GRIP ATTACHMENT FITTING STRUCTURE OF BACKHOE
PROBLEM TO BE SOLVED: To provide a grip attachment fitting structure of a backhoe capable of easily and safely executing attaching-detaching work of a grip attachment of the backhoe.SOLUTION: A bearing cylindrical body 16 of a substantially cylindrical shape of penetrating a bearing hole 16a into a central part, is fixed to an arm 2 of a backhoe so that both end surfaces respectively project from left-right side surfaces of the arm, and a circular arc-shaped engaging part 21 of opposing an inner peripheral surface to a part of an outer peripheral surface of the bearing cylindrical body 16, is provided around respective shaft holes 11b of an opposed surface of a pair of left-right grip forks 11a for constituting a grip attachment 11. The grip attachment 11 is rotatably connected to the arm 2 by inserting a connection shaft 12 into the respective shaft holes 11b and the bearing hole 16a, and in a state of extracting the connection shaft 12 from these shaft holes 11b and the bearing hole 16a, the respective engaging parts 21 engage with both-end part outer peripheral surfaces of the bearing cylindrical body 16, and check falling of the grip attachment 11.SELECTED DRAWING: Figure 5
【課題】バックホウの掴みアタッチメントの着脱作業を容易且つ安全に行うことのできる、バックホウの掴みアタッチメント取付構造を提供する。【解決手段】バックホウのアーム２に、中心部に軸受孔１６ａが貫通した略円筒状の軸受筒体１６が両端面が当該アームの左右の側面からそれぞれ突出するように固定され、掴みアタッチメント１１を構成する左右一対の掴みフォーク１１ａの対向面のそれぞれの軸孔１１ｂの周囲に、軸受筒体１６の外周面の一部と内周面が対向する円弧状の係合部２１が設けられている。掴みアタッチメント１１は、それぞれの軸孔１１ｂと軸受孔１６ａに連結軸１２を挿入することにより、アーム２に回動自在に連結され、これらの軸孔１１ｂと軸受孔１６ａから連結軸１２が引き抜かれた状態では、それぞれの係合部２１が軸受筒体１６の両端部外周面に係合して掴みアタッチメント１１の落下を阻止する。【選択図】図５
