What is the guideline for balancing line sets?

• A. Line sets should always be kept in balance, and never rely on the rope lock to hold an unbalanced load.
• B. Balance is optional when the system is new.
• C. Balance only when the line is moving.
• D. Rope lock should be used to hold the balance.

Answer: (A)

Balancing line sets is essential for safe, controlled operation. When the two sides have equal tension, the load stays where you expect it to be and moves smoothly without pulling unevenly or drifting. An unbalanced load puts extra stress on one side, which can cause the load to swing, bind, or move unexpectedly, increasing the risk of injury or equipment damage. The rope lock isn’t meant to bear the full weight or hold an unbalanced load for any length of time; it’s a temporary restraint used during setup or to stop movement briefly, not a reliable, long‑term load-holding solution. So the guideline is to keep line sets balanced at all times and only use the rope lock as a secondary precaution after ensuring balance.
