What is the primary purpose of using a tag line when handling transformers?

• A. To measure the transformer load
• B. To connect to the testing equipment
• C. To stabilize and guide the transformer away from obstacles
• D. To raise the transformer more quickly

Answer: (C)

Using a tag line when handling transformers is about keeping control of the load. The tag line provides a secondary, hand-guided control that ground personnel use to stabilize the transformer and steer its movement. This helps prevent the load from tipping or swinging and keeps it on a safe path away from obstacles, lines, and other equipment. Transformers are heavy and top-heavy, so the tag line allows workers to make small, deliberate direction changes and maintain a steady, predictable motion during lifting and moving.

It isn’t used to measure the load, connect to testing gear, or speed up the lift. Those tasks involve different tools and procedures, whereas the tag line’s purpose is direct, physical control to keep the operation safe and precise.
