BOTH GRIP ATTACHMENTS MOUNTED AND USED IN POWER SHOVEL
PROBLEM TO BE SOLVED: To provide both grip attachments that are superior in durability, and furthermore can efficiently change the posture of an upper claw and a lower claw.SOLUTION: Both grip attachments have: a first support pin 51 for turnably supporting a first link 71 by a tip of a cylinder of a power shovel; a first connecting pin 61 for turnably connecting the first link 71 with an upper claw 3; a third connecting pin 63 for turnably connecting the rear end of the upper claw 3 with the rear end of a lower claw 4; a second support pin 52 for turnably supporting the lower claw 4 by a tip of an arm 2 of the power shovel; a fourth connecting pin 64 for turnably connecting the lower claw 4 with one end of a second link 72; a second connecting pin 62 for turnably connecting the other end of the second link 72 with the first link 71; a third link 73 turnably connected to one end of the second connecting pin 62; and a third support pin 53 for turnably supporting the third link 73 by the arm 2.SELECTED DRAWING: Figure 1
【課題】耐久性に優れ、しかも上爪と下爪の姿勢を効率良く変化させることが可能な両つかみアタッチメントを提供する。【解決手段】パワーショベルのシリンダーの先端部が第１リンク７１を回動可能に支持するための第１支持ピン５１と、第１リンク７１と上爪３とを回動可能に連結する第１連結ピン６１と、上爪３の後端部と下爪４の後端部とを回動可能に連結する第３連結ピン６３と、パワーショベルのアーム２の先端部が下爪４を回動可能に支持するための第２支持ピン５２と、下爪４と第２リンク７２の一端とを回動可能に連結する第４連結ピン６４と、第２リンク７２の他端と第１リンク７１とを回動可能に連結する第２連結ピン６２と、第２連結ピン６２の一端に回動可能に連結される第３リンク７３と、アーム２が第３リンク７３を回動可能に支持するための第３支持ピン５３と、を有する両つかみアタッチメント。【選択図】図１
