Question 383 Deck General

The correct answer is C) allowable load. The load chart of a crane is used to determine the maximum allowable load that can be lifted at a given boom length and load radius. This information is critical for the crane operator to ensure that the crane is not overloaded, which could lead to structural failure or instability. The load chart takes into account factors such as the crane's capacity, configuration, and stability to provide the operator with the safe working load limits. The other answer choices are incorrect because they do not directly relate to the primary function of the load chart, which is to specify the allowable load. The load chart does not determine the maximum counterweight required (A), the minimum horsepower needed (B), or the hoist rope strength (D).
