Railway geometry measuring systems

KZV, s.r.o.

Our firm is committed to the development and production of comprehensive measurement and diagnostic systems and equipment for examining track geometry, wheel profiles, rail profiles, microgeometry, and track clearance.

Research and development

Because keeping in step with state-of-the-art technology is a priority, we actively participate in various research projects.

Our current projects

Among our current projects are completion of the Krab trolley for measuring rail track absolute position and supporting equipment for that trolley to measure corrugation.

We are certified in accordance with SN EN ISO 9001:2009
(Creation, development, production, and service of technical equipment for use in design and construction of railway superstructures)


We participated as exhibitors at the Innotrans 2016 exhibition.

On our website we have created a self-service technical support page where you may download the newest versions of our programs, track the history and progress of repairs, and retrieve copies of calibration certificates and device configurations.

All types of Krab equipment now support GPS technology. This is used especially for localizing geometric defects, indicating notable points in the track, etc.

We are modernizing the KRAB 8.2 evaluation software. Its new features include project support, a new system for working with tolerances, and improved GPS support with direct access to Google Earth.
