OSHA does not have one critical-lift rule that applies to every crane job. Its steel-erection standard defines a critical lift as one that exceeds 75% of rated capacity or uses more than one crane or derrick. That definition appears in 29 CFR 1926.751 and is limited to Subpart R steel erection.
For construction lifts in which more than one crane or derrick supports the load, 29 CFR 1926.1432 requires:
- a plan developed by a qualified person;
- engineering expertise when that qualified person determines it is needed;
- a lift director who is both a competent and qualified person, or a competent person assisted by one or more qualified persons; and
- a meeting in which the lift director reviews the plan with everyone involved.
Section 1926.1432 does not require the plan to be written and has no subsection (e). Other OSHA provisions separately govern rated capacity, inspections, power lines, ground conditions, signaling, and hoisting personnel. Which provisions apply depends on the work being performed. ASME standards may be adopted by a contract, site program, or another authority, but they are not automatically federal OSHA requirements merely because a lift is called critical.
