GEDO Doc System - Track Quality Control

The Trimble GEDO Doc system consists of the Trimble GEDO CE 2.0 track measurement trolley, the Trimble GEDO Profiler or Trimble total station and a Trimble control unit.

The system enables simple track geometry control by measuring basic quality parameters. Cant (superelevation), track gauge and twist are recorded as a function of the chainage. Measured values are shown directly in the field via live display. Important positions can be captured and coded quickly.

With the Trimble GEDO Profiler, the distance and height to control points can be measured, and distances to platform edges or other objects near the track can be checked.

Capture of track gauge, cant (superelevation), and twist as a function of the chainage
Live display of current values
As-built check with known reference points
Log file can be output directly in the field

Trimble GEDO Profiler

Laser measuring unit for checking track position at control points, as well as for measuring distances to objects close to the track (i.e. structures and platforms). Distances are displayed in relation to the track axis or inner edge of the rail, both perpendicularly and vertically to the cant (superelevation).

Alternatively, a Trimble total station can also be used.
