To provide a pile driving machine including a leader bracket, which makes positioning of a pin insertion hole easy and which can quickly and easily carry out an attachment work to a revolving super structure, with a simple structure.SOLUTION: A first pin insertion hole 32c provided in a leader bracket attaching arm 32 and a first pin insertion hole 28c provided in a connection arm 28 are formed at a position of a state where a first connection pin 33 can be inserted, in a state in which a guide member 31 provided in the connection arm is engaged with a support shaft 35 provided in the leader bracket attaching arm, when a leader bracket 16 is rotated in a vertical direction around the support shaft. A second pin insertion hole 32d provided in the leader bracket attaching arm and a second pin insertion hole 28d provided in the connection arm 28 are formed at a position of a state where a second connection pin 34 can be inserted, when the leader bracket is rotated in a vertical direction around the first connection pin inserted into the first pin insertion hole, and the engaged state of the guide member with the support shaft is released.SELECTED DRAWING: Figure 5
【課題】簡単な構造でピン挿通孔の位置合わせを容易にして、上部旋回体への取付作業を迅速かつ容易に行えるリーダブラケットを備えた杭打機を提供する。【解決手段】リーダブラケット取付腕３２に設けられた第１ピン挿通孔３２ｃと連結腕２８に設けられた第１ピン挿通孔２８ｃとは、連結腕に設けられたガイド部材３１がリーダブラケット取付腕に設けられた支持軸３５に係止した状態で、支持軸を中心としてリーダブラケット１６を上下方向に回動させたときに第１連結ピン３３が挿通可能な状態になる位置に形成され、リーダブラケット取付腕に設けられた第２ピン挿通孔３２ｄと連結腕２８に設けられた第２ピン挿通孔２８ｄとは、第１ピン挿通孔に挿通した第１連結ピンを中心としてリーダブラケットを上下方向に回動させてガイド部材と支持軸との係止状態が解除されたときに第２連結ピン３４が挿通可能な状態になる位置に形成されている。【選択図】図５
