What are the Types and Different Grades of Alloy Chain Sling?

Alloy steel chain slings are a popular choice for overhead lifting applications. These chain slings are among the hardest and most lasting lifting slings in the material handling sector. They are utilised for their strength, abrasion resistance, and ability to adapt to the contour of the loads. Also, alloy chain sling are ideal for more severe or harsh situations in the power, industrial, and petroleum sectors.

Types of Alloy Steel Chain Slings

As you would expect, alloy chain sling come in a variety of forms and sizes. Let’s look at some of them. 

Single-Leg Chain Sling

Single-leg chain slings typically feature a single chain length supporting the hoisted weight and a hook or collecting ring at the top end. They provide exceptional stability and balance when used in conjunction with other rigging equipment. They can also handle a variety of load sizes and are simple to use.

Double Leg Chain Sling

Double-leg chain slings, as the name indicates, feature two independent legs that are connected by a collector ring. Alloy steel chain slings are appropriate for lifting weights that require support at two corners, such as concrete slabs, skip bins, and large pipes.

Multi-Leg Chain Sling

These chain slings are used to carry weights of more than 180,000 pounds. Multi-Leg Chain Slings are made from three or more chains that allow you to employ various pickup locations for your cargo. This, in turn, helps to maintain balance and control. When utilising a chain sling with more than one leg, be sure that the load is uniformly distributed. Inspect all of the fittings and connecting devices that come with the sling.

Various Grades of Alloy Steel Chain Slings

You may have heard the words ‘Grade 80 chain sling’ or ‘carbon chain’ used without context. But what precisely does this mean?

The ‘grade’ of a chain indicates its strength or mean stress value. Chain grades for higher grades are tougher and more resistant to abrasion. Also, they have a higher strength-to-weight ratio and an elevated workload limit (WLL). 

The three types of alloy chain sling appropriate for lifting and rigging applications are:

Grade 80 Alloy Steel Chain slings

The Grade 80 standard for chain slings is widely used in overhead lifting, particularly in the towing and recovery sectors. It is also often utilized to secure huge cargo in the flatbed transportation business.

Most Grade 80 lifting slings are treated with a black armor protective treatment to increase their durability and service life. Furthermore, the alloy composition makes the chain lighter while maintaining its durability.

Grade 100 Alloy Steel Chain Slings

Grade 100 chain, like the Grade 80 chain, is designed to be strong. The heat-treated alloy steel used in Grade 100 is roughly 25% stronger than Grade 80 which makes it a superior choice for hoisting and overhead lifting applications. Also, grade 100 chains contain a tougher surface material and have high abrasion resistance.

Grade 120 Alloy Steel Chain Slings

Although seldom employed, Grade 120 chain slings are the indisputable champions of overhead lifting slings, distinguished by their square links. Grade 120 chains can also be identified by their blue, green, or brightly colored finish.

Also, grade 120 chains offer the highest strength-to-weight ratio among the three chain categories. This is because the square links used to make Grade 120 chains have a higher cross-sectional area per link.

The Bottom Line: 

Alloy steel chain slings are essential lifting equipment for many industries. Hopefully, this page has provided you with accurate information about their grades. With this information, you should have no issue buying the appropriate lifting chain slings for your next job.
