Grade 100 alloy steel chain

未命名的设计-2

 

Grade 100 alloy steel chain / lifting chain:
Grade 100 chain was specifically designed for the rigorous requirements of overhead lifting applications. Grade 100 Chain is a Premium quality high strength alloy steel. Grade 100 Chain has a 20 percent increase in working load limit as compared to a similar size chain in Grade 80. This allows you to reduce the size of the chain depending on the working load needed. Grade 100 chains are also referred to as Grade 10, System 10, Spectrum 10. Grade 100 Chain IS approved for overhead lifting.
All of our Grade 100 chain is 100% subject to Proof Tested to twice the working load limit. The minimum break strength is four times the working load limit. Our Grade 100 Alloy Steel Chain meets all existing OSHA, Government, NACM and ASTM specification requirements.

Terms:
Working Load Limit (WLL): (rated capacity) Is the maximum working load that should be applied in direct tension to an undamaged straight length of chain.
Proof Test: (manufacturing test force) is a term designating the minimum tensile force which has been applied to a chain under a constantly increasing force in direct tension during the manufacturing process. These loads are manufacturing integrity tests and shall not be used as criteria for service or design purpose.
Minimum Breaking Force: 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. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer’s attribute acceptance test and SHALL NOT be used as criteria for service and design purpose.
Overhead Lifting: The process of lifting that would elevate a freely suspended load to such a position that dropping a load would present a possibility of bodily injury or Property damage.
