Summary:PROBLEM TO BE SOLVED: To improve reliability by facilitating confirmation that a jack-up device is in a retraction position in conducting a retraction operation.SOLUTION: Each jack-up device 120 can be disposed in a work position where a tip side is radially disposed outward and in a retraction position where an interval between a pair of crawlers can extend or contract, and includes a detection sensor 50 for detecting that the jack-up device 120 is in the retraction position.SELECTED DRAWING: Figure 5 【課題】リトラクト操作をする際、ジャッキアップ装置がリトラクト位置であることの確認が容易にして信頼性を向上する。【解決手段】各ジャッキアップ装置１２０は、先端側が外方に向かって放射状に配置される作業位置と、一対のクローラの間隔が拡大または縮小可能となるリトラクト位置とに配置可能であり、ジャッキアップ装置１２０がリトラクト位置であることを検出する検出センサ５０を備える。【選択図】図５
