In theatre rigging, what does "dead weight" refer to?

In theatre rigging, "dead weight" refers specifically to fixed loads that remain in a constant position. This term is used to describe loads that do not change over time or with movement, such as the weight of scenery, equipment, or flown elements that are securely attached and do not shift. Understanding the concept of dead weight is crucial for rigging professionals, as it helps in calculating the overall load on rigging hardware and ensuring that all components are rated to handle the static weight without the risk of failure.

The idea of dead weight is important in rigging concepts to ensure safety and stability. Knowing how much weight is dead weight allows riggers to keep a clear understanding of how to balance additional dynamic loads or movable weights that may be introduced during a performance. Recognizing the difference between fixed loads and variable ones is essential in designing safe and effective rigging systems.

Dynamic loads that change position represent a different category of loads that require consideration of movement and varying forces, which is not applicable when discussing dead weight. Similarly, movable weights that are adjusted regularly do not fit this definition since they change position and do not provide consistent, fixed weight. Lastly, while weights used for counterbalancing may involve fixed or dynamic components, the term "dead weight"
