In a self-propelled crane having an overwinding detection switch that is activated when the winch approaches a value exceeding a value, an overwinding stop circuit is provided that stops the drive of the winch when the overwinding detection switch is activated, and is operated when the hook is retracted. 1. A hook storage device for a self-propelled crane, characterized in that a storage switch is provided, and operation of the storage switch prohibits the operation of the overwinding stop circuit. (2) In the hook storage device for a self-propelled crane according to claim 1, the winch is driven by a hydraulic motor, and the hydraulic circuit that drives the hydraulic motor includes a relief valve that brings the hydraulic circuit into a low pressure state. , a self-propelled crane characterized in that at least one of the flow control valves is installed to limit the flow rate of the hydraulic circuit, and is operated in conjunction with the operation of the storage switch or the overwind detection switch. hook storage device. (3) In the hook storage device for a self-propelled crane according to claim 1, the winch is driven by a hydraulic motor, and a hydraulic circuit that drives the hydraulic motor includes a relief valve that brings the hydraulic circuit into a low pressure state; A flow control valve is installed to limit the flow rate of the hydraulic circuit, one of which is operated in conjunction with the operation of the storage switch, and the other is operated in conjunction with the operation of the overwind detection switch. Features a hook storage device for self-propelled cranes.
