アウトリガの安全装置。 A jackbox is pivoted so as to be swingable in the longitudinal direction of the car body via a horizontal rotation pin at the tip of an outrigger beam that extends and retracts with respect to the car body, and the jackbox is swinged and held in a vertical or horizontal position. The outrigger is equipped with a length detector that detects the extension/contraction length of the outrigger beam and a position detector that detects whether the jack box is in the vertical position, and when the outrigger beam is not extended beyond a certain length. An outrigger characterized in that the operation of swinging the jack box from a vertical position to a horizontal position is disabled, and when the jack box is not in the vertical position, the operation of reducing the outrigger beam to less than a certain length is disabled. safety equipment.
