Railway Wheel Profile Gauge


Railway Wheel Profile Gauge

The laser profilometer is employed for measuring geometrical parameters of the rail wheel flange (thickness, slope, height), rim/tire thickness and for taking full profile of the wheel roll surface.

The device is supplied with database and software package for wheel sets wear data storage and processing.
