Chain Slings are among the strongest and durable types of rigging for a wide variety of applications. It isn’t uncommon to look at chain slings that have actually been in service more than 40 years ago. The original chain sling was developed for the purpose of raising heavy loads (over 100 tons) with the use of rope and chain. While these heavy-duty chains still work well for many applications, there have certainly been considerable developments in the design and capabilities of modern chain slings.
Many modern chain slings utilize fibres or polyester filaments woven onto a high tensile rope. These fibres provide excellent abrasion resistance, wear resistance, and tensile strength. However, some rope fibres are much stronger than others, and so weaker abrasion and fatigue resistance are needed. The strength of the fibres should be determined by the type of load, the distance between the chain and the anchor point, and the chain pattern.
The types and features of chain sling –
The strength of a wire rope sling will depend upon the diameter of the chain and the weight being lifted. Additionally, the length of the wire rope may determine how much chain can be lifted. Longer chains tend to use less chain to lift the same weight. Most modern chain slings also incorporate anti-friction tape on both the ends of the rope for additional strength.
Another type of chain sling is the uv lifting sling, which is more versatile and lighter than its traditional metal retracting sling. UV slings allow the chain to be stored away during warm days or other times when the sun isn’t out. The lightweight nature of a uv-lifting sling makes it easy to transport the equipment. This type of chain sling is also more resistant to abrasion and fatigue than a comparable metal retracting sling. It is designed with a U-shaped webbing for maximum security and stability.
Grab hooks are popular among anyone who works in construction or other industries that require long spans of ladders and scaffolding. A chain grab hook is used as a single unit, with one end attached to a connecting wire rope. The other end of the grab hook is attached to an anchor point on the tower, which allows the person to use the rope for a longer period of time. Chain grab hooks are commonly used for long-run construction projects such as on tall buildings or cranes. Chain grab hooks are often used in conjunction with leg chain slings to provide a safer, more convenient way of lifting heavy loads.
There are many different chain sling designs available for different applications. Some slings are powered by foot power or chain energy, which allows them to be run along or over almost any surface. Others are powered by electric motors, which make them easier to operate and move around. The design factor of a chain sling is its flexibility and ease of use, allowing it to be used in many different applications.
