What is the supervisor's role during crane operations?

• A. Operate the controls during every lift.
• B. Approve lift plans, assign personnel, monitor safety, and authorize lifts within risk controls and site policies.
• C. Only handle administrative tasks, not involved in lifts.
• D. Design the crane and machine components.

Answer: (B)

The supervisor’s job in crane operations is to be the on-site safety and coordination authority. They ensure the lift is properly planned and executed safely by approving the lift plan, assigning the right personnel (operator, signal person, riggers), monitoring safety throughout the lift, and authorizing lifts only after confirming that risk controls and site policies are in place. This means checking that the lift plan covers weight, rigging, center of gravity, method, weather and ground conditions, and that everyone understands their roles and signals. The supervisor keeps an eye on ongoing safety, enforces clear communication, maintains exclusion zones, and ensures procedures and PPE are followed.

They don’t operate the crane on every lift, and they aren’t the ones who design the crane or its components. Those tasks belong to the operator for control execution and engineers for design. The supervisor’s value lies in planning, safety oversight, and the formal authorization to lift within the established risk controls and site rules.
