When selecting the appropriate web sling for your needs, the primary consideration is the working load limit. Always ensure that the sling you choose remains within the manufacturer's specified capacity for the intended operation. Several key factors contribute to the sling's working load limit, including the number of plies, the width, and the lift configuration.
1. Web Sling Ply Count
Deciding on the ply count for your sling is crucial for optimal performance. Plies refer to the layers of polyester webbing stitched together to create a sturdier and more robust design. Naturally, the greater the number of plies, the stronger the sling will be. However, increased plies reduce flexibility, which might limit the sling's ability to fit into smaller lifting areas. Rigging professionals often keep one-ply slings handy because they are lightweight, easy to handle, and can easily navigate tight spaces.
2. Web Sling Width
The width of a sling significantly impacts its working load limit. A wider sling not only has a higher listed working load limit but also distributes the load more evenly across the webbing, providing better support. For protecting delicate machinery during lifting, wider slings are recommended as they maintain better contact throughout the lift, reducing the risk of damage.
3. Web Sling Configuration
The way you configure a sling during lifting can affect its working load limit, so it's essential to take this into account each time you use a web sling. Each THOR-TEX Polyester Web Sling comes with a certification tag attached near one end, detailing the working load limits for different configurations. This tag should always be consulted before setting up the sling for a lift.
NOTE: If the tag is ever removed, the sling should be retired, discarded, and replaced.
The eyes of a web sling play an important role in configuration. If you frequently use basket hitches for lifting, consider choosing a sling with line bearing points, as the eyes in this setup will bear most of the load and could experience more wear than choker or vertical hitches.

In conclusion, understanding these key factors—ply count, width, and configuration—is vital when choosing the right web sling. Proper selection ensures safe and efficient lifting operations, minimizing risks and maximizing the longevity of your equipment.
