When determining the "gross load", what is the best method to use?

To determine the "gross load" accurately, obtaining an accurate load weight and then adding the weight of the rigging is the best method. This approach ensures that you have a precise understanding of the total weight that the crane will be lifting. The gross load includes not only the weight of the primary load but also any additional components, such as slings, shackles, and other rigging equipment that contribute to the overall lifting weight.

This method minimizes the risk of underestimating or overloading the crane, which can lead to unsafe operating conditions, equipment failures, or accidents. By accounting for every aspect of the load, including rigging, operators can ensure they remain within the crane's rated capacity and that all safety protocols are adhered to.

Relying solely on weighing the load without considering rigging, adding rigging without weighing, or estimating based on size would not provide the comprehensive and precise information needed to ensure safe lifting operations.
