What does the term "live load" refer to in rigging?

The term "live load" in rigging specifically refers to the weight of the load being lifted, which includes any dynamic forces acting on that load. This concept is crucial for riggers to understand because the live load encompasses not only the static weight of the object but also any additional forces that may arise from factors such as movement, acceleration, or environmental conditions.

When lifting a load, it is essential to consider these dynamic forces to ensure the safety and effectiveness of the rigging setup. If only the static weight were considered, it might lead to insufficient calculations for the rigging gear's capacity, potentially resulting in dangerous situations. By recognizing the live load appropriately, riggers can apply the correct safety factors and select appropriate lifting equipment, ensuring compliance with safety standards and regulations.

Understanding the distinction between live load and other types of loads, such as dead loads, enhances a rigger's competency in making informed decisions regarding load handling, gear selection, and rigging methods. This comprehension is vital for preventing accidents and promoting safety in lifting operations.
