High speed and law cost tunnel inspection system
A lot of railway tunnel inspection should be done for only 3-4 hours between the last train and the first train. Conventional visual inspections using large high place working vehicles have limited work volume. To use TM-270, user can carry by hand on site and scan tunnel surface with high resolution to detect hair cracks. TM-270 is the inspection system for railway tunnels that greatly reduces labor and efficiency on site.
