To provide a tubing device comprising a lifting device cradle having a simple configuration and allowing a mounting position to be easily changed.SOLUTION: In a tubing device, at an upper part of a chuck frame 16, there are provided a work deck 29 comprising an opening 24 corresponding to a position of a casing insertion hole and a lifting device cradle 32 capable of being attached to and detached from a floor surface of the work deck. The work deck has a deck protrusion 31 protruding outward from the chuck frame. The lifting device cradle is selectively attached to two locations on the floor surface determined by rotating by 180 degrees around a central axis of the casing insertion hole as an axis of rotational symmetry, and in the attached state, has a cradle protrusion 33 protruding outward from the work deck and a stay member 34 detachably mounted between the cradle protrusion and the chuck frame. The stay member consists of an inner stay member 37 and an outer stay member 38 that are mechanically fastened to each other via a fixing portion 36 provided at an outer end of the deck protrusion.SELECTED DRAWING: Figure 4
【課題】簡単な構成で取付位置の変更を容易に行うことができる昇降装置用架台を備えたチュービング装置を提供する。【解決手段】チュービング装置は、チャックフレーム１６の上部に、ケーシング挿通孔の位置に対応する開口部２４を備えた作業デッキ２９及び該作業デッキの床面に着脱可能な昇降装置用架台３２が設けられ、作業デッキは、チャックフレームの外方に張り出したデッキ張出部３１を有し、昇降装置用架台は、ケーシング挿通孔の中心軸を回転対称軸として１８０度回転させて定まる床面２箇所に選択的に取り付けられ、該取り付け状態で、作業デッキの外方に張り出した架台張出部３３と、該架台張出部とチャックフレームとの間に着脱可能に跨設されたステー部材３４とを有し、ステー部材は、デッキ張出部の外端に設けられた固定部３６を介して互いに機械的締結がなされる内側ステー部材３７と外側ステー部材３８とからなる。【選択図】図４
