For thousands of years, people have been using chain slings to hoist and move various weights and items. It is diverse and reliable. In fact, the chain sling is arguably one of the most common and robust forms of rigging available. Its popularity is the result of these properties and several others, including its longevity.
What Are Slings?
Simply put, a sling, composed of a high alloy steel, is the component that connects the load and the hoisting device or equipment. It has three major components:
- Master link
- A chain leg ( smaller links)
- Termination point or fitting e.g. hoist hook
This simplistic arrangement is also one reason why chain slings continue to be in popular use across a variety of industries.
What Are The Chain Sling’s Advantages?
In moving loads, a chain sling offers its users several advantages over other means. It is:
- Suitable for harsh environments – everything from foundries to steel mills
- Longevity – can last up to 40 years without requiring replacement
- Come in a variety of configuration setups
- More temperature tolerant than slings made from nylon or polyester
Governance of chain slings is under the jurisdiction and/or guidance of three specific groups:
- The National Association of Chain Manufacturers (NACM)
- The Occupational Safety and Health Administration (OSHA)
- The American Society for Testing and Materials (ASTM)
They ensure standards are set for the manufacture and use of chains slings.
The Versatile Chain Sling
Chain slings are a historical remnant of tool history. However, this piece of equipment remains popular and current today. The chain sling may be centuries old, but it is versatile and adaptive. As such, it has not remained a curiosity, but today continues to play an active role in moving heavy and awkward loads for various industries.
