Description
本発明は、上記問題を解決することを課題とし、摺接面の磨耗を減らし、長時間に渡って可動顎の傾きを有効に防止できるとともに、可動顎の支持構造を簡素化し、組立修理作業の容易化を可能にする切断機を提供することを目的とする。
油圧ショベルに取付けられるフレームと、フレームに設けられた一対の顎とを備え、少なくとも一方の顎がフレームに対して揺動自在に取付けられており、フレームが左右の垂直板状部を備え、左右垂直板状部材の顎の取り付け部分に、円筒状部分を有する顎支持部材が配され、顎が、フレームへの取付部分にあけられた左右方向の貫通孔に圧入されて、貫通孔から突出した端部が可動顎支持部材の円筒状部分により揺動自在に支持された円柱状部材を備え、円柱状部材にあけられた軸方向貫通孔を貫通してフレームの可動顎支持部材により端部が固定状に支持されることで可動顎をフレームに取り付けるピンとを備え、可動顎の左右面の一部が、可動顎支持部材の円筒状部分の端面に当接している、ものである。
