Which statement best describes the risk of exceeding crane load charts with counterweights?

• A. Can increase structural loads to the point of collapse
• B. Increases speed of lifts
• C. Reduces total cost
• D. No impact on safety

Answer: (A)

Exceeding the crane load charts with counterweights threatens stability and structural integrity. Load charts specify the maximum safe lift weight for every combination of radius, boom length, and counterweight setup, reflecting how the crane and supporting structure (including outriggers) are designed to handle those forces. When you push beyond these limits, the loads placed on structural members, hoist gear, and hydraulics can exceed what they were engineered to bear, increasing the risk of component failure, tipping, or collapse. Dynamic factors during lifting—like acceleration, deceleration, and wind—make staying within the chart even more critical, since they can amplify effective loads. This risk is why the statement about exceeding load charts is the best description: it directly points to potential structural overload and collapse. It doesn’t describe lift speed, cost savings, or safety being unaffected, which are not accurate.
