LOWER LEADER DETACHING TOOL OF PILE DRIVER AND APPLICATION METHOD THEREOF
To provide a lower leader detaching tool of a pile driver and an application method thereof allowing simple and easy handling.SOLUTION: A lower leader detaching tool 31 of a pile driver detachably provided with a lower leader 20 by fastening a flange with a plurality of bolts on a lower end flange surface of a leader 19 guiding lifting of a work device 17 comprises: a bracket 32 detachably provided on the lower leader 20; and a suspension tool 33 connecting between the bracket 32 and the work device 17 to make the lower leader 20 follow lifting motion along a vertical direction of the work device 17, wherein the bracket 32 has a suspension tool attaching part 38 on which the suspension tool 33 is attached to hold the lower leader 20 in a suspended posture where an upper flange surface (an upper surface of a flange 20a) faces the lower flange surface (a lower surface of a flange 19a) of the leader 19 in a state that the tension is applied to the suspension tool 33.SELECTED DRAWING: Figure 2
【課題】簡易で取り扱いも容易な杭打機の下部リーダ着脱治具及びその使用方法を提供する。【解決手段】作業装置１７を昇降案内するリーダ１９の下端フランジ面に複数のボルトによるフランジ締結で下部リーダ２０を着脱可能に備えた杭打機の下部リーダ着脱治具３１であって、下部リーダ２０に着脱可能に設けられるブラケット３２と、該ブラケット３２と作業装置１７との間を連結して下部リーダ２０を作業装置１７の鉛直方向に沿った昇降動作に追従させる吊り具３３とを備え、ブラケット３２は、吊り具３３が取り付けられる吊り具取付部３８を有し、吊り具３３に張力を付与した状態で、下部リーダ２０をその上端フランジ面（フランジ２０ａ上面）がリーダ１９の下端フランジ面（フランジ１９ａ下面）と対面した宙吊り姿勢に保持してなる。【選択図】図２
