Which angle in rigging systems may lead to an increase in load capacity?

In rigging systems, angles that approach vertical are crucial because they help to effectively distribute the load through the rigging equipment. When the angles are close to vertical, the tension in the rigging lines is optimized, minimizing lateral forces that can lead to instability or tipping. The vertical orientation ensures that the load is primarily transferred downwards, which aligns well with the gravitational forces acting on it.

As the angle moves away from the vertical, particularly towards horizontal, the load's effective capacity reduces due to increased tension in the rigging lines. A horizontal angle does not efficiently transfer weight and can lead to increased stress on the rigging setup. Angles less than 30 degrees often do not provide sufficient support for the load, and angles greater than 90 degrees can cause dangerous instability, risking the safety of the operation. Therefore, angles that are as close to vertical as possible are preferred to maximize load capacity and ensure safe rigging practices.
