後は、ジブ上方部分５を他のピン１１を中心に旋回させ
、鋏状に折り畳むことができる。The lower jib part 4 and the upper jib part 5 are connected to each other by pins 10.11, so that after removing one pin 10 the upper jib part 5 can be pivoted around the other pin 11 and the scissor-shaped It can be folded into.
ロッド１２の一端は、バランスウェイト３ａの領域に設
けられた上部車輛３上の支承部１３に可動に支持されて
おり、他端はジブ上方部分５の下方の３分の１のところ
で回転点１４に旋回可能に支持されている。One end of the rod 12 is movably supported in a bearing 13 on the upper vehicle 3 in the area of the balance weight 3a, and the other end is supported at a pivot point 14 in the lower third of the upper part 5 of the jib. It is pivotably supported.
ジブを真直に立てたシ、引込めたりすることは、液圧シ
リンダ１５によって行われる。A hydraulic cylinder 15 is used to straighten and retract the jib.
この液圧シリンダは上部車輛３０回転点１６とジブ下方
部分４０回転点１７に支持されている。This hydraulic cylinder is supported at the upper vehicle 30 rotation point 16 and at the jib lower part 40 rotation point 17.
アーム６は、ジブ上方部分５の回転点１９とアーム６０
回転点２０に枢着されている液圧シリンダ１８によって
、旋回される。The arm 6 is connected to the point of rotation 19 of the upper part 5 of the jib and the arm 60
It is pivoted by means of a hydraulic cylinder 18 which is pivoted at the rotation point 20.
この作動態様は次の通シである：ジブ下方部分４が真直
に立っている状態でピン１０を取外した後、液圧シリン
ダ１５を縮少する方向に負荷する。The mode of operation is as follows: after removing the pin 10 with the lower part 4 of the jib erect, the hydraulic cylinder 15 is loaded in the direction of retraction.
このことによシ、ジブ上方部分５が、ロッド１２により
、ジブ下方部分４に対してピン１１の周りを回転し、ジ
ブ部分４，５がグラフパケット８と共に、第２図に示さ
れた位置に折り畳まれる。This causes the upper jib part 5 to rotate about the pin 11 by means of the rod 12 relative to the lower jib part 4, and the jib parts 4, 5, together with the graph packet 8, to the position shown in FIG. folded into.
それによって、移動式掘削機は道路走行可能な状態にな
る。The mobile excavator is thereby ready for road use.
