Question 267 Deck General

The correct answer is A) Rider block taglines. The rider block is a component of the crane's rigging system, and the taglines are the ropes attached to the rider block to control its movement and positioning. This is the correct answer based on the typical components and rigging layout of a 30-ton pedestal crane, as depicted in illustration D045DG. The other options are incorrect because they do not accurately describe the item labeled "K" in the illustration. Cargo snaking cables, jib luffing cables, and manual slewing cables are different components of the crane's rigging system, but they are not the item labeled "K" in this specific illustration.
