Safety Notes

Do not use a chain in a manner that will exceed the WLL of the chain for the particular conditions of use. A risk assessment should be undertaken where chain is used in acidic, alkaline or other corrosive environments.

The strength of all grades of chain is adversely affected by excessively high and low temperatures. Where the temperature is likely to exceed 200°C or be used at temperatures colder than −10°C, the user should seek advice from the manufacturer.

Regular Inspections are essential

Using lifting gear can often have a high risk of injury, and the cost to business can be significant when something goes wrong.

It is important to ensure that regular examinations and inspections of lifting gear are undertaken to ensure maintenance is kept, and to verify that the equipment can continue to be safely used.
