The comb meter GU-1 and GU-2

The comb meter GU-1 and GU-2 0

The comb meter GU-1 according to TU U 33.2-23113534-001: 2006 is designed to measure and control the geometric parameters of the rolling surface of tire wheel bands: the thickness of the ridge, the height of the ridge, the rolling value, the steepness parameter of the ridge gR (identifying the dangerous shape of the ridge).


Compressor GU-1 in its design characteristics replaces all the earlier applied templates in the Russian Ministry of Railways (including absolute templates) for any operated railroad wheel profiles, as well as European profiles. Nonius system of scales allows to carry out the control of deterioration of wheel pairs on the European standards. The presence of a hard-alloy tip and hardened contacting surfaces, as well as the use of hardened stainless steels, provide an almost unlimited resource of these devices.
The construction and method for controlling the wear of the railroad wheel of the comb-measuring device are protected by patents.
