Sliding steps for rail vehicles - lifting axle ZH90

A sliding step extends and retracts over a million times during its lifespan. In wind, ice, and snow. At every single stop. With every passenger boarding. For it to function reliably for decades, every screw must be perfectly aligned during installation. Inside, outside, on the drive mechanism, and on the sensors. Several meters wide, complex geometry, numerous connection points.

We've rethought the process. A mounting fixture that guides two ZH90 lifting axes in precise, parallel synchronization. Supplemented by a continuously swiveling fixture in between.

Specifically, this means:

✅ The sliding step is clamped in place once and follows the worker, not the other way around.

✅ Every mounting point is accessible at an ergonomic height, from the drive and locking mechanism to the sensors and switching strips.

✅ Both axles move synchronously without tilting and ensure parallel load guidance even with wide steps.

✅ Reproducible processes, consistent torques and less scrap

✅ Stroke, intake and swivel range are individually tailored to the respective component

✅ Designed for typical sliding step platforms on the market

Bonus:

The same system architecture works wherever large and complex components need to be assembled ergonomically and reproducibly. Its applications extend far beyond railway technology.
