徴とするダブルリンク式クレーン。 In a double-link type crane that lets out multiple hoisting ropes from the tip of the jib and uses these hoisting ropes in common to carry out cargo handling operations for containers and grab buckets, the tip of the jib has a rotatable structure. A sheave block is supported by the sheave block and has a sheave that engages with each of the hoisting ropes, and a wire rope is connected to the sheave block, and the wire rope is wound and let out to move the sheave block horizontally during container handling. a sheave block rotating means for horizontally separating the sheaves engaged with the hoisting rope from each other in the horizontal direction; The first method for correcting the amount of winding and unwinding of the wire rope mentioned above.
A wire rope correction means; and a second wire rope correction means for detecting the deflection of the tip of the jib and correcting the amount of winding and unwinding of the wire rope according to the change in the amount of deflection. Features a double link crane.
