PROBLEM TO BE SOLVED: To provide an acceleration restricting device that reduces false feeling of an operator during restriction of acceleration.SOLUTION: An acceleration restricting device comprises: an acceleration restricting unit 16 that restricts a degree of opening of an accelerator part 11 to a predetermined restriction value or smaller in a crane work for operating a crane 2 via a hydraulic pump 12 by means of power of an engine 9 corresponding to the degree of opening of the accelerator part 11; a loudspeaker 19 that outputs sound to an operator that operates the crane 2; and a loudspeaker control unit 18 that outputs drive sound of the engine 9, recorded in advance, from the loudspeaker 19 when the degree of opening of the accelerator part 11 is restricted by the acceleration restricting unit 16.SELECTED DRAWING: Figure 3

    【課題】アクセル規制時における操作者の錯覚を抑制するアクセル規制装置を提供する。【解決手段】アクセル部11の開度に応じたエンジン9の動力により油圧ポンプ12を介してクレーン2を動作させるクレーン作業において、アクセル部11の開度を所定の規制値以下に規制するアクセル規制部16と、クレーン2を操作する操作者に対して音を出力するスピーカ19と、アクセル規制部16によりアクセル部11の開度が規制された時に、予め記録されたエンジン9の駆動音をスピーカ19から出力させるスピーカ制御部18とを備える。【選択図】 図3
