To provide a grab bucket control device capable of shortening an overall working time required for cargo handling according to the type of a cargo.SOLUTION: There is provided a grab bucket control device that controls a grab bucket moving up and down by winding and delivery of a support wire, and opening and closing according to the relative winding amount or delivery amount of the support wire and an opening/closing wire. Moreover, the grab bucket control device comprises: a control unit which performs winding control of the support wire and winding control of the opening/closing wire; and a selection unit which selects a pattern of grabbing motion of a cargo of the grab bucket. The grabbing movement includes closing motion that closes the grab bucket, and lifting of the grab bucket. The control unit varies a length of an overlapping period (Tj) between a terminal end side period (T1e) and a starting end side period (T2f) of the closing motion.SELECTED DRAWING: Figure 5

    【課題】荷の種類に応じて荷役に要する総合的な作業時間を短くできるグラブバケットの制御装置を提供する。【解決手段】支持ワイヤの巻き取りと繰り出しによって昇降し、支持ワイヤと開閉ワイヤとの相対的な巻き取り量又は繰り出し量に応じて開閉するグラブバケットを制御する、グラブバケットの制御装置である。そして、支持ワイヤの巻き取り制御と開閉ワイヤの巻き取り制御とを行う制御部と、グラブバケットの荷の掴み上げ運動のパターンを選択する選択部とを備え、掴み上げ運動には、グラブバケットを閉じる閉運動と、グラブバケットの上昇とが含まれ、制御部は、選択部により選択されたパターンに応じて、閉運動の終端側期間(T1e)と上昇の始端側期間(T2f)との重複期間(Tj)の長さを変化させる構成とした。【選択図】図5
