Why is it important not to exceed 50% of rated capacity when lifting personnel?

In the context of lifting personnel with cranes, it is crucial to adhere to a safe lifting capacity to ensure safety and prevent accidents. Exceeding 50% of the rated capacity significantly increases the risk of failure in the equipment or instability while lifting, which could result in serious injury or fatality to personnel. The rated capacity of a crane includes safety margins that are designed to protect against unforeseen circumstances, such as dynamic loads and improper positioning.

By limiting personnel lifts to 50% of the rated capacity, operators maintain a significant safety buffer that accounts for variables such as wind, sudden movements, or equipment wear. This conservative approach enhances the reliability of the lift and cultivates a culture of safety within the workplace. Thus, prioritizing safety by not exceeding this capacity is not only a best practice but a necessary protocol in preventing accidents and protecting the lives of workers.
