Guideline for the Safe Use of Tag Lines
Tag lines play a critical role in controlling suspended loads, preventing uncontrolled rotation and keeping personnel at a safe distance. Cranes for You includes this guideline because proper tag-line use is essential for achieving Goal Zero in lifting, hoisting and specialised transport operations — especially in windy, congested or dynamic environments.
Summary of the Tag Line Guidance
- Purpose of tag lines — Maintaining control of suspended loads, preventing rotation, swinging or striking obstacles during lifting operations.
- Correct application — When and how tag lines should be attached, including recommended locations, rope types and safe grip techniques.
- Operator and rigger coordination — Clear communication rules between riggers, signalers and crane operators to ensure coordinated movements.
- Environmental considerations — Wind speed limits, line tension, pinch points and measures for avoiding entanglement or sudden load shifts.
- Prohibited practices — Situations where tag lines should not be used, such as near rotating machinery, in restricted zones, or when personnel must not be under the load.
Practical Relevance for Daily Lifting Work
Using tag lines correctly helps teams:
- keep riggers and operators safely outside the load’s danger zone;
- improve control over swinging, rotating or long loads;
- reduce collision risk during installation, assembly or load positioning;
- enhance communication and predictability during critical lifts;
- create consistent rules across lifting crews and contractors.
