Sling Angles And Lifting Capacity
Effects Of Sling Angles
You must understand how sling angles affect lifting operations. Sling angles play a critical role in determining lifting capacity. When you use a basket hitch, the sling supports the load with two legs. A vertical angle provides maximum support.
As the angle between the sling legs and the horizontal decreases, tension increases, and the capacity to lift the load drops. In a choker hitch, the angle influences compression and friction. Lower angles increase stress on the sling and reduce the rated lifting capacity.
The following table shows how the sling angle impacts the capacity multiplier:
Sling Angle (degrees) | Capacity Multiplier |
|---|---|
60 | 1.73 |
45 | 1.41 |
30 | 1.00 |
You should always check the sling angle before lifting. Powerful Machinery’s product labeling and safety instructions help you identify the correct angle for each operation. You protect your team and equipment by following these guidelines.
Tip: Use the highest possible sling angle to maximize lifting capacity and reduce tension on the sling.
