To provide a single rope type grab bucket capable of shortening the maximum hanging margin, closing a pair of shells firmly, and completely opening the shells to the end when releasing a loaded object.SOLUTION: In a single rope type grab bucket, a cylinder stroke of a double-acting hydraulic cylinder is shortened in order to shorten the maximum hanging margin and at least two kinds of connection bodies for connecting a rear surface of a shell with an upper frame or an intermediate movable frame are included in order to cope with the deterioration of the gripping force of the shell and the opening characteristic of the shell. First connection means functions when a pair of shells are closed. Second connection means functions when the pair of shells are opened.SELECTED DRAWING: Figure 2

    【課題】最大吊りしろの短縮化を計ると共に、一対のシェルをしっかりと閉鎖することができ、また、被荷役物の放出時には最後までシェルを開き切ることができる単索式グラブバケットを提供すること。【解決手段】単索式のグラブバケットにおいて、最大吊りしろの短縮化の為に、複動油圧シリンダのシリンダストロークを短くすると共に、シェルの掴み力とシェルの開き特性低下に対応すべく、シェルの背面と上部フレームまたは中間可動フレームとを連結する連結体を少なくも2種類備えると共に、第一の連結手段は一対のシェルが閉じるときに機能し、第二の連結手段は一対のシェルが開くときに機能する構造とする。【選択図】図2
