Determining chain working load limits.
Grade 80 grade 100 alloy chain single leg sling double leg sling triple quad leg sling size.
Grade 100 10 alloy chain slings.
Zinc plated steel chain has good corrosion resistance.
All grade 100 chain and fittings meet and exceed australian standards all chain slings supplied by ranger are nata proof tested and tagged.
When using fittings with chain you must match the trade size and meet or exceed the chain s grade.
Proof tested to 200 of working load limit.
Astm states that alloy chain shall be able to elongate a minimum of 20 before fracture 7 3 5.
You could reverse this formula to determine ultimate breaking strength if all you know if the chain grade.
To ensure that alloy chain consistently meets this requirement astm requires the use of certain alloying elements in the manufacturing of the steel for alloy steel chain.
This chain is approximately 25 stronger than grade 80 chain.
Never use to lift people or items over people.

Meets or exceeds all existing osha government nacm and astm specification requirements.
This heavy duty lifting chain has a wll up to 8 800 lbs.
Do not exceed working load limits wll.
Chain grades advertised by manufacturers are one tenth of the actual mathematical grades.
Failure to read understand and follow the cautions listed here may cause serious physical injury and property damage.
Grade 100 chain is quickly becoming the more popular choice for construction manufacturing and rigging companies grade 100 chains is approved for overhead lifting applications.
Australian standard as 3775 2014.
Grade 100 is on average a 25 greater working load limit wll over grade 80.
Resources working load limit guides grade 100 chain sling wll guide.
So grade 80 is really 800 and grade 120 is 1 200.
Users can experience more working power wll with a smaller diameter chain based upon application.
Peerless 3 8 grade 100 alloy chain is quenched and tempered.
Grade 100 chain is 25 stronger than grade 80 chain allowing for easier handling and increased efficiency due to its higher alloy content grade 100 chain is also more rugged and resistant to fatigue.
Alloy chain grade 80 or grade 100 should be used for overhead lifting.
