BISS – Standardized sliding step systems

The BISS sliding step systems combine flexibility and a clearly structured arrangement of functional components.

The drive and locking mechanism concept has proven its suitability for everyday use even under the most extreme conditions. Depending on your requirements, our sliding step systems adapt perfectly to the platform edge. BISS sliding step systems as single or double steps can be laid flat in the floor (insertion step) or integrated as built-in steps underneath the floor. They are placed underneath the solebar of the vehicle as a substructure step.
