PROBLEM TO BE SOLVED: To provide a scaffold device that allows a total height to be changed.SOLUTION: A scaffold device includes: a base frame 1 having transfer means T and movable in a lateral direction; a lifting frame 2 supported by the base frame 1 and may be lifted/lowered freely; a weight W connected to the lifting frame 2 and lifted/lowered along with the lifting frame 2; a vertical support post 11 for erecting the base frame 1 on four corners of a rectangular plane with the transfer means T in between; a movable support post 21 for holding the lifting frame 2 on the vertical support post 11 in a way that allows lifting/lowering; a handrail 4 installed on the movable support post 21; and a floor 3 connected to the movable support post 21. When the lifting frame 2 is lifted in relation to the base frame 1 by manual operation, a total height is increased, an inner space is formed above the rectangular plane when the lifting frame 2 is lifted to a highest point, the inner space being partitioned from outside by the handrail 4 and partitioned from a space below by the floor 3 for allowing a person to enter the floor 3. When the lifting frame 2 is lowered in relation to the base frame 1 by canceling the manual operation, the total height is reduced, and the weight W ascends when the lifting frame 2 is lowered and descends when the lifting frame 2 is lifted. |
