PROBLEM TO BE SOLVED: To provide a boom transport fixing device capable of reducing an occupied space necessary for disassembling and assembling operations of a revolving frame and a boom.SOLUTION: A fixing device 100 for transporting a multi-stage boom 4 installed on a loading platform of a transport vehicle 90 and having a base end side boom 41 mounted rotatably to a boom mounting part of a crane and a distal end side boom 45 extendable with respect to the base end side boom comprises: a distal end side boom fixing device 110 fixed on the vehicle front side of the loading platform for fixing the distal end side boom on the loading platform while fixing a tip of the distal end side boom; and a base end side boom support device 120 fixed on the vehicle rear side of the loading platform for slidably supporting the base end side boom with a roller. When the base end side boom is extended in a state of fixing the tip of the distal end side boom by the distal end side boom fixing device, the base end side boom slides on the roller and moves to the rear part of the vehicle while the position of the distal end side boom is unmoved.
【課題】旋回フレームとブームをとの分解組立作業時に必要な占有スペースを削減できるブーム輸送用固定装置を提供する。【解決手段】輸送車両90の荷台に設置され、クレーンのブーム取付部に回動可能に取り付けられる基端側ブーム41、および基端側ブームに対して伸縮可能な先端側ブーム45とを有する多段式ブーム4の輸送用固定装置100において、荷台の車両前方側に固定され、先端側ブームの先端部を固定して先端側ブームを荷台上で固定する先端側ブーム固定装置110と、荷台の車両後方側に固定され、基端側ブームをローラで滑動可能に支持する基端側ブーム支持装置120とを備え、先端側ブームの先端部を先端側ブーム固定装置で固定した状態で基端側ブームを伸長させたとき、先端側ブームの位置は不動のまま、基端側ブームがローラ上を滑動して車両後方に移動するようにした。【選択図】図9
