When must trail lift be made?

• A. Each location, beginning of each shift, when route changes
• B. At the end of each day only
• C. At the start of each shift only
• D. Never

Answer: (A)

A trial lift is a quick, initial lift used to verify that the crane setup, rigging, and lifting plan are safe under the current conditions. Because each worksite can present different ground conditions, clearances, and routes, it’s essential to perform this check every time you move to a new location, at the start of each shift, and whenever the travel route changes. This practice helps confirm that outriggers, mats, and cribbing are adequate, rigging is correct, and the load chart applies to the current setup. Doing it only at the end of the day or never would miss hazards that arise from changing sites or routes, increasing the risk of tipping, rigging failure, or collisions.
