。 A first rotating table that can be rotated horizontally at the rear of the vehicle body and a main base that can be extended and retracted in the vertical direction from above the first rotating table are provided, and the base end of a boom that extends in the horizontal direction is fixed to the tip of this main base. A base column is provided at the rotating tip of the boom, and the base column is suspended via a second rotation table that is horizontally rotatable, and a first parallel link that is adjustable in hanging angle is provided on this base column via a first undulation cylinder. At the same time, a support arm whose hanging angle can be adjusted is connected to the tip of the first parallel link via a second undulating cylinder, and a boom cylinder that is approximately parallel to this support arm is connected to the tip of the support arm. A telescopic boom is installed that can rotate in a vertical plane using the leading end as a rotational fulcrum, and the leading end of the boom cylinder is connected to the base end of the telescopic boom so that the support arm and the boom cylinder form a second parallel link. A bridge inspection vehicle characterized in that the first parallel link and the second parallel link are configured to be expandable downward from the tip of the boom, and a work platform is attached to the tip of the telescoping boom.
