Accordingly, the hoist crane 4 can be continuously moved along two or more side surfaces (actually, all four side surfaces) of the apartment house 100. That is,
Lifting work can be performed at any position over two or more sides (actually all four sides) of the apartment house 100.

In the above-described embodiment, when the lifting means is moved in the horizontal direction, the left and right rollers 48 of the moving section roll on one traveling rail 3 and move. For example, a configuration in which one roller 48 rolls and moves between two rails arranged in parallel may be used. In addition, although the running rail 3 is formed in a loop shape, at least a part of the running rail 3 may be curved, and for example, a case where the running rail 3 is not a loop but a line segment. In this case, stoppers for stopping the movement of the hoist crane 4 are provided at both ends in the longitudinal direction of the traveling rail 3 so that the hoist crane 4
It is desirable that the stopper can stop the movement of the hoist crane 4 when the end of the hoist crane 4 is reached.
