What should a lift plan do when obstacles are present in the load path?

• A. Identify obstacles, plan a safe path, ensures clearance margins, and assigns a spotter.
• B. Ignore obstacles with special signals.
• C. Remove obstacles with ground crew.
• D. Increase speed to pass obstacles.

Answer: (A)

When obstacles are in the load path, the lift plan must address safety through proactive path planning and clear communication. The key step is to identify what could interfere with the load—structures, equipment, and personnel—and then map out a safe travel route that keeps the load within a defined clearance margin from any obstacle. This includes considering the crane’s geometry, load size, rigging, wind effects, and potential swing, so the chosen path remains controllable and predictable throughout the lift.

Assigning a spotter is essential because someone on the ground can provide real-time visibility, watch for hidden hazards, and relay accurate signals to the operator as obstacles move or as the load changes position. This coordination helps ensure the crane operator can adjust the path promptly and safely, rather than relying on guesswork.

Other approaches fail because they ignore essential safety controls: signaling without proper obstacle assessment can be misinterpreted; trying to remove obstacles during a lift can be dangerous or impractical; and increasing speed to “get past” obstacles greatly raises the risk of collision, tip-over, or loss of control. The safest and most effective approach is thorough planning, maintaining safe clearances, and active ground supervision.
