When the lifting device 5) is lifted, it is not caught in the groove. On the other hand, when the working stage 1 (that is, the lifting device 5) is lowered while being urged by the groove of the track portion 214, it is caught by the groove. The claw portion has an arbitrary shape (for example, a shape in which the upper part moves along the groove and the lower part is caught in the groove). When the operator operates the release portion 52 (for example, an operation of pressing the release portion 52 downward), the claw portion moves away from the groove of the track portion 214 against the urging force of the spring portion. When the work stage 1 is allowed to descend, and when the worker stops the operation of the release portion 52 (that is, when the operator does not operate), the claw portion is pressed against the groove of the track portion 214 by the urging force of the spring portion. Thus, the work stage 1 is configured to be prohibited from descending.

  First, each component in a disassembled state of the mobile scaffold device 900 is carried into a work place where the mobile scaffold device 900 is used for work. In this case, since each component is relatively small and disassembled, one or two workers can carry in relatively easily.

  Next, considering the dimensions of the mobile scaffold device 900 of FIG. 1, four moving parts 3 are installed, and the outrigger 32 of FIG. 8 is attached to each of the installed moving parts 3.

Thus, the mobile scaffold device 900 shown in FIG. 1 is assembled. In FIG. 1, the drill 82 is not shown for convenience of explanation.

(Disassembly method)
Next, a disassembly method for disassembling the mobile scaffold device 900 will be described. The specific procedure of the disassembling method is arbitrary. For example, by performing the disassembling procedure corresponding to the procedure of the assembling method from the side opposite to the procedure of the assembling method, Since it can be disassembled into parts, detailed description is omitted.

(how to use)
Next, a method for using the mobile scaffold device 900 will be described. Here, for example, the usage method will be described by exemplifying a case where four workers perform work.

  First, each worker pushes or pulls the mobile scaffold device 900 to move it, for example, to the vicinity of a wall of a building that is a target for work. In this case, since the mobile scaffold device 900 is fixed to the ground by the outrigger 32, the mobile scaffold device 900 is moved after removing the outrigger 32 or loosening the fixing to the ground before the movement, After the movement, the outrigger 32 is attached and the mobile scaffold device 900 is grounded and fixed to the ground (the same applies to the case where the mobile scaffold device 900 is moved away from the building wall as described later).

  Next, each worker opens the door portion 113 of FIG. 4 in the short frame 11 and gets on the work stage 1, and then simultaneously operates the two drills 82 of FIG. 16 to rotate forward (rotate). . In this case, the rotational force of each drill 82 is transmitted to the lifting device 5, and the rotational driving mechanism of the lifting device 5 is rotated by the transmitted force while meshing with the groove of the track portion 214 of the mast member 21. As a result, the working stage 1 supported by the lifting device 5 rises together with the lifting device 5. Here, since the operator does not operate the release portion 52, the above-described claw portion (not shown) is urged toward the groove side of the track portion 214 by the above-described spring portion (not shown). Is moved along the groove and the lower part is caught in the groove, so that the claw part is not caught in the groove of the track part 214 during ascending.

  Next, when it rises to a predetermined position, each worker stops the operation of the drill 82 and performs an arbitrary work (for example, new construction work, repair work, etc.) on the ceiling or wall of the building. In this case, the aforementioned claw portion (not shown) is urged to the groove side of the track portion 214 by the spring portion (not shown), so that the claw portion is caught in the groove of the track portion 214. Since the work stage 1 is prevented from descending unexpectedly, work safety can be ensured.

  Next, after the work is completed, each worker operates the release unit 52 of FIG. 16 attached to the four lifting devices 5 to permit the lowering. In this case, since the operator operates the release portion 52, the above-described claw portion (not shown) is separated from the groove of the track portion 214 against the urging force by the spring portion. The part can be lowered without being caught in the groove of the track part 214. Then, one of the two drills 82 in FIG. 16 is simultaneously operated and reversed (rotated). In this case, the rotational force of the drill 82 is transmitted to the lifting device 5, and the rotational drive mechanism of the lifting device 5 is rotated by the transmitted force while meshing with the groove of the track portion 214 of the mast member 21. The working stage 1 supported by the lifting device 5 is lowered together with the lifting device 5. Here, for example, since gravity exists, the elevating device 5 can be lowered to a smaller rotational force than when the elevating device is raised, so that one drill is provided in each of the four elevating devices 5 as described above. By operating 82, it is possible to lower.

  Next, each worker opens the door 113 shown in FIG. 4 in the short frame 11 and gets off the work stage 1, and then pushes or pulls the mobile scaffold device 900 to perform work. For example, keep away from building walls. This completes the description of the usage method.

  According to the mobile scaffold device described in appendix 14, by providing the auxiliary work stage provided outside the work stage, for example, the position that does not reach the work stage is also used by using the auxiliary work stage. Since work can be performed, it is possible to improve convenience. In addition, since the attachment work stage is detachable, for example, the attachment work stage can be used only when necessary, so that convenience can be further improved.

  According to the mobile scaffolding device according to attachment 15, for example, by providing the swing reduction means for reducing the swing of the work stage, the safety of the worker who is working on the work stage is improved. This also makes it possible to prevent the worker from feeling uncomfortable.

  According to the mobile scaffold device described in appendix 16, by providing the balance control means for controlling the balance of the mobile scaffold device, for example, it is possible to prevent the mobile scaffold device from falling down, and thus safety is improved. It is possible to secure.
