When attaching spreaders to a load, what is an important consideration?

When attaching spreaders to a load, it is crucial to understand the relationship between the spreader angle and the tension in the rigging system. When the spreader angle is lower, the tension in the slings or other rigging components increases. This is due to the mechanics of load distribution; a lower angle creates a greater vertical component of the force acting on the rigging, which translates to higher tension.

This concept is vital in ensuring that the rigging system can adequately support the weight being lifted and that it remains safe throughout the operation. A higher tension could lead to the risk of rigging failure or loss of load control. Hence, operators must consider this factor when selecting or adjusting spreaders for a particular load, as it directly impacts safety and operational effectiveness.
