When are trial lifts required for personnel platforms?

• A. At the beginning of the shift, any time the crane is moved to a new location and when lifting routes change and new hazards arise.
• B. At the beginning of the shift only.
• C. Only after repairs.
• D. Never.

Answer: (A)

Trial lifts for personnel platforms are about verifying safe operation whenever conditions change. The idea is that the crane’s setup, the ground and wind conditions, the path the load will travel, and any potential hazards can alter the stability and safety of lifting with a personnel platform. Because of that, you perform a trial lift not only at the start of work but anytime you move the crane to a new location, when the lifting route changes, or when new hazards appear. This test confirms the platform can be raised and moved safely under the actual conditions, with the rigging secure, outriggers and ground support stable, clearances adequate, and the load within the crane’s capacity for that configuration. It helps catch issues like altered center of gravity, unexpected interference, or insufficient clearance before actual work begins.

Starting the shift sets a baseline, but it isn’t enough on its own because conditions can evolve as you relocate the crane, alter paths, or encounter new hazards. Trial lifts are not only about repairs or never required; they’re a practical safety step whenever the work environment or setup changes.
