1) According to the inventions of claims 1 to 10, a single lifting device is constructed such that each column is pivotally attached and can be folded, and the upper part of the stairs is pivotally attached to the upper floor and the lower part is slidable. Since it is pivotally attached to the slide stage, the entire lifting device, lifting tower, and transfer device are also vertical, can be inclined, and can be folded compactly by removing the brace.
[0086]
2) Similarly, it can be placed along slopes such as sloped mountains and hills, and various operations can be performed while moving up and down stairs along the slope.
[0087]
3) According to the transfer device of claims 8, 9, and 10, the worker can move up and down along the slope via the steps on the lift tower side, and the work gantry can be raised and lowered along the slope through the lift rail. Therefore, the machine and other equipment can be mechanically transported to the work gantry, improving workability and increasing the speed.
[0088]
In addition, even when the slope construction site extends upward along the slopes of mountains and hills, there is no need to add a transport device or reassemble upwards to assemble or disassemble a large scaffold each time, The machine can be transported freely and the operator can move up and down, so that the construction can be simplified and the cost can be reduced.
[0089]
4) According to the eleventh to sixteenth aspects of the present invention, the members constituting the single lifting device are detachably coupled each time. Therefore, at construction sites where a crane or other machine cannot be transported or installed. An operator can arbitrarily assemble or dismantle.
