ATTACHMENT SHIM FOR CONSTRUCTION MACHINE AND ATTACHMENT METHOD THEREOF
To provide an attachment shim for a construction machine which cannot only reduce a gap created between an arm of the construction machine and an attachment but facilitate detachment thereof.SOLUTION: A shim 5 provided with elastic material attached on a circumference of the pin in a gap G formed between an arm 2 and an attachment 4 attached on the arm of a construction machine 1 such as a power shovel a dump-truck and like through a pin 3 is formed in an annular shape provided with a predetermined width and partially provided with a discontinuous part H, wherein a slit 7 with an opening in an inner peripheral edge 5a or an outer peripheral edge 5b is formed at a part other than the discontinuous part.SELECTED DRAWING: Figure 1
【課題】建設機械の腕とアタッチメントとの間に生じる隙間を小さくするとともに、その着脱を容易なものとする建設機械のアタッチメント用シムを提供することを課題とする。【解決手段】パワーショベルやユンボ等の建設機械１の腕２にピン３を介して装着されるアタッチメント４と前記腕との間に形成される隙間Ｇにおいて前記ピンの外周に装着される弾性材料からなるシム５であって、所定幅を有し一部に不連続部Ｈを有する円環状に形成され、前記不連続部を除く部位に、内周縁５ａ若しくは外周縁５ｂに開口するスリット７が形成されていることを特徴とする。【選択図】図１
