Understanding Duplex Slings for Industrial Lifting
The choice of lifting equipment is crucial for ensuring safety and efficiency. One of the most versatile options available is the duplex sling. These slings are designed to carry heavy loads and are particularly useful in various lifting configurations. Selecting the correct type of sling and understanding their uses can significantly impact the success of your lifting operations.

Types of Lifts Using Duplex Slings
?
1. Straight Lift:??
? ?A straight lift is the most straightforward lifting method. In this configuration, the duplex sling is attached to the load without any additional rigging. This method is effective for lifting loads vertically and is typically used when the load's centre of gravity is well-defined. However, care must be taken to ensure that the load remains balanced throughout the lift.

2. Choke Hitch Lift:??
? ?The choke hitch lift offers more stability and control compared to a straight lift. In this method, the sling is wrapped around the load and then brought back on itself, creating a choking effect. This configuration is particularly useful for irregularly shaped loads, as it helps to secure the load and prevent it from shifting during the lift. It is essential to ensure that the sling is properly positioned to avoid slippage.

3. Basket Lift:??
? ?The basket lift configuration is ideal for lifting heavy or bulky items. In this method, the sling is looped back on itself, forming a basket shape that cradles the load. This design distributes the weight evenly across the sling, providing increased lifting capacity and stability. The basket lift is especially beneficial for loads that require additional support or for lifting items that are not conducive to other lifting methods.

Lifting Weights and Colour Codes
?
When selecting duplex slings, it's important to consider their lifting capacities and the colour coding that indicates their maximum load. Each colour corresponds to a different weight limit, which helps users quickly identify the appropriate sling for their lifting needs. Common colour codes include:
?
- Yellow: 1 tonne

- Blue: 2 tonnes
- Green: 3 tonnes
- Brown: 4 tonnes
- Red: 5 tonnes
- Purple: 6 tonnes
- Orange: 8 tonnes
- Grey: 10 tonnes
?
Always check the manufacturer's specifications for precise weight limits, as these can vary based on the construction and materials used in the sling.

Length Considerations
?
The length of the duplex sling is also a significant factor in ensuring successful lifts. Longer slings may be necessary for lifting from greater heights or for accommodating larger loads, while shorter slings can provide more control and stability. It's essential to assess the specific requirements of your lifting operation to determine the most appropriate sling length.
