ーム自動格納装置。[Scope of Claim for Utility Model Registration] A swivel base mounted on a vehicle so as to be swivel-driven and driven to swivel by a swivel control valve operated by an operating electric signal from a swivel operation signal generator, and a swivel base that is undulating. A work vehicle such as a mobile crane or an aerial work vehicle, which is equipped with a boom that is drivably mounted and that is driven to raise and lower by a hoisting control valve that is operated by an electric operation signal from a hoisting operation signal generator, An automatic boom storage device for a working vehicle configured to place and store the boom on a boom support provided on the vehicle, especially when the vehicle is traveling, comprising: a manually operable automatic storage signal generating switch;
A swing retracting position detection switch is provided which operates by detecting when the boom comes to a position directly above the boom support, and only when the swing retracting position detection switch is inactive, the automatic retracting signal generating switch operates based on the signal generated by the automatic retracting signal generating switch. A swing storage position detection switch and an automatic storage signal generation switch are associated with the operating electric circuit of the swing control valve so that the swing control valve is switched, and the automatic storage signal is generated only when the swing storage position detection switch is operated. A swing storage position detection switch and an automatic storage signal generation switch are associated in the operation electric circuit of the activation control valve so that the activation signal from the generation switch causes the activation control valve to be operated in the direction of lowering the boom. Automatic boom storage device for work vehicles.
