To provide an aerial work platform device capable of raising/lowering an arm member in the vertical direction and turning it in the lateral direction within a prescribed range while maintaining a position in the longitudinal direction of a work floor approximately constant.SOLUTION: An aerial work platform vehicle 1 includes a work floor movement adjustment mechanism including an arm following cylinder 38 and a work floor movement cylinder 63. When a lower arm 32 is raised/lowered and turned within a prescribed range, the work floor movement adjustment mechanism adjusts the movement amount of a work floor 64 with respect to a work floor base 62 in accordance with the change of the position of the work floor base 62 with respect to a vehicle body 2 to suppress the fluctuation of the position in the longitudinal direction of the work floor 64 with respect to the vehicle body 2.SELECTED DRAWING: Figure 8
【課題】作業床の前後方向の位置を略一定に保ちながら、アーム部材を所定範囲内で上下方向に起伏、及び左右方向に旋回させることが可能な高所作業装置を提供する。【解決手段】高所作業車1は、アーム追従シリンダ38と業床移動シリンダ63とにより構成される作業床移動調整機構を備える。この作業床移動調整機構は、下アーム32が所定範囲内で起伏旋回する際において、車体2に対する作業床台座62の位置の変化に応じて作業床台座62に対する作業床64の移動量を調整し、作業床64の車体2に対する前後方向の位置の変動を抑制する。【選択図】図8
