Grade 70 Transport Chain

Grade 70 Transport Chain is a high quality, high strength carbon steel chain used for securing loads. It is not to be used for overhead lifting. All grade 70 transport chain must be embossed with 7, 70, or 700. Grade 70 chain may also be referred to as Binder Chain.


Chain Specification Definitions

Working Load Limit
The Working Load Limit (rated capacity) is the maximum load that shall be applied in direct tension to the undamaged straight length of chain.
Proof Test
The Proof Test (manufacturing test force) is a term designating the minimum tensile force which has been applied to the chain under a constantly increasing force in direct tenstion during the manufacturing process. These loads are manufacturing integrity test and shall not be used as criteria for service or design purposes.
Minimum Breaking Force
The Minimum Breaking Force is 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 a criterion for servuce or design purposes.
Overhead Lifting
That process of lifting that would elevate a freely suspended load to such a position that dropping the load would present a possibility of bodily injury or property damage.
Overload
Any static or dynamic load in excess of the Working Load Limit.
