🔍 Key Concepts

• Crane structure terminology: pedestal, turntable, mast, pillar • On a pedestal crane, the rotating part sits on top of a fixed support • Look closely at where label G is pointing in relation to the upper works and the vertical column

💭 Think About

• Ask yourself: Is item G a fixed support attached to the deck, or is it the part that allows the crane to rotate (slew) horizontally? • Compare item G with item H: which one clearly continues down as the main vertical column, and which one is a ring or interface between moving and fixed parts? • For the terms mast and pillar: which of these usually describes a tall vertical member instead of a thin ring or interface piece?

✅ Before You Answer

• Verify which part of the crane in the drawing is fixed to the ship’s structure and which part rotates with the boom and housing. • Confirm whether G looks like a ring/interface between two pieces or a full vertical column by itself. • Match the visual function of G to the correct term: base column, rotating table, vertical tower/mast, or simple post/pillar.
