PROBLEM TO BE SOLVED: To provide an overhead crane which inhibits swinging and vibration of a wire when a lifting tool is moved in a height direction and can achieve high transportation efficiency of a lifting object.SOLUTION: An overhead crane 1 includes: a pair of guide rails 11 which is arranged side-by-side in parallel to each other with a predetermined interval; a girder 12 which is installed on the guide rails 11 in a direction intersecting with the guide rails 11 and travels on the guide rails 11; a trolley 13 which is provided so as to be able to travel on the girder 12 in a direction orthogonal to the guide rails 11 and is connected with a lifting tool 132; a lifting part 14 which supports the guide rails 11 from below and moves up and down the guide rails 11; and a control part 17 which controls a height of the lifting part 14.SELECTED DRAWING: Figure 1

    【課題】吊り具の高さ方向の移動を行う際に、ワイヤの揺れや振れの発生を抑え、吊り対象物の搬送効率を図ることができる天井クレーンを提供する。【解決手段】天井クレーン1は、所定の間隔をおいて互いに平行に並設された一対のガイドレール11、ガイドレール11の上でガイドレール11と交差する方向に架設され、当該ガイドレール11の上を走行するガーダ12、ガーダ12の上でガイドレール11と直交する方向に走行可能に設けられ、吊り具132が連結されたトロリ13、ガイドレール11を下方から支持し、ガイドレール11を昇降する昇降部14、および、昇降部14の高さを制御する制御部17を備える。【選択図】図1
