。[Detailed Description of the Invention] Conventionally, when constructing Jasokianoprigs, etc., the legs were divided into multiple blocks and were sequentially loaded using a crane. Therefore, a large offshore crane with a high lifting height was required. However, the use of Jin's large offshore crane has the following drawbacks.
１）海上クレーン使用料が高価。1) Maritime crane usage fees are expensive.
２）作業能率が悪い。2) Poor work efficiency.
さらに脚が長くなると，大型海上クレーンでも。If the legs are longer, it can also be used for large offshore cranes.
つりあげ高さ不足で，搭載が不可能になる不具合がある
。There is a problem that the lifting height is insufficient, making it impossible to mount the product.
本発明は，上記欠点を除去しようとするもので，既に立

とからなることを特徴としている。Therefore, the leg mounting device of the present invention includes a casing that is provided so as to be vertically movable along a first leg that is erected, and a second leg that is mounted on the upper end of the first leg. In order to achieve this, the present invention is characterized in that it comprises a derrick projecting from the side of the casing in parallel with the first leg and rotatably about an axis to lift the second leg.

Figure 1 is a sectional view. 1 in the figure is the leg mounting device. 2 is the casing. 3 is a guide shoe that engages with a cord C provided on the side of the already mounted first leg A. The guide shoe 3 is removably connected to the casing 2 with bolts or the like. 4 is a pinion that meshes with the rack B of the first leg A. 5 is a motor (with a speed reducer) that rotates the pinion 4.

１の脚Ａの上面上に降ろす。(4) Loading and loading the legs: Once the second leg was lifted to a predetermined height, the derrick 6 was rotated around its axis and the second leg was brought directly above the first leg A. , onto the upper surface of the first leg A.
（５） 本装置の下降；再びモータを駆動して９本装
置１を元の位置まで降ろす。(5) Lowering the device: Drive the motor again to lower the device 1 to its original position.
（６） 本装置の離脱ニガイドシュー３を外し９本装
