Zusammenfassung: | To provide a vehicle for high-place work which enables reduction of the number of components for attaching a work platform, supported so as to be swingable in a vertical direction by a parallel linkage, to a tip of a boom.SOLUTION: A vehicle for high-place work includes: a work platform 50 which is attached to a tip boom 33 forming a boom, which is provided so as to rise or fall on a vehicle body, and moved up or down by the boom; and a parallel linkage 70 provided between the tip boom 33 and the work platform 50. The parallel linkage 70 includes a boom side vertical link member 72 pivotally connected to the tip boom 33 and extending in a vertical direction. The work platform 50 is attached to a work platform side vertical link member 71 forming the parallel linkage 70, and a piston rod 37a of a leveling cylinder 37 attached to the tip boom 33 is pivotally connected to the boom side vertical link member 72 and a lower horizontal link member 74 coaxially with a pivotal connection part between the boom side vertical link member 72 and the lower horizontal link member 74.SELECTED DRAWING: Figure 5
【課題】平行リンク機構によって上下方向に揺動自在に支持された作業台を、ブームの先端部に取り付けるための部品点数を削減することができる高所作業車を提供する。【解決手段】車体上に起伏自在に設けられたブームを構成する先端ブーム33に取り付けられてブームにより昇降移動される作業台50と、先端ブーム33と作業台50との間に設けられた平行リンク機構70とを備え、平行リンク機構70は、先端ブーム33に枢結されて垂直方向に延びるブーム側垂直リンク部材72を備え、平行リンク機構70を構成する作業台側垂直リンク部材71に作業台50を取り付け、先端ブーム33に取り付けられたレベリングシリンダ37のピストンロッド37aが、ブーム側垂直リンク部材72と下水平リンク部材74との枢結部と同軸上においてブーム側垂直リンク部材72及び下水平リンク部材74に枢結される。【選択図】図5 |
