ーンのジブ格納装置。 The base end 8a of the jib 8 is connected to the distal end 13b of the boom 4, which is installed on the vehicle 1 so as to be movable up and down, in a vertically rotatable and removable manner. In a vehicle-mounted crane mounted so that it can be swung forward from a folded lower holding position through the lower part of the boom, the jib 8 provided between the boom 4 and the jib 8 and in the lower holding position is supported by the boom 4. Jib support means 20, and jib lower position positioning stop means 40, which is located on the boom 4 side and stops the jib 8 at a position where it can be supported by the jib support means 20 when the jib 8 is folded to the lower position.
, a jib lifting means 50 which is located on the boom 4 side and which raises the jib 8 supported in the lower position by the jib support means 20 to a position along one side of the boom 4; A jib side-holding position localization stopping means 60 stops the jib 8 pulled up to the side of the boom by the jib lifting means 50 at a side-holding position on the side of the boom; The jib supporting means 20 is provided with jib side-holding fixing means 70A and 70B for fixing the jib 8 stopped at the side-carrying position in the side-carrying position. a jib holding member 21 that is attached via a shaft 22 installed parallel to the axis of the jib 8 in the lower holding position and that can be raised and lowered around the shaft 22 over an approximately 90° angle; In the collapsed state, a position closer to the base end of the jib 8 than the center of gravity G in the lower holding position is connected to the jib 8 so as to be swingable in the vertical direction via a connecting shaft 31 that is perpendicular to the horizontal direction with respect to the axis of the jib 8. In addition, the connection device 30 that can be disconnected and the jib 8 in the lower holding position are allowed to rotate slightly around the connection shaft 31 of the connection device 30 due to the weight of the jib 8, and then the rotation is restricted. Stopper device 3
4. A jib storage device for a vehicle-mounted crane, comprising:
