Question 270 Deck General

The correct answer is C) It is required to "twin-up" 30-ton pedestal cranes. The equalizing beam on a crane vessel is used to connect two cranes together, allowing them to work in tandem or "twin-up" to lift heavier loads. This is a regulatory requirement for pedestal cranes with a capacity of 30 tons or more, as the equalizing beam helps distribute the load evenly between the two cranes. The other options are incorrect - option A refers to rigidly connecting two cranes, which is not the purpose of the equalizing beam. Option B is about using the beam to lift light loads, which is not its primary function. Option D is about allowing rotation of the hook, which is a separate feature not related to the equalizing beam.
