What To Consider Before Buying Lifting Chain Slings?

lifting-chain-slings

Lifting chains and slings are used in the construction, mining and materials handling industries to lift heavy objects. Lifting chains are made of steel or nylon and are designed for specific lifting tasks. Slings are made of nylon or polyester. A lifting chain is a series of links connected by pins or shackles that can be attached to a hook with a load-bearing capacity of up to 5 tons. Lifting chains are available in various lengths, diameters and strengths.

There are several factors to consider when selecting lifting chain slings. The chain must be strong enough to support the load, and it must be able to withstand the forces of the load. It is also important for a chain sling to be able to withstand its environment; if you are using your chain sling outside, for example, it’s important that your chain sling has been properly galvanized and coated with a protective finish.

Grade 80 or Grade 100 chain for lifting?

If you need to lift something that weighs over 10 tonnes, then you’ll want to look into using the Grade 80 chain. Grade 100 chains are stronger than grades 50 and 80, but they’re also more expensive, stiffer and heavier. If your project requires flexibility rather than strength, then grade 100 may not be the best choice for you and if the price is an issue, you’ll obviously want to avoid it altogether.

Sling Leg Length

You should make sure that the leg length of your sling is at least equal to its capacity. For example, a 4,000 lb capacity sling should be used with legs that are at least 4 inches in length. If you use a leg length shorter than this, it may not be able to support your load. If you have a larger capacity sling and use short legs, it could cause the material to fail and collapse under load.

Sling Headroom

Headroom is the distance between the sling and the load. Headroom is important because it prevents loads from hitting slings during lifting, which can lead to damage to both equipment and personnel. The amount of headroom varies depending on the type of rigging system being used, but most commonly, it is specified in inches on drawings that are issued with lifting chain slings.

The gauge

The size of the chain links is a primary factor in determining how much weight your sling will be able to lift. It is also related to the weight of each link itself, which can be found by multiplying the length and width together. In general, chains with larger gauge numbers are stronger than those with smaller gauges.

Finish 

  • Rustproofing – The process of adding a protective layer to the surface of the metal.
  • Galvanized – A popular coating for lifting chain slings, galvanizing is a method of electroplating zinc on the surface of steel or iron.
  • Zinc plating- A thin layer of zinc is applied to the chain sling using an electroplating process.

End Fittings

Here are some common end fittings:

  • Slip hooks are used for lifting heavy loads. They have a hole in them and a pin on the opposite side that locks when you pull it through.
  • Grab hooks are used for lifting light loads, loads that aren’t round (pipe, flat steel), or sharp edges/corners (lumber).

When you head over to the lifting chain slings suppliers, be sure to keep these factors in mind and then proceed with the purchase.
