PROBLEM TO BE SOLVED: To provide an inexpensive high-place work vehicle, which can be easily operated and uses a simple manual lifting mechanism instead of a battery-driven lifting means.SOLUTION: A high-place work vehicle 1 comprises a carriage 2 with braces 3 installed on its four corners, and a work bench assembly 4 supported by four inserted legs 5 that are inserted to the braces 3 on the carriage 2 so that a height position of the work bench assembly from the carriage 2 can be changed. The inserted leg 5 has a communicating hole 16, which faces a locking hole 9 of any one of the braces 3 depending on a height position relative to the brace 3. The work bench assembly 4 comprises a steering column 10, a scaffold support member 11, scaffold board 12, a handrail beam 13, an upper horizontal beam 14, and a lock mechanism 15. The lock mechanism 15 locks or releases the inserted leg 5 and the brace 3 at a desired relative height position by inserting or detaching a lock claw 41 of a lever plate 33 into or from the communicating hole 16 of the inserted leg 5 and the locking hole 9 of the brace 3.SELECTED DRAWING: Figure 1
【課題】バッテリ駆動の昇降手段を用いず、簡易な手動式の昇降機構を用い、操作が容易で、安価に得られる高所作業車を提供する。【解決手段】高所作業車１は、四隅に支柱３が立設された台車２と、この台車２の支柱３に被挿される４つの被挿脚５によって台車２に対して高さ位置を変更可能に支持される作業台組立体４とを具備する。被挿脚５は、支柱３との相対高さ位置により、支柱３のいずれかの係止孔９に対面する連通孔１６を具備する。作業台組立体４は、ステアリングコラム１０、足場支持部材１１、足場板１２、手摺ビーム１３、上部横ビーム１４、ロック機構１５を具備する。ロック機構１５は、被挿脚５の連通孔１６と支柱３の係止孔９にレバー板３３のロック爪４１を挿脱することによって、両者を所望の相対高さ位置で拘束、解放する。【選択図】図１
