Lower angles (less than 45 degrees) increase stress on the rigging gear.

As the horizontal sling angle (the angle between the sling and the top of the load) decreases, the tension on the sling increases dramatically.
The configuration of the sling significantly alters its Working Load Limit (WLL). Types of Hitches Standard Crane Hand Signals (Aramco Standard)
The Rigger Level 3 Aramco Notes are divided into several sections, each covering a specific aspect of rigging and lifting operations. Some of the key sections include:
A load weighs 18,000 kg. You use a 2-leg bridle with an included angle of 90°. What is the tension in each leg?
Slings attached below the CG can cause the load to capsize or flip upside down during the lift. Always ensure the attachment points are above the Center of Gravity when lifting top-heavy structures. 6. Standard Crane Hand Signals (Aramco Standard)
