ATTACHING-DETACHING DEVICE OF SUSPENSION TYPE WORK ATTACHMENT

摘要

PROBLEM TO BE SOLVED: To easily attach-detach a suspension type work attachment to an arm tip part of a civil engineering machine. SOLUTION: A rockingly connected claw support member 11 is arranged in the arm tip part of the civil engineering machine. An upper part of a fixing claw 12 and an upper part of a pressing-down claw 13 are rotatably connected to the claw support member 11 at a proper interval in a state of crossing a fixing side hook 12b formed in a lower part of the fixing claw 12 with a pressing-down side hook 13b formed in a lower part of the pressing-down claw 13. When substantially maximally expending a cylinder 19 interposed between the fixing claw 12 and the pressing-down claw 13, a pin 21 installed in the suspension type work attachment is gripped and held by the fixing side hook 12b and the pressing-down side hook 13b.
