COLUMN MEMBER CUTTING DEVICE
To provide a column member cutting device having a function of appropriately holding and cutting a cylindrical column member having a large diameter constituting a steel tower or the like.SOLUTION: The distance between a first rotation shaft 731-1 and a turning center line RL can be varied while keeping the first rotation shaft 731-1 of a first circular saw 710-1 parallel to the turning center line RL, and the distance between a second rotation shaft 731-2 and the turning center line RL can be varied while keeping the second rotation shaft 731-2 of a second circular saw 710-2 parallel to the turning center line RL. By increasing the distance between the first rotary shaft 731-1 and the turning center line RL and the distance between the second rotary shaft 731-2 and the turning center line RL respectively, it becomes easy to introduce a column member to a position held by a holding part 71 even if the column member has a relatively large diameter.SELECTED DRAWING: Figure 12
【課題】鉄塔などを構成する径の大きい筒状の柱部材を適切に把持して切断する機能を持った柱部材切断装置を提供する。【解決手段】第１丸鋸７１０−１の第１回転軸７３１−１を旋回中心線ＲＬに対して平行に保ちつつ、第１回転軸７３１−１と旋回中心線ＲＬとの距離を変化させることか可能であり、また、第２丸鋸７１０−２の第２回転軸７３１−２を旋回中心線ＲＬに対して平行に保ちつつ、第２回転軸７３１−２と旋回中心線ＲＬとの距離を変化させることか可能である。第１回転軸７３１−１と旋回中心線ＲＬとの距離及び第２回転軸７３１−２と旋回中心線ＲＬとの距離をそれぞれ広げることによって、比較的径の大きい柱部材であっても、把持部７１により把持される位置へ柱部材を導入し易くなる。【選択図】図１２
