Example of a railtrack

In rail applications, Z+F 2D laser scanners are not only used for rail track surveying but also for capturing objects alongside the track like buildings, tunnels, bridges or other objects which might cause a potential danger for rail traffic.

The high resolution surveying of objects like station platforms or tunnels is necessary for clearance analysis or analysing tunnel walls. When carrying oversized loads a preflight can be performed to detect narrow points.

Due to the high measurement rate and the high rotation speed Z+F measurement systems are highly suitable for rail applications. Therefore, very short distances between profiles can be realised. The Z+F PROFILER® 9012’s rotation speed for example is 200 rps.

For special requirements Zoller + Fröhlich always offers customized solutions like the Z+F PROFILER® 6007 duo.
