70% to pass

The boom indicator tells the operator at what angle the boom is compared to the _______________.

A horizontal position of the boom
B vertical position of the boom
C horizontal position of the load being lifted
D vertical position of the load being lifted
AI Explanation

The correct answer is A) the horizontal position of the boom. The boom indicator on a crane or derrick provides the operator with information about the angle of the boom relative to the horizontal. This is an important safety feature, as the boom angle affects the stability and load capacity of the crane. Knowing the precise boom angle allows the operator to ensure the load is being lifted within the safe operating parameters specified by the crane's manufacturer. The other answer choices are incorrect because they do not accurately describe what the boom indicator is designed to measure. The boom indicator does not provide information about the vertical position of the boom or load, only the horizontal angle.
