PROBLEM TO BE SOLVED: To provide a roll suspending tool capable of performing crane suspending in a safe and easy way without tilting a roll unit in which a weight distribution is ununiform when an exchange of the roll unit is easily performed in a roll stand.SOLUTION: A suspension shaft 40 with which a hook 70 of a crane is engaged is swingably connected to an upper side of a suspending frame 20 with a slant lever 50. The slant lever 50 is pivoted at a position shifting in a horizontal direction relative to a gravity line of the supporting frame 20, and elastically held in an inclined status with a spring mechanism 60. In a state that the suspending tool is crane-suspended alone, a center of gravity of the suspending tool is positioned just under a suspending position. In a state that the suspending tool is crane-suspended while the suspending frame 20 cramps the roll unit downward, the spring mechanism 60 is elastically deformed, and the slant lever 50 stands up. The center of gravity of the suspending tool is apart from a position just under the suspending position toward the horizontal direction, and a combined center of gravity of the suspending tool and the roll unit is moved to near a position just under the suspending position. |
