Q

Which of the following statement(s) is/are TRUE regarding twin pedestal cranes?

🔍 Key Concepts

• Twin pedestal crane design and operation on cargo vessels or offshore units • Functions of a slew drive system and what motion it controls • Regulatory expectations for crane maintenance logs and records on board

💭 Think About

• Think about what physical motion a slew drive system controls on a crane and whether that matches the description given in option A. • Consider the difference between a simple luffing boom and a partial-level luffing boom: how does the load move when the boom is raised or lowered? • Ask yourself whether, under safety and regulatory frameworks, it would be reasonable or required to keep maintenance logs for each individual crane on a twin pedestal system.

✅ Before You Answer

• Verify what "slew" means in crane terminology (is it rotation, luffing, or something else?). • Confirm whether each boom on a twin pedestal crane typically has limited or full rotation, and how rotation is usually provided. • Check whether standard marine/industrial practice requires separate maintenance records for each crane rather than one combined record.
