70% to pass

Which piece(s) of equipment is/are required to "twin-up" 30-ton pedestal cranes aboard a crane vessel?

A Equalizing beam
B 20-foot container spreader
C Portable power swivel
D All of the above
AI Explanation

The correct answer is A) Equalizing beam. To "twin-up" 30-ton pedestal cranes aboard a crane vessel, an equalizing beam is required. The equalizing beam helps distribute the load evenly between the two cranes, ensuring safe and stable lifting operations. This is a regulatory requirement specified in the US Coast Guard regulations for crane vessel operations. The other options (B, C, and D) are not correct, as a 20-foot container spreader and a portable power swivel are not necessary for the specific task of twinning up 30-ton pedestal cranes. The correct equipment for this task is the equalizing beam.
