Grade 100 Chain Wll

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.

Grade 100 chain wll.

Alloy chain grade 80 or grade 100 should be used for overhead lifting. Users can experience more working power wll with a smaller diameter chain based upon application. Grade 100 is on average a 25 greater working load limit wll over grade 80. For basket slings and engineered lifts please consult as 3775 parts 1 or 2 accordingly.

Never use to lift people or items over people. This heavy duty lifting chain has a wll up to 8 800 lbs. When using fittings with chain you must match the trade size and meet or exceed the chain s grade. Maximum working load limit wll in tonnes assumes the use of a 100 rated shortening hook.

Failure to read understand and follow the cautions listed here may cause serious physical injury and property damage. Astm states that alloy chain shall be able to elongate a minimum of 20 before fracture 7 3 5. It s heat treated and stamped with the grade and manufacturer. This chain is approximately 25 stronger than grade 80 chain.

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. That number is the chain grade. Do not exceed working load limits wll. 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.

Proof tested to 200 of working load limit. Meets or exceeds all existing osha government nacm and astm specification requirements. Grade 100 chain slings. Grade 100 10 alloy chain slings.

Australian standard as 3775 2014. You could reverse this formula to determine ultimate breaking strength if all you know if the chain grade. Determining chain working load limits.
