What does the term "dead load" refer to?

• A. The load in motion
• B. The weight of the rigging system and attached fixtures
• C. The weight of live cargo
• D. The maximum weight a system can handle

Answer: (B)

The term "dead load" specifically refers to the weight of the rigging system itself, along with any attached fixtures that are not in motion. This can include the load-bearing components such as slings, chains, or blocks. Understanding dead loads is crucial for rigging because they must be considered when calculating how much additional weight can safely be added to a load for lifting.

This concept is vital in ensuring that the rigging system remains stable and that the combination of dead loads and any live loads (the weight of actual cargo being lifted) does not exceed the system's capacity. Correctly identifying and accounting for dead loads helps prevent accidents and structural failures during hoisting operations.
