PROBLEM TO BE SOLVED: To provide an operation support device of a grab bucket type unloader capable of performing winding-down operation of a grab bucket smoothly while avoiding collision with a deck, and improving unloading efficiency.SOLUTION: During winding-down operation of a grab bucket 8, if a current position of the grab bucket 8 detected by a bucket current position detector 26 is positioned above a deck position, which is detected by a deck position detector 25, other than an upper opening, and a vertical interval between the current position of the grab bucket 8 and the deck position is equal to or less than a set interval, a winding-down stop signal 28a is output from a control device 30 to an inverter 28 of a motor 27 of a winch drum.SELECTED DRAWING: Figure 3

    【課題】甲板への衝突を回避しつつグラブバケットの巻下運転を円滑に行うことができ、荷揚げ効率向上を図り得るグラブバケット式アンローダの運転支援装置を提供する。【解決手段】グラブバケット8の巻下運転時、バケット現状位置検出器26で検出されたグラブバケット8の現状位置が甲板位置検出器25で検出された上部開口以外の甲板位置の上方にあり、且つグラブバケット8の現状位置と甲板位置との上下間隔が設定間隔以下となった場合に、制御装置30からウインチドラムのモータ27のインバータ28へ巻下停止信号28aを出力する。【選択図】図3
