What percentage of the crane's weight can a single outrigger pad approach if not overloaded?

• A. 75% of the weight of the crane
• B. 85% of the weight of the crane
• C. 100% of the weight of the crane
• D. 110% of the weight of the crane

Answer: (B)

When considering the capabilities of the outrigger pads on a crane, it is important to understand their role in stabilizing the crane during operation. Outriggers are designed to distribute the load of the crane over a larger area to prevent tipping or overloading a single point on the ground. The correct understanding is that a single outrigger pad can safely approach 85% of the crane's weight without being overloaded. This percentage takes into account the necessary safety margins required during crane operation. It ensures that there is enough stability while minimizing the risk of ground pressure issues or potential tipping, which could occur if the outrigger were to bear too much weight. While the other percentages represent values that exceed safe operational limits, the 85% figure provides a balance between effective load distribution and maintaining safety. It reflects standard industry practices, which prioritize stability and safety, especially during lifting operations.
