A critical lift is any hoisting operation that
- exceeds 75% of a crane’s rated capacity,
- requires multiple cranes, or
- involves elevated risk factors.
Under OSHA 29 CFR 1926 Subpart R (1926.751) and industry consensus standards such as ASME B30.5, these operations require rigorous, documented preparation due to the severe consequences of failure.
Beyond load capacity thresholds, lifts are classified as critical when
- maneuvering over occupied areas,
- encroaching on the minimum clearance distances of energized power lines, or
- hoisting irreplaceable, high-value equipment.
