To provide a high-altitude workbench of a vertical elevating-type capable of preventing a workbench from shaking with respect to a truck body.SOLUTION: High-altitude workbench equipment of a vertical elevating-type comprises a frame body mounted flat on a truck bed, multiple cylindrical first struts parallelly projecting upward from the frame body, a workbench located above the frame body, multiple cylindrical second struts projecting parallelly and coaxially with each first strut upward from the workbench, both of a first and a second female screw parts formed coaxially with each other at the top edge of the first strut and at the bottom edge of the second strut, a male screw shaft with a first and a second male screw parts screwed to each the first and the second female screw part, and a driving unit, where the driving unit simultaneously rotates each male screw shaft around each shaft, moves the first and the second male screw parts in and out of the first and the second struts in the axial direction via the first and the second female screw parts, and raises/lowers the workbench with respect to the frame body by such operations.SELECTED DRAWING: Figure 1

    【課題】トラックの車体に対する作業台の揺れを防止する。【解決手段】トラックの荷台に平面的に取り付けられる枠体と、枠体から上方へ平行に突出する複数の筒状の第1支柱と、前記枠体の上方に位置する作業台と、作業台から上方へ平行に各第1支柱と同軸に突出する複数の筒状の第2支柱と、第1支柱の上端及び第2支柱の下端に互に同軸にそれぞれ形成された第1および第2雌ねじ部と、各第1および第2雌ねじ部にそれぞれ螺合する第1および第2雄ねじ部を有する雄ねじ軸と、各雄ねじ軸を軸中心に同時に回転させて第1および第2雄ねじ部を第1および第2雌ねじ部を介して第1及び第2支柱内に軸方向に出入りさせ、それによって作業台を枠体に対して昇降させる駆動ユニットを備える垂直昇降型高所作業台装置。【選択図】図1
