What does the term "load working" refer to?

The term "load working" refers specifically to the external load applied to the derrick. This is essential for understanding how much weight the derrick is handling during operation. Knowing the load working allows operators to assess what safety measures need to be implemented and ensures that they remain within the operational limits of the equipment. This concept is crucial for maintaining the structural integrity of the derrick and ensuring safe lifting operations.

By considering the external load in practice, operators can prevent overload situations that could lead to equipment failure or accidents. In this context, understanding the distinction between the load working and the other options, such as the weight of physical components or the maximum capacities, provides clarity on load management during hoisting tasks.
