chain - Product Information
Our Grade 80 chain sling components and chain are manufactured to EN818-4 standard. The Working Load Limits (WLL) are rated by the Uniform Load Method of rating which is shown within the table within this section.
The WLL of a sling is dependant upon the diameter of the chain, the grade of the chain, the number of legs and the angle of the legs.
Chain Sling leg length is normally measured from the bearing point of the masterlink to the bearing point of the hooks, this is normally referred to as “b to b” or bearing point to baring point.
Grade 80 Chain Slings should generally be used within a temperature range of -40 to +200 degrees centigrade. They can be used at higher temperatures, but a reduction factor must be applied to the working Load Limit.
Due to the risks of embrittlement Grade 80 Chain Slings should not be used in acidic or caustic solutions or in heavily acidic or caustic laden atmospheres.
Grade 80 Chain Slings must not be heat treated, plated, coated or subjected to any process involving heating or pickling. Each of these processes can have dangerous effects and will invalidate the Sling manufacturers’ certificate.
Commercial short link and long link chain is manufactured from mild steel. It is normally galvanised but is also available as self colour. This type of chain should not be used for lifting of loads. Its applications include: mooring chains, area access restriction, agricultural, lanyard securing chains, etc.
