About
CHAIN TERMS
Grade of Chain: NACM (National Association of Chain Manufacturers & ASTM (American Society for Test Materials) classify chains in various grades. The higher the grade, the higher the working load limit for the same size of chain.
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 manufacturers 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.
Grade 70 chain was specifically designed for the transportation industry. Grade 70 Chain typically has a 20% higher working load limit than High Test Chain or Grade 43 Chain.
G70 chains are also referred to as Transport Chain, System 7, or Spectrum 7. Grade 70 Chain is NOT approved for overhead lifting.
G70 chains are also referred to as Transport Chain, System 7, or Spectrum 7. Grade 70 Chain is NOT approved for overhead lifting.
All of our Laclede Grade 70 Chain is Made in the USA. To help identify the grade and manufacturer all of our Grade 70 Chain is embossed withL7. The L is the chain manufacturer Laclede.
The 7 identifies this as a Grade 70 Chain. Grade 70 chain is typically finished with a Gold Chromate or Yellow Zinc.
You will also find a trace code embossed on the chain. This trace code provides Information about the manufacturing history of the chain as well as the origin of the steel.
The code is a combination of letters and/or numbers located on Grade 100, Grade 80, and Grade 70 chain.
These grades are all heat treated. (A process that involves heating chain to extreme temperatures to harden the material and improve the metallurgical and tensile properties of the chain).
Grade 70 is a high quality, high strength heat treated chain that is becoming the standard for load securement.
Grade 70 or Transport chain offers greater hardness and ultimate durability. Transport chain is primarily used and tow and binder chain in agriculture, construction, industrial, trucking and forestry.
All of our Grade 70 Chain is 100 percent Proof Tested. Certs available free of charge. Please request at the time of order placement.
