Laser guided frog measuring system
The HMG determines the geometry of the frog in relation to a specified target profile. For this purpose an optical chord of 3 m length set by laser is used as a reference line.
+ Digital, laser guided measuring device
+ Entire evaluation and analysis of the frog
+ Target/actual comparison of the frog’s profile
In Practice
The data capture is carried out by a measuring unit with a vertical moveable roller. Because of this all influencing geometric parameters such as gradients, curves and amplitudes are considered during the measuring process. Thus offers a complete and detailed evaluation of the frog’s condition and wear.
