A critical lift is defined as any lift greater than what percentage of the rated crane capacity?

A critical lift is defined as any lift that exceeds 85% of the rated crane capacity. This threshold is established to ensure safety and minimize the risk of accidents during operations. Lifts approaching or exceeding this percentage increase the potential for failure due to various factors, including equipment limitations, load stability, and environmental conditions.

By identifying a lift as critical when it surpasses 85% of the crane's rated capacity, proper safety protocols can be put into place. This could involve more thorough planning, additional safety measures, and possibly the involvement of more personnel to manage the lift, ensuring all safety considerations are addressed.

The reason this percentage is particularly chosen lies in balancing operational efficiency and safety. Lifting beyond this margin can place significant strain on the equipment, increasing the chances of malfunction or hazard. Understanding this classification is crucial for anyone involved in crane operations and underscores the importance of adhering to safety guidelines in lifting practices.
