Question 257 Deck General

The correct answer is D) All of the above. This is correct because twin pedestal cranes are typically equipped with the following features: A) A slew drive system provides for rotation of each crane, allowing the crane to rotate independently. B) Each crane is supplied with luff (boom elevation), hoist (load lifting), and slew (rotation) functions to provide full control over the crane's load handling capabilities. C) An independent slew drive system rotates the turntable, which is the base that the cranes are mounted on, allowing the entire crane structure to rotate. The other options are all true statements about the design and functionality of twin pedestal cranes, which is why the correct answer is D) All of the above.
