In lifting and materials handling, the chain is often the unsung hero of the operation. Whether you are hoisting heavy machinery, securing loads for transport, or carrying out complex rigging work, the chain is the vital link that holds everything together. Choosing the correct lifting or load chain is not simply about finding something that fits; it’s about selecting a product that delivers safety, strength, and reliability in the specific conditions you work in.

At Bunzl Safety & Lifting, we understand that the wrong choice can result in downtime, compliance issues, or even accidents. This guide will explain the key factors including chain grade, breaking load, environment, and application so you can make an informed decision every time.

Before diving into the selection process, it’s important to clarify the distinction between lifting chains and load chains.

Lifting chains are specifically designed and tested to support and move loads vertically. They are manufactured to meet strict standards, such as Australian Standard AS 2321, and have defined working load limits (WLLs) for safe lifting.

Load chains (often referred to in securing applications) are used to restrain or anchor loads during transport or storage. While strong, they are not always rated for overhead lifting unless manufactured to the correct specification.

Using the correct chain type is essential and load chains must never be used in place of lifting chains, unless explicitly certified for the task.

Selecting the Right Chain Grade

The grade of chain refers to its material composition and manufacturing standard, which in turn dictates its strength and performance.

Grade 80 (G80): The industry standard for most lifting applications. G80 (T) Lifting chains are made from high-strength heat treated alloy steel, offering an excellent balance of strength, durability, and affordability. They are ideal for heavy duty lifting applications.

Grade 100 (G100): Around 25% stronger than G80 chains, G100 chains allow you to lift the same load with a lighter chain or lift heavier loads with the same chain size. They are ideal for high-intensity industrial lifting operations where efficiency and reduced weight matter.

Grade 120 (G120): The highest grade available in some markets, offering even higher strength-to-weight ratios. These chains are often used in the most demanding environments, such as offshore lifting or extreme heavy industry.

Choosing the correct grade will depend on load weight, frequency of use, and the need for weight reduction in your lifting gear. Bunzl Safety & Lifting offers a range of chain grades to suit everything from standard workshop lifting to high-performance industrial tasks.

Considering Breaking Load and WLL

When selecting any lifting or load chain, understanding the difference between breaking load and WLL is vital.

Breaking load is the maximum force the chain can withstand before it physically fails. This is a test value and should never be approached in operational use.

WLL is the maximum safe load the chain is designed to carry during normal operations. This is typically a fraction of the breaking load, incorporating a safety factor (often 4:1) for lifting equipment.

To determine the WLL you need, you must calculate the maximum weight of your loads, factoring in the configuration of the lift (e.g. sling angles, multiple-leg assemblies) and potential dynamic forces.
