Chain and Components Specific

Chain and associated components can be subject to wear, twisting, misuse, overloading, intentional alteration, and corrosion. These and other usage variables may cause a reduction in working load limits. It is, therefore, important to regularly inspect all products to determine their safety prior to continuing their use.

Low and high carbon steel welded and weldless chain and accessories to be used in tension or pull applications are not to be used for lifting or hoisting purposes or when failure is likely to cause damage to property or persons. Jerking, shock loading or acceleration in the rate of application of a load multiplies the stress on the chain very rapidly and should be avoided. Actual applications should determine the size and grade of chain to be used.

Working Load Limits
This is the maximum load in pounds which should ever be applied to chain, even when the chain is new and when the load is uniformly applied in direct tension to a straight untwisted length of chain. The term “working load limit” contains no implication of what load the chain will withstand if any of the above factors are changed.
