positive latching for the prevention of accidental disengagement.
These hooks support the safe handling of heavy loads in compliance with machinery safety directives and national/international regulations.
Related Standards
Users of SIST EN 1677-5:2001+A1:2009 should also consider the following key standards for lifting equipment safety and component compatibility:
- EN 818-5: Chain slings made from short-link chain, safety requirements (Grade 4)
- EN 1492-1 and EN 1492-2: Textile slings with flat woven webbing or round slings made of man-made fibres
- prEN 13414-1: Steel wire rope slings, safety requirements
- EN 818-6: Information for use and maintenance of chain slings
- EN ISO 9002 / EN ISO 9001: Quality management systems for production and inspection
- EN 292 / EN 1050: Basic safety concepts and risk assessment principles for machinery
