A moving device for a movable scaffold is provided to remove the frictional force generated at initial movement by moving a scaffold using rolling method. A moving device for a movable scaffold contains: pier brackets(110) installed on right and left sides of piers detachably; right and left workbenches(500,600) installed on the upper part of the pier bracket to let a worker conduct operations; a rolling device(900) installed on the right and left workbenches to make a rolling contact with the base of right and left main girders(200,300) to be moved longitudinally and composed of a base(910) installed to be projected to the right and left workbenches, two or more rollers(920) and a roller fixing member(930) fixed to the base and installed with the roller rotatively; a jack(950) installed to one side of the right and left main girders to be attachable/detachable using the rolling device; a traction device(980) connected to the roller fixing member of the rolling device and the jack to pull the jack to approach the rolling device and to make the right and left main girders move on the rolling device; and a reduction device composed of a wedge member(992) fixed to the traction device by a connecting member(991) and provided with a wedge unit, a wedge hole formed on a hollow guide member to penetrate the wedge unit, and a friction member installed in the hollow guide member to reciprocate vertically and provided with a friction unit rubbed against the base of the right and left main girders and a wedge hole fitted with the wedge unit via the wedge hole of the hollow guide member. |
