Two strong routes, depending on what the depot wants to measure.
KZV is the digital-modernization route for wheel diameter and profile workflows. Shinyei covers a broad portable inspection set from analog diameter to flange, tyre, load, tread and back-gauge measurement.
KZV SPIDER / Spider-R
Portable digital wheel-diameter measurement with electronic workflow.

Shinyei TY-50 / TY-50S
Portable analog wheel-diameter measurement.
Best for: simple, proven field measurement workflows
Shinyei TY-50D
Digital wheel-diameter measurement with electronic recording.
Best for: depots moving from analog to digital records
Shinyei TOD-500
Measure wheel-flange and tyre dimensions.
Best for: wheel-condition inspection beyond diameter
TS-3D / Back Gauge / Flange Gauge
Measure tread profile, back-to-back distance and flange dimensions.
Best for: portable wheelset inspection kits
