What is counterweight loading?

• A. The process of bringing equipment into the theater to begin a production.
• B. The process of placing the correct weights on the arbor to balance the load on a batten.
• C. The process of removing equipment after a production.
• D. A designated boundary to keep people away from hazards.

Answer: (B)

In a counterweight fly system, counterweight loading is the process of placing the correct weights on the arbor to balance the load on a batten. This balancing lets the scenery move up and down smoothly and safely, because the weight of the scenery and the batten is counteracted by the weights on the arbor. The right weights are chosen to match the load (often plus a little extra for friction and safety), and they are secured so the system stays balanced during operation. Proper loading keeps the system within its rated capacity and minimizes the risk of uncontrolled movement if the lift line is released. This is distinct from load-in (bringing equipment into the theater), load-out (removing equipment after a production), or a safety boundary that keeps people away from hazards.
