Abstract
A crane apparatus is disclosed. First traverser wire ropes are connected to a right connecting portion of a traverser, while second traverser wire ropes are connected to a left connecting portion of the traverser. First hoisting accessory wire ropes are passed over a right rope pulley via the traverser, and then connected to the traverser, while second hoisting accessory wire ropes are passed over a left rope pulley via the traverser, and then connected to the traverser. A hoisting accessory is suspended from the right and left rope pulleys. The crane apparatus enlarges the traversing range of the hoisting accessory, and increases work efficiency, without becoming upsized.
