業車。 A scissor link mechanism interposed between the work table 11 and the traveling table 12 is expanded and contracted by an actuator,
In an aerial work vehicle in which the work platform 11 can be moved up and down, a steady rest actuator is used to press the left and right outer scissor links 2 and 5 into contact with the left and right inner scissor links 1 and 4 at the pivot points where the scissor links intersect. An aerial work vehicle characterized in that the scissor link mechanism is provided with a steady rest actuator to prevent the scissor link mechanism from steadying when the scissor link mechanism is in an extended state.
