What characteristic should be considered in the load working calculation?

In load working calculations, it is crucial to consider the weight of load attaching equipment because it directly impacts the total load that the hoisting equipment must manage. This consideration ensures that the hoisting equipment is not overloaded beyond its rated capacity, which could lead to unsafe operating conditions, including the risk of equipment failure or accidents.

When calculating the load, the total weight includes not only the actual load being lifted but also any additional components such as slings, hooks, and other attachments. These components can add significant weight, influencing the overall load on the system and requiring appropriate adjustments to ensure safety and compliance with regulations.

If other characteristics, such as the size of the derrick or the height of the mast, play a role in the operation, they do not directly influence the load calculations in the same manner as the weight of load attaching equipment does. The strength of the operator is also a consideration in overall operational safety, but it does not factor into the actual load calculation itself. Thus, the weight of load attaching equipment is the most pertinent characteristic for this specific calculation.
