Description
The caliper for railway wheels profiles is used to measure wheel parameters of train and tram wheels:
Flange thickness (Sd)
Flange height (Sh)
Flange wear (qR)
Tread conicity (P%)
Characteristics
On the horizontal beam the slider indicates G parameter (flange thickness).
On the vertical beam the slider indicates H parameter (flange height).
There is a small horizontal scale to read qR factor.
Roller bracket distance can be 60 mm (tram) or 70 mm (railway).
