Engineering Approach

Door systems are not only products. They are vehicle integration packages.

Door system selection must be evaluated together with the vehicle body structure, entrance step layout, usable opening width, handrail geometry, emergency release concept, vehicle electrical signals and final installation tolerances.

  • Door aperture and body structure evaluation
  • Passenger entrance geometry and step-area packaging
  • Mechanism layout and installation feasibility
  • Control unit and vehicle signal interface definition
  • Emergency release and safety function integration
  • Project-specific technical support for bodybuilders

System Selection

Door system selection depends on entrance width, body layout and vehicle application.

The table below provides a practical overview of typical use cases. Final selection should always be confirmed according to the vehicle project and integration requirements.

Selection Criteria Single-Leaf System Double-Leaf System Sliding Door System
Main Application Minibus, midi bus, commercial passenger vehicle and bus entrance applications Wide passenger entrance, accessible boarding and citybus-style applications Applications requiring sliding movement and compact side packaging
Door Movement Outward opening single-leaf movement Outward opening double-leaf movement Electric sliding movement
Integration Focus Door aperture, step area, mechanism support and control logic Wide entrance geometry, emergency concept, accessibility and body interface Side movement path, sealing, body clearance and sliding mechanism layout
Electrical Architecture 12V / 24V DC configuration depending on project 12V / 24V DC configuration depending on project 12V / 24V DC configuration depending on project
Typical Customer Bodybuilders, vehicle converters and special vehicle manufacturers Bus and minibus bodybuilders requiring wider passenger entrances Vehicle projects requiring alternative entrance movement and packaging
Common System Functions
