What is the maximum weight allowed for the combined loaded personnel platform and its rigging relative to the crane's rated capacity?

The maximum weight allowed for the combined loaded personnel platform and its rigging relative to the crane's rated capacity is set to ensure safe operation. OSHA and industry standards typically require that the weight of personnel platforms and their rigging should not exceed 50% of the crane's rated capacity. This requirement is in place to provide a significant margin of safety, considering the dynamic loads and potential impacts during lifting operations.

By limiting the combined weight to this percentage, it helps to prevent overloading the crane, which could lead to equipment failure, loss of control, or even catastrophic accidents. Additionally, this regulation accounts for various factors such as the stability and structural integrity of the crane while it is in operation, making sure that the risks associated with lifting personnel are minimized.

In contrast, the other options present higher percentages that would increase the risk of exceeding the crane’s rated capacity, potentially leading to dangerous scenarios.
