本考案は、輸送時にリーダをベースマシンの上
部に略水平に格納できる小型の杭打機のリーダ支
持装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a leader support device for a small pile driving machine that allows the leader to be stored substantially horizontally on the top of a base machine during transportation.
大型の杭打機にあつては、周知の如く、リーダ
をハ字状に配置した２本のバツクステー（シリン

向の調整は、２本のバツクステーを伸縮させるこ
とによつて行なつている。
As is well known, in the case of large pile driving machines, the leader is supported by two backstays (cylinders) arranged in a V-shape (three-point support system), and the left and right adjustment of the leader is performed using the two backstays (cylinders). This is done by expanding and contracting the backstay.
一方小型の杭打機は、輸送時にリーダをベース
マシンの上部に略水平に格納する必要があるが、
上記３点支持方式では、構造状バツクステーを取
り外す必要があることから、３点支持方式を採用
できない。 On the other hand, with small pile driving machines, the leader needs to be stored almost horizontally on top of the base machine during transportation.
In the three-point support method described above, it is necessary to remove the structural backstay, so the three-point support method cannot be adopted.

とができない。 For this reason, in the case of small pile driving machines, the leader is supported by one or two parallel undulating cylinders, and the leader is stored approximately horizontally above the base machine during transportation. However, with this configuration, the leader cannot be adjusted in the left-right direction during work due to the expansion and contraction of the undulating cylinder.
このため、作業時の杭の芯合せ用に、リーダ調
整装置を別途設ける必要がある。 Therefore, it is necessary to separately provide a leader adjustment device for centering the pile during work.
そこで、比較的小型の杭打機において、輸送時

30839号公報に開示されている。 Therefore, in a relatively small pile driving machine, the leader can be stored almost horizontally on the top of the base machine during transportation, and the pile driver is equipped with a leader adjustment device for centering the pile during work, for example.
It is disclosed in Publication No. 30839.
