作業装置は既に公知であり、かかる高所作業装置
は前記起伏シリンダー５８を伸縮する事によりリ
ンク機構５５が上下に回動し、作業台５３を昇降
する事が出来る。 Conventionally, as shown in FIG. 1, the upper end of a vertical shaft 52 extends vertically upward from the upper surface of one side of a base 51 having movable wheels, and the vertical shaft 52 of a workbench 53 extends downward from the lower surface of the other side. A link mechanism 55 is formed by rotatably supporting two parallel linear shafts 56 and 57 between the lower ends of a fixed shaft 54, and a link mechanism 55 is formed between the lower linear shaft 56 of the link mechanism 55 and the base 51. A high-altitude working device in which a hoisting cylinder 58 is rotatably attached is already known, and in such a high-place working device, by extending and contracting the hoisting cylinder 58, the link mechanism 55 rotates up and down, and the work platform 53 is raised and lowered. I can do things.
かかる装置にあつては、作業台５３の昇降高さ

５３の固定と強度性を維持が困難になると共に、
該高所作業装置を移動する際の安全性にも問題を
有していた。 In such a device, if the length of the link mechanism 55 is increased in order to increase the vertical height of the workbench 53, when the undulating cylinder 58 is reduced and the workbench 53 is stored on the base 51, The fixed shaft 54 extending from the lower end of the workbench 53 protrudes outward from the side end of the base 51, making it difficult to maintain the fixation and strength of the workbench 53 during storage.
There was also a problem with safety when moving the high-altitude work equipment.
この為かかる機構の高所作業装置においては、
リンク機構５５の長さに一定の制限が存在し、前

かつた。 For this reason, in high-place work equipment with such a mechanism,
There is a certain limit on the length of the link mechanism 55, making it impossible to increase the height of the workbench 53.
本考案はかかる従来技術の欠点に鑑み、作業台
や該作業台を昇降させる各種部材が基台上よりは
み出す事なく、コンパクトに収納可能に構成した
高所作業装置を提供する事を第１の目的とする。 In view of the shortcomings of the prior art, the first object of the present invention is to provide an apparatus for working at high places in which a workbench and various members for raising and lowering the workbench do not protrude above the base and can be stored compactly. purpose.
第２の目的とする所は、前記作業台を２段状の
リンク機構に連結する事により作業台の昇降高さ
を大に設定しつつ、該作業台がほぼ垂直に昇降可
