There are a number of important factors to consider when using chain to lift a given obstacle. Shiny, gold, Grade 70 Transport chain is intended for load binding only. This chain is used to hold heavy items down to a flatbed truck and the gold-chromate finish as well as the carbon-steel construction makes this chain easy to spot and more difficult to break.
With this said, this chain should not be used for lifting unless it has been fabricated by a sling manufacturer and the manufacturer is required to follow guidelines for fabrication. ASME and/or ASTM standards must be followed and they require that either grade 80 or 100 chain be used in sling fabrication, due to the alloy steel construction and its ability to elongate when overloaded as opposed to snapping suddenly. The manufacturer will also have to put a tag on the chain sling that indicates what maximum load or Working Load Limit can be safely applied to the sling, making it easier for end users to know the limitations.
When lifting any objects off of the ground, the weight of said object as well as the capacities of the lifting device and rigging must all be known before making the lift. This important guideline is something that the Northern Strands' Training Division focus on in the Below the Hook Rigging training. Sections 208 and 209 of the Saskatchewan’s Occupational Health and Safety Regulations refer to this concept directly as well.
When in doubt about whether to lift a load with a certain chain or not ask yourself this question: Does the chain have a tag on it indicating its Working Load Limit?
If yes – there are a number of other questions you should ask yourself after this to determine that all of the parameters related to the lift are safe.
If no – do not attempt the lift and look for an alternative solution.
When performing any sort of lift whatsoever, it is important that workers are trained in safe rigging practices and that they are competently supervised.
