An operator observes a three-leg bridle sling tensioned with an angle of 30 degrees from the horizontal for each leg. If the total load is 9,000 kg, and it is known that the load could shift, what is the maximum potential theoretical tension on any single leg if two legs were to momentarily take the majority of the load due to an uneven lift?

Question: An operator observes a three-leg bridle sling tensioned with an angle of 30 degrees from the horizontal for each leg. If the total load is 9,000 kg, and it is known that the load could shift, what is the maximum potential theoretical tension on any single leg if two legs were to momentarily take the majority of the load due to an uneven lift?

Answer options:

• 3,000 kg (29.4 kN)
• 3,464 kg (34 kN) ✅ 5,196 kg (51 kN)
• 6,000 kg (58.8 kN)

Correct answer: 5,196 kg (51 kN)

Explanation: If two legs take the majority of the load, then Load / (2 * cos(angle)) = 9000 kg / (2 * cos(30°)) = 9000 kg / (2 * 0.866) = 9000 kg / 1.732 = 5196 kg. Provincial regulations and good practice emphasize considering load equalization issues. This calculation is vital for understanding practical rigging safety.
