What is the primary purpose of using a tag line during transformer handling?

• A. To measure angle of lift
• B. To stabilize and guide the transformer away from obstacles
• C. To secure the transformer to the pole
• D. To supply power to the hoist

Answer: (B)

A tag line is used to control and steer the load, providing a secondary control point to stabilize the transformer and guide its movement away from obstacles. As the transformer is lifted or repositioned, wind and swing can push it off line or into poles, wires, or equipment; a ground crew member can pull or guide the tag line to maintain clearance and keep the load predictable for the operator. It’s not about measuring lift angles, securing the transformer to a pole, or supplying power to the hoist—those tasks rely on other equipment or procedures. Using a tag line properly reduces sway, enhances maneuverability, and improves overall safety during handling.
