What does the load triangle indicate?

The load triangle is a crucial concept in rigging and hoisting as it visually represents the relationship between the load being lifted, the angles of the slings, and the tension experienced in each sling. When you're lifting a load with slings, the angle at which the slings are positioned directly affects the tension that each sling must bear.

Using the load triangle, you can accurately calculate the tension in the slings based on the angles. This is important to ensure that the equipment being used, including the slings themselves, is not overloaded beyond its capacity. By understanding the sling tensions indicated by the load triangle, riggers can make informed decisions about how to position slings and safely lift loads without exceeding the safe working limits of the equipment.

In summary, the load triangle serves as a visual and mathematical tool that helps riggers determine the necessary sling tension based on the angles at which the slings are applied, thereby ensuring optimal safety and efficiency in lifting operations.
