Grade 100 Chain Wll

Zinc plated steel chain has good corrosion resistance.

Grade 100 chain wll.

Grade 100 lifting chain working load limits wll loading factors 10 75 1 31 73 1 41 2 25 4 0 63 0 5 0 4 0 8 1 1 0 9 0 63 0 8 1 4. Chain grades advertised by manufacturers are one tenth of the actual mathematical grades. Grade 80 grade 100 alloy chain single leg sling double leg sling triple quad leg sling size. Australian standard as 3775 2014.

It s heat treated and stamped with the grade and manufacturer. Grade 100 10 alloy chain slings. 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. This heavy duty lifting chain has a wll up to 8 800 lbs.

So grade 80 is really 800 and grade 120 is 1 200. Grade 100 is on average a 25 greater working load limit wll over grade 80. Never use to lift people or items over people. That number is the chain grade.

You could reverse this formula to determine ultimate breaking strength if all you know if the chain grade. For basket slings and engineered lifts please consult as 3775 parts 1 or 2 accordingly. Astm states that alloy chain shall be able to elongate a minimum of 20 before fracture 7 3 5. Grade 100 chain slings.

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. When using fittings with chain you must match the trade size and meet or exceed the chain s grade. Peerless 3 8 grade 100 alloy chain is quenched and tempered. Determining chain working load limits.

Alloy chain grade 80 or grade 100 should be used for overhead lifting. 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. Users can experience more working power wll with a smaller diameter chain based upon application. Do not exceed working load limits wll.

Failure to read understand and follow the cautions listed here may cause serious physical injury and property damage. Maximum working load limit wll in tonnes assumes the use of a 100 rated shortening hook. Meets or exceeds all existing osha government nacm and astm specification requirements. Proof tested to 200 of working load limit.
