Heavy lifts greater than what percentage of rated crane capacity are classified as critical lifts?

Heavy lifts that exceed 85% of the rated crane capacity are classified as critical lifts. This classification is important for safety and operational planning, as critical lifts involve higher risks due to the increased load nearing the maximum capacity of the crane. These lifts require thorough planning, increased oversight, and often special considerations such as additional rigging, more personnel to ensure safety, and detailed lift plans to mitigate the risks involved.

Understanding the percentage that classifies a lift as critical is essential for maintaining a safe working environment and ensuring compliance with safety regulations and guidelines in lifting operations. Recognizing that a lift above 85% of a crane’s rated capacity falls into this category guides operators and crews to implement necessary precautions and procedures to conduct the lift safely.
