Figure d), crane test (Figure 3e) was carried out, and the crane test (Figure 3 e) was carried out, and in the present invention, the lower part 3' of the leg was connected to the base concrete 2.
An anchor bolt 7 supporting the lower part 3' of the nine legs and a foundation 8 for the anchor bolt are set by burying the lower part 3' in the lower leg part 3' (FIG. 4b). Setting of turning section 4 (Fig. 4 C) and setting of foundation concrete 2 (Fig. 4 a)
is a translational work. By 29, counterweight 5
, Installation of boom 6 (Fig. 4 d), Crane test (Fig. 4)
The work shown in Figure e) has been brought forward and the jib crane can be put into operation earlier.
