Sling Angle Factor Chart: Understanding the Importance of Choker Hitches

When it comes to lifting and shifting heavy loads, the angle at which the sling is attached plays a crucial role in determining its capacity and safety. The choker hitch, in particular, requires careful consideration due to its unique characteristics. In this article, we will delve into the world of slings and explore the factors that affect their performance when used with a choker hitch.

The Choker Hitch: A Crucial Component

A choker hitch is a type of sling that wraps around or 'chokes' a load, providing a secure attachment point for lifting. This design allows for greater control over the load during transit and can increase stability and bearing capacity. However, it also poses some unique challenges.

Reduced Capacity and Safety Considerations

When using a choker hitch with an angle of less than 120 degrees, the sling body is more likely to fail at the point of choke when pulled to destruction. To mitigate this risk, the rated capacity must be reduced accordingly. This reduction in capacity can be significant, making it essential to carefully plan and execute lifts involving choker hitches.

Factors Affecting Capacity

Several factors influence the capacity of a choker hitch sling, including the angle at which it is attached, the diameter of the load, and the number of legs used. For instance, when using multiple legs or a spreader bar, the entire assembly must be balanced equally to ensure safe lifting.

The Importance of Proper Setup

Proper setup is critical for ensuring the safety and success of any lift involving a choker hitch sling. This includes ensuring that the 'choke' is tight and secure prior to lifting, as well as using a tagline to prevent load rotation. Additionally, slings must be carefully inspected and maintained before each use.

In conclusion, choker hitches are an essential component of the lifting process, but they require careful consideration due to their unique characteristics. By understanding the factors that affect their performance and following proper setup procedures, users can ensure safe and successful lifts. Remember, sling safety is paramount, and careful planning and execution are critical for avoiding accidents and injuries.
