How does wind affect lifting tall electrical components?

How does wind affect lifting tall electrical components?

• A. It reduces load capacity and helps stabilize the load.
• B. It adds lateral load and can cause sway; apply wind limits, use guy lines or spreaders, and consider delaying the lift.
• C. It only affects velocity but not sway.
• D. It only affects operator visibility.

Answer: (B)

Wind on a tall electrical lift creates lateral forces on the load and the rigging, and the wind can push the component sideways, causing it to sway or oscillate as it’s lifted. This is especially risky with tall, slender items that present a large wind profile, since gusts can rapidly change direction and speed, making control difficult and increasing the chance of contact with structures or人员, or placing unexpected side loads on slings and equipment. The best approach is to plan for wind limits based on the crane and load, and pause or delay the lift if those limits are exceeded. Use stabilizing measures like guy lines or spreaders to reduce sway and distribute loads more evenly, and adjust the lift plan to minimize exposure to wind (shorter lift, different path, or waiting for calmer conditions). These steps specifically address how wind adds lateral load and causes sway, improving safety and control during the lift.
