Then, when one inner carry 12A is lifted, the two inner carry 12A are connected to each other by a wire W so that the other inner carry also works together at the same time, so that the wire W can be guided. While walking to the upper guide roller (R1) installed on both sides of the cross beam 30, one side is connected to the upper side of the inner carry (12A) and the other side through the lower guide roller (R2) located at the bottom of the post (10) It is connected to the lower part of the inner carry 12A.

Therefore, when the hydraulic cylinders 12 on both sides are operated at the same time, the wire W connected to the upper portion of the inner carry 12A rises up and the inner carry 12A on the opposite side passes through the lower guide roller R2 located at the bottom. It is connected to the lower side of the inner carry 12A. As the inner carry 12A pulls the wire W when it is raised, the wire W is pulled as much as it is released from one side, so that the wire W always maintains the proper tension. It becomes a state.
