| This instrument can records the wheel tread profiles of wheel's inside
plane and the treads on the rails and easily fixes to both sides of wheel
when the wheel are dissembled from the truck or assembled to the rolling
stock as the reference. This allows measurement always at the same angle,
and measures the back gauge to ensures the assessment of wear of both tyres
as a set. [Features]  This instrument can easily and accurately fixes to both wheel. This instrument fixes perpendicular to the wheel to ensure correct measurement
of back gauge. The recording pen directly connected to the probe precisely reproduces
the tread profile on the recording paper to eliminate errors. The recording pen, an ordinary ball point pen is available in the market. The attached reading gauge with graduation lines allows correct assessment
of wear. |
