In a rigging block, as the included angle decreases, the load what?

• A. Decreases
• B. Remains Constant
• C. Increases
• D. Fluctuates

Answer: (C)

The main idea is that the way two rigging legs share the load depends on their angle. When the included angle between the legs becomes smaller, the load isn’t shared as effectively, so each leg has to pull harder to achieve the same lift. That higher effort in the legs translates to a greater load on the rigging hardware (slings, hooks, and fittings). So, as the angle tightens, the load on the rigging increases, which is why charts warn that narrow angles require higher-rated equipment.
