There are several types of chain slings available, each designed for specific lifting applications and load requirements. The common types of chain slings include:
Single Leg Chain Sling: This type of chain sling consists of a single chain with attachments at both ends. It is suitable for vertical lifting of loads and is commonly used when a single point of attachment is sufficient. The attachments can be hooks, shackles, rings, or other suitable connectors.
Double Leg Chain Sling: A double leg chain sling comprises two individual chains connected to a master link or a fitting at the top. Each leg of the sling has its own attachment at the bottom, allowing for balanced lifting of loads. This type of chain sling is suitable for lifting loads that require stability and balance, such as long or wide loads.
Multi-Leg Chain Sling: Multi-leg chain slings consist of multiple chains, typically three or four, interconnected at a common point. They form a configuration resembling a triangle or a bridle. Each leg of the sling has its own attachment point, which provides stability and distributes the load evenly. Multi-leg chain slings are often used for lifting loads that require extra stability, such as cylindrical objects or loads with uneven weight distribution.
Adjustable Chain Sling: Adjustable chain slings feature a mechanism that allows the length of the sling to be adjusted according to the load requirements. This adjustability provides flexibility in lifting different sizes and shapes of loads. Adjustable chain slings are typically designed with additional fittings or hooks that enable the length to be easily modified while maintaining secure connections.
Endless Chain Sling: Endless chain slings, also known as grommet slings or endless loop slings, are formed by connecting the ends of a chain together to create a continuous loop. They do not have any specific attachment points and are versatile in lifting loads of various shapes and sizes. Endless chain slings are commonly used in applications where flexibility and multiple lifting points are required.
It's important to select the appropriate type of chain sling based on the load characteristics, lifting requirements, and safety considerations. Each type of chain sling has its own advantages and limitations, and consulting industry standards and regulations is crucial to ensure safe lifting operations.
