[0003] As a method of track maintenance and inspection, there is a method in which an operator walks directly on a track to an arbitrary place to perform maintenance and inspection, but as described above, since work is performed at a high place, It is extremely dangerous work. Therefore, in general, an aerial work vehicle or a tow vehicle that can position the workbench to a high place is often used.

[0004]

[Problems to be solved by the present invention] However, when using an aerial work vehicle or a wrecker vehicle, it is necessary to assemble scaffolds, install equipment, disassemble work, and carry in and out various inspection equipment near the track. It was extremely expensive and labor intensive. Further, there is also a problem that a high-altitude work vehicle and a tow vehicle cannot enter when the width of a road is narrow because the vehicle itself is large and a track inspection operation cannot be performed.
In addition, track maintenance and inspections are usually performed during periods when the monorail is not operating, so there are many midnight operations, and in conjunction with high-altitude operations, inspection work with tow trucks etc.
It was fear and mental distress for workers.

The present invention has been made in view of the above circumstances, and its purpose is to maintain a track on which a monorail vehicle runs,
It is an object of the present invention to provide a track inspection work vehicle capable of easily and safely performing an inspection.
