What angle should your rigging be between the load and the crane?

Explanation:
The lift works best when the rigging forms a straight line from the crane hook to the load. When the line is straight, the lifting force acts vertically through the load’s center of gravity, with minimal horizontal or side forces. This keeps tension in the rigging at its lowest practical level and reduces the chance of sideways motion, sway, or instability during the lift. Any deviation from straight—like a right angle or a 45-degree angle—creates a horizontal component of force that increases required crane capacity, stresses hardware, and can make the load harder to control. In practice, aim for a straight connection and only accept deviations if obstacles force them, using appropriate rigging adjustments and safety considerations.
