Contact wire position measurement

Non-contact laser systems scan the height and horizontal position of up to four contact wires, with automatic corrections for the rolling motion of the carriage body, which is measured separately. The measurement can be carried out both under load (pantograph in operating position - contact pressure can be adjusted for the  different  types  of  overhead  line)  or  with  no  load.  When  the pantograph is up the Hitdetection/defects detection can also be measured.
