How to Build the Perfect Chain Sling in 6 Simple Steps

Designing a lifting chain sling is more than selecting a chain and hooks. It requires accurate configuration, correct working load limit (WLL) calculations and a clear understanding of lifting angles, load distribution and operating conditions.

This guide shows how to build a compliant chain sling in 6 simple steps using the RUD Configurator, helping you improve safety, reduce errors and streamline your lifting design process.

The RUD Configurator is a free and straightforward chain sling calculator that helps engineers, riggers and lifting professionals design safer, more efficient slings with confidence. It helps save time on chain sling selection while improving application accuracy to create a safer lifting solution.

Step 1: Choose the Chain Type for Your Lifting Chain Sling

The first step in any lifting chain sling configuration is selecting the correct chain type based on your lifting application and required working load limit (WLL).

The options we have included are:

• Single-leg or multi-leg slings
• Single endless or double endless chains

Next, we need to determine the load capacity and choose between 2 grades:

• VIP Grade-100 - Strong and reliable, ideal for a wide range of lifting tasks across mining, construction and heavy engineering

• ICE Grade-120 - Offers higher strength, reduced weight and excellent performance in demanding environments, including low temperatures

Selecting the proper chain system ensures the sling delivers the required strength, durability and operational performance. Learn more about calculating Working Load Limits (WLL) for chain slings using ChatGPT (Opens a new browser tab with ChatGPT).

Step 2: Adjust for Operating Conditions

Correctly accounting for environmental conditions is critical for lifting safety and compliance with Australian rigging standards. Factors such as temperature, shock loads, and chemical exposure can affect WLL.

• VIP Grade-100 operates from -40°C to 200°C without WLL reduction

• ICE Grade-120 operates from -60°C to 200°C, making it ideal for harsh conditions

ICE components are recommended in challenging environments due to their wear-resistant materials. Choosing the right chain for your conditions ensures safety and longevity.

Step 3: Select Suspension Components

Suspension components are critical rigging equipment that connect the sling to the crane and the load. Options include master links, hooks, connecting elements, shortening elements and balancers. For guidance on selecting compatible components, see rigging hardware selection best practices using ChatGPT (Opens a new browser tab with ChatGPT).

The Configurator offers compatible suspension components based on your selections, helping ensure correct load distribution during crane lifting operations.

Step 4: Add Shortening Components

To balance loads or correct asymmetry, shortening components such as shortening hooks or shortening claws allow precise adjustment of sling length without compromising safety.

These components increase versatility and adaptability across different lifting scenarios. The Configurator highlights compatible options and shows how they integrate into the overall chain sling assembly.

Step 5: Add Intermediate Components

Intermediate components customise the sling for smooth operation and comply with Australian Standards (AS 3775.2).

• Swivel components prevent chain twists
• ICE tensioners allow precise length adjustment
• Proper articulation ensures axial load transmission

This step ensures the sling functions safely and effectively under real-world conditions.

Step 6: Select End Components

End components attach the sling directly to the load.

Common options include:

• Hooks
• Shackles
• End links
• Specialised lifting connectors

Selecting the correct end fittings is essential for secure load attachment and overall lifting system safety. The Configurator allows you to compare compatible options and confirm suitability.

Review the 3D Model and Export the Design

Throughout the process, you can visualise the sling in 3D. As components are added, the Configurator generates a realistic model, helping confirm the configuration before finalising the setup.

Once complete, users can:

• Download free finished chain sling CAD files and PDF documents for easy integration into engineering drawings, lift plans and project documentation
• Export PDF specifications for lift plans
• Share the configuration with colleagues or project teams
• Send the design directly to RUD for quoting or technical support

This integration ensures the chain sling design fits seamlessly into project planning and lift documentation.

Why Use a Chain Sling Calculator?

A chain sling calculator removes manual guesswork and improves accuracy in lifting load calculations. Instead of relying on charts or spreadsheets, users can configure a compliant sling based on real-world conditions. This makes it easier to standardise safe lifting practices across projects and teams.

Some of the key benefits are:

• Improved lifting safety and compliance
• Accurate working load limit (WLL) calculations
• Faster rigging design and selection
• Reduced risk of incorrect sling configuration
• Easy export of CAD drawings and lift documentation

Removing the Guesswork from Chain Sling Design

Designing a lifting chain sling no longer requires manual calculations or complex charts. The RUD Configurator is a free, easy-to-use chain sling calculator that helps you design accurate, compliant and safe lifting solutions.

By improving selection speed, application accuracy and safety, it enables engineers and rigging professionals to make confident decisions for every lift.

Selecting the proper chain is critical for safe lifting operations. Remove the guesswork of choosing the right chain length and components with the Australian RUD Sling Configurator, which helps you select the best RUD Grade-100 and Grade-120 chains for your requirements.

Configuring lifting chains does not have to be time-consuming or complicated. Traditionally, this involved multiple decisions such as selecting the chain grade, lifting angles, end components and load requirements. It also required manually cross-referencing charts, part numbers and technical specs.

But with the NEW RUD Sling Configurator, you can design, configure and create the proper chain sling for any lifting application. And in only six easy steps. So, whether you are an engineer wanting to do a lift plan, a rigging specialist or a lifting equipment supplier, the RUD online tool makes it faster and easier with a step-by-step process that ensures your final setup is safe and optimised for your specific lifting needs.
