A Guide to Tested Chain

Lifting chains are a vital element in many different industries including hoisting equipment and material handling. They are typically made from alloy steel and the purpose of a tested lifting chain is to lift and move heavy loads safely and efficiently.

Whenever using lifting chains, it's essential to only ever use tested and certified chains and follow all procedures correctly to avoid any accidents or damage. Undoubtedly one of the most important aspects of lifting chains is their safe working load limit (WLL). This is the absolute maximum weight the chain can lift so always ensure the load is within the chains WLL. By following the correct procedures, certified lifting chains are reliable and safe equipment to lift heavy loads safely and efficiently.

How to measure a tested chain

There are a range of tested chain thickness sizes available including 7mm, 10mm and 13mm. Here are some top tips to remember when measuring:

• Use a calliper to measure the thickness of a tested chain accurately.
• Select a point where the chain isn't damaged or corroded as this could give an inaccurate reading. If any damage is noticed, don't use the chain and replace it.

It's important to measure the thickness as this will determine its WLL and ensure the correct chain is chosen for the job. Use the table to establish which WLL is relevant to the chain thickness.
