PROBLEM TO BE SOLVED: To provide a position adjustment device capable of accurately adjusting the position of a structure suspended by a crane device even in an area inaccessible to a person.SOLUTION: A position adjustment device comprises: a plurality of guide rollers 11 provided so as to surround a structure accommodation hole 4; a plurality of moving mechanisms 12 for moving the plurality of guide rollers 11 between an initial position and a push-in position; a push-in amount detection sensor 14 for detecting the push-in amount of the guide rollers 11 by the moving mechanisms 12; and a control unit 15 for controlling the moving mechanisms 12 on the basis of detection results of the push-in amount detection sensor 14. When a suspended structure 2 moves to immediately above the structure accommodation hole 4 and moves to a position facing the plurality of guide rollers 11, the control unit 15 controls the moving mechanisms 12 to move the plurality of guide rollers 11 from the initial position to the push-in position.SELECTED DRAWING: Figure 1

    【課題】人の立ち入りが困難な領域であっても、クレーン装置により吊るされた構造物の位置を精度良く調整することができる位置調整装置を提供する。【解決手段】構造物収容穴4を取り囲んで設けられる複数のガイドローラ11と、複数のガイドローラ11を、初期位置と押込み位置との間でそれぞれ移動させる複数の移動機構12と、移動機構12によるガイドローラ11の押込み量を検出する押込み量検出センサ14と、押込み量検出センサ14の検出結果に基づいて移動機構12を制御する制御部15とを備え、制御部15は、吊るされた構造物2が、構造物収容穴4の直上に移動すると共に、複数のガイドローラ11と対向する位置に移動すると、移動機構12を制御して、複数のガイドローラ11を、初期位置から押込み位置に移動させる。【選択図】図1
