In terms of rigging, what does the term "dead weight" refer to?

In the context of rigging, the term "dead weight" primarily refers to the weight of the object being lifted. This is essential to consider when determining the load that a rigging system must support, as it directly affects the safety and efficiency of the rigging setup. Understanding the dead weight is crucial for both the design of the rigging system and the selection of the appropriate equipment, as it plays a significant role in ensuring that the load can be safely managed and secured.

While other terms, such as the weight of the rigging equipment itself or the total weight of all suspended items, may contribute to the overall load, "dead weight" specifically pertains to the weight of the object that is actively being lifted or moved. This distinction is important for accurate calculations in rigging operations, particularly in terms of safety and compliance with load limits. Knowing the dead weight allows riggers to select the correct apparatus, such as slings, shackles, and lifts, that can adequately support the load without exceeding their rated capacities.
