Questions You Should Know about Load Lifting Chains Wholesale

     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. Whether you are an employee or an employer, feel free to contact Northern Strands about our various Safety Courses and our Below the Hook Rigging Seminars.

Whether you transport machinery, use tow chains, or are in the logging industry, it's important to know the working load limits of chain you are using. Chains have a working load limit- or WLL- of approximately one third of their break strengths (the amount of force the chains can withstand before they break).

How to Find the Working Load Limit

The chain grade and diameter determines the working load limit of the chain. Chain is embossed with both the grade and size so you can determine its WLL using this chart.

Types of chain

Grade 30 Chain

Grade 30 is a multipurpose, economical chain. Also known as Grade 30 Proof Coil Chain, people use this product in a variety of industries and jobs, including light construction, barrier chains, and in the marine industry. It is not safe for overhead lifting. Grade 30 chain is embossed using a 3, 30, or 300.

Grade 43 Chain

Also called Grade 43 High Test Chain or Grade 43 Tow Chain, this is common in the towing and logging industries. Never use this chain for overhead lifting. This chain includes designs embossed using a 43 or a G4.

Grade 70 Chain

Grade 70 Transport Chain, also called "Grade 70 Truckers Chain," works in securing loads for over-the-road hauling.Never use this chain for any overhead lifting. This chain include designs embossed using a 7, 70, or 700.

Grade 80 Chain

Grade 80 Alloy Chain works for overhead lifting due to its heat-treated design. People commonly use this type of chain as a heavy duty tow chain. Grade 80 chain include designs embossed using an 8, 80, or 800.

Grade 100 Chain

Considered premium quality chain, it offers about a 25% higher work load limit over Grade 80 chain. It is safe for overhead lifting. Grade 100 chains includes designs embossed with a 10 or 100.

Grade 120 Chain

A newer product in the market, Grade 120 chain is up to 50% stronger than Grade 80 chain and 20% stronger than Grade 100 chain. It's also more resistant to abrasion than both Grade 80 and Grade 100 chains. It's safe for overhead lifts.
