Description
Working Load: The working load limit is the maximum load that shall be applied in direct tension to an undamaged straight length of chain.
Proof Load: The proof load test is the load at which the chain has been pulled in a direct tension on a straight length of chain, using a standart chain testing machine during manufacturing process.
Breaking Load: The minimum breaking load is the minimum force at which the chain, during manufacture, has been found by testing to break when a constantly increasing force is applied in direct tension.
Instructions and cautions regarding the use of chain:
Use only grade 80 (EN818–2) chain for overhead lifting applications.
Do not overload. Know working load limits and load weight of chain; overloading can lead to rapid wear, stretching and sling failure that may cause serious injury or property damage.
All attachments and accessories are designed for use with the appropriate size chain. Always make sure that the attachment is at least equal to the strength of the chain.
Inspect the chain before lifting to remove all twist, knots and kinks.
Avoid impact loading because loads that are jerked suddenly when picked up, can impose tension on the chain over the actuel load weight which may cause sling damage.
Do not let chains come in contact with sharp corners of load without protective loading which may result bending, nicks and gouges.
Do not add or weld any pieces to the chain other than factory’s standard.
Do not drop or rest loads on chain that will lead to nicking or bending that may result in severe chain damage.
Do not overheat the chain. Overheating may anneal the steel and may reduce the working load limits.
Proper chain care and extending the working life of chain;
Store chain properly to avoid damage such as nicking, gouging, bending and corrosion which may require repair or replacement.
Store chain away from heat.
If storing for long periods of time, oil the chain before storage.
Remove dirt and grit before storage as this can cause wear.
Inspecting the chain:
Always inspect the chain before and after using it.
Periodically measure the chain and keep records. Any chain inspected with deformation, elongation, nicks, gouges or breakes must be marked and immediately taken out of service.
Do not use hardly rusted chains for lifting purposes.
