な範囲で操作し得るように構成したことを特徴と
する直屈伸型高所作業車の安全装置。 In a direct bending and extending aerial work vehicle comprising a lower boom that can be raised and retracted freely, an atsupah boom that is pivotably supported at the tip of the lower boom so as to be able to bend and extend, and a work platform attached to the tip of the atsupah boom, the lower boom is provided with: A lower boom luffing angle detector provided on the lower boom, a lower boom telescopic length detector provided on the same lower boom, a bending/extending angle detector provided on the Atsupah boom, and an Atsupah boom telescoping length detector provided on the Atsupah boom.
The detection signal detected by the detector is input to the coordinate calculation processing means provided at the next stage, and the coordinate calculation processing means calculates the relative coordinates from the pivot foot pin of the lower boom to the end of the workbench attached to the tip of the upper boom. and inputting the relative coordinate value obtained by the coordinate calculation processing means and the detection signal detected by both the lower boom heave angle detector and the lower boom extension/contraction length detector to an area setting device provided at the next stage. Seshime,
Each of the area signals determined by the area setter is input to the next-stage existence area determination means, and the predetermined determination signals extracted by the existence area determination means are used to determine the elevation, expansion and contraction of the lower boom and the bending, expansion and contraction of the upper boom. 1. A safety device for a direct bending/extending aerial work vehicle, characterized in that the lower boom and the upper boom can be operated within a safe range by supplying the power to a predetermined control device that performs each of the following.
