GRAB BUCKET AND CAPACITY CHANGING METHOD OF GRAB BUCKET
PROBLEM TO BE SOLVED: To provide a grab bucket capable of changing capacity while improving working efficiency and safety without increasing a suspension load.SOLUTION: A grab bucket includes an upper frame 1, a lower frame 2, a shell 4, a rod 5, a shell cover 6, and switching means for switching the shell cover 6 between a normal position and a capacity reduction position. The switching means includes a hinge 11 for turning the shell cover 6 to the shell 4, normal position fixing mechanisms 12, 13 and 16 for fixing the shell cover 6 in the normal position, and capacity reduction position fixing mechanisms 14, 15, 16 and 17 for fixing the shell cover 6 in the capacity reduction position. The normal position fixation is released in the state that the shell cover 6 is suspended and supported, and the shell cover 6 is turned around the hinge 11, and the shell cover 6 is fixed in the capacity reduction position.
【課題】吊荷重を増やすことなく、作業性および安全性を向上させつつ、容積を変更できるグラブバケットを提供する。【解決手段】上フレーム１と、下フレーム２と、シェル４と、ロッド５と、シェルカバー６と、シェルカバー６を通常位置と減容位置とに切り替える切替手段とを備える。切替手段は、シェル４に対しシェルカバー６を回動させる蝶番１１と、シェルカバー６を通常位置に固定する通常位置固定機構１２，１３，１６と、シェルカバー６を減容位置に固定する減容位置固定機構１４，１５，１６，１７を有する。シェルカバー６を吊支持した状態で通常位置固定を解除し、蝶番１１周りにシェルカバー６を回動させ、シェルカバー６を減容位置に固定する。【選択図】図５
