BS ISO 4347:2015

What is ISO 4347 - Leaf chains, clevises, and sheaves about?   

ISO 4347 is an International Standard that discusses leaf chains, clevises, and sheaves. 

ISO 4347 specifies the characteristics of chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachment ends of clevises. ISO 4347 provides you with dimensions, limits for interchangeability, length measurement, preloading, minimum tensile strengths, and minimum dynamic strengths. 

Who is ISO 4347 - Leaf chains, clevises, and sheaves for?  

ISO 4347 on leaf chains, clevises, and sheaves is useful for:  

• Heavy lifting equipment and machinery manufacturers  
• Manufacturers and suppliers of components for heavy lifting equipment and machinery 
• Product designers 
• Maintenance crews 
• Quality control personnel 

Why should you use ISO 4347 - Leaf chains, clevises, and sheaves?   

ISO 4347 guidelines help you with specifications for the components of slow-moving, low-frequency applications. ISO 4347 provides dimensions, limits for interchangeability, length measurement, and preloading for leaf chains, clevises, and sheaves.  

ISO 4347 also guides you with the minimum tensile strengths and minimum dynamic strengths for leaf chains, clevises, and sheaves. Details about performance requirements and markings have also been provided in ISO 4347. 

The components have low-maintenance features. This lengthens the period between servicing intervals while also reducing machine downtime.
