PROBLEM TO BE SOLVED: To provide a grapple for a hydraulic shovel which prevents a cover protecting hydraulic equipment in a claw-type frame from dropping out.SOLUTION: One end of a cover 20 protecting a hydraulic mechanism 14 in a claw-type frame 12 of a grapple 10 for a hydraulic shovel is inserted into an insertion portion 18 provided in a pedestal 16 mounted on the claw-type frame 12 and the other end thereof is mounted on a mounting surface 17 of the pedestal 16 via a movable connection mechanism 19. The movable connection mechanism 19 has: a pedestal-side boss 22, protrudingly provided on the mounting surface 17, whose height His higher than a thickness T of the cover 20; a through-hole 23, formed in the cover 20, through which is inserted the pedestal-side boss 22; male screw means 24, tip side of which is screwed into a female screw part 21 of the pedestal-side boss 22 and whose head part diameter is larger than an inner diameter Dof the through-hole 23; and a cylinder member 25, erected on the surface of the cover 20 concentrically to the through-hole 23, whose inner diameter Dis larger than a head part of the male screw means 24 and whose height His higher than a height position of the head part of the male screw means 24 fastened to the pedestal-side boss 22 which protrudes from the through-hole 23.SELECTED DRAWING: Figure 3
【課題】爪フレーム内の油圧機器を保護する蓋の脱落を防止した油圧ショベル用グラップルを提供する。【解決手段】油圧ショベル用グラップル１０の爪フレーム１２内の油圧機構１４を保護する蓋２０は、一端側が爪フレーム１２に取付けた台座１６に設けた挿入部１８に差し込まれ、他端側が台座１６の取付け面１７に可動連結機構１９を介して取付けられ、可動連結機構１９は、取付け面１７に突設され、高さＨ１が蓋２０の厚さＴより大きな台座側ボス２２と、蓋２０に形成され、台座側ボス２２が挿通される貫通孔２３と、台座側ボス２２の雌ねじ部２１に先側がねじ込まれ、頭部の外径が貫通孔２３の内径Ｄ１より大きな雄ねじ手段２４と、蓋２０の表面に貫通孔２３と同心状に立設され、内径Ｄ２が、雄ねじ手段２４の頭部より大きく、高さＨ２が、貫通孔２３から突出する台座側ボス２２に締め付けられた雄ねじ手段２４の頭部の高さ位置より高い円筒部材２５とを有する。【選択図】図３
