Question 494 Deck General

70% to pass

Most pedestal crane power is provided by _______________.

A Steam units
B Electro-hydraulic units
C Independent internal combustion power units
D All of the above
AI Explanation

The correct answer is B) Electro-hydraulic units. Pedestal cranes on US Coast Guard licensed vessels are typically powered by electro-hydraulic systems, which use electric motors to drive hydraulic pumps that provide the power for the crane's movements. This electro-hydraulic configuration is the most common and efficient method for powering pedestal cranes on commercial vessels. The other options are incorrect because steam units are an outdated power source for modern pedestal cranes, and independent internal combustion power units, while used in some applications, are less common than the electro-hydraulic systems required for Coast Guard certified vessels.
