What is the maximum percent of rated capacity that can be used to lift personnel?

In the context of lifting personnel, safety regulations dictate a maximum limit on the percentage of a crane's rated capacity that can be utilized. The correct answer of 50% is significant because it is established to ensure a safe lifting operation when personnel are involved. This limitation accounts for both the weight of the personnel and the dynamic forces encountered during lifting, such as wind, sudden movements, or shifts in load.

Using no more than half of the rated capacity helps to minimize the risk of tipping, mechanical failure, or other hazards that could arise if the crane were to operate near its full capacity, especially with human lives at stake. It is a crucial standard that promotes safety practices within the industry to protect workers during lifting operations. Understanding this threshold is essential for riggers and operators to maintain compliance with safety regulations and to keep personnel secure at all times while being lifted.
