What is BS EN 1677-5 - Forged steel lifting hooks with latch - Grade 4 about?
Sling is an assembly consisting of chain, wire rope or textile joined to upper and lower terminals suitable for attaching loads to the hook of a crane or other lifting machines.
BS EN 1677 is a European Standard on components for slings. The main aim of the BS EN 1677 series is to offer component safety linkages and verify hook design to ensure its suitability for the intended application.
BS EN 1677-5 is the fifth part of the series that specifies requirements for forged steel lifting hooks of grade 4 having latch and eye up to 31,5 t WLL, mainly for use in:
- Chain slings according to EN 818-5
- Steel wire rope slings according to prEN 13414-1:1998
- Textile slings according to EN 1492-1, EN 1492-2
intended for lifting objects, materials or goods.
The hazards covered by BS EN 1677-5 are identified in clause 4.
Annex A gives the bases for calculation of hook dimensions.
Annex B gives an example of a designation system for hooks of grade 4.
Note: BS EN 1677-5 does not apply to hand-forged hooks.
Who is BS EN 1677-5 - Forged steel lifting hooks with latch - Grade 4 for?
BS EN 1677-5 on forged steel lifting hooks with latch - Grade 4 is useful for:
- Manufacturers of sling components
- Manufacturers of accessories used for lifting equipment
- Manufacturers and suppliers of steel
- Designers of lifting hooks and hook hatches
- Quality testing personnel
Why should you use BS EN 1677-5 - Forged steel lifting hooks with latch - Grade 4?
A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or a crane. A lifting hook is usually equipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached.
In this regard, BS EN 1677-5 provides the significant safety or health hazards, safety requirements, design, dimensions, materials and heat treatment and mechanical properties of the product.
BS EN 1677-5 covers the verification of safety requirements and hook hatches and includes marking and manufacturer’s certificate for steel lifting hooks with latch - Grade 4.
As a result, if you are a manufacturer of sling components, complying with BS EN 1677-6 can demonstrate the quality, performance, and dependability of your products, achieving the strength and can withstand high weighting. Ultimately, latches may help ensure a sling is properly secured to the load and prevent the load from sliding when the sling is slack.
