Portable Laser String Line HTLS-A01 is an auxiliary tool used to detect the smoothness condition of lines.

I. Overview
      The laser chord line utilizes the three-point collinear principle, employing laser to provide a reliable long-distance reference straight line. By measuring the relative positional relationship between the rail and the laser reference line, it detects the smoothness condition of the track. It serves as an auxiliary tool for identifying track irregularities during railway construction or maintenance.
