Pressure-Neutral Swing-Sliding Door for Tunnel Cross-Passages

Railway tunnels pose a special challenge for door systems: dynamic alternating pressure loads of up to 10 kPa at several million load changes and static pressures of up to 30 kPA are requirements that door and gate systems have to withstand over a period of at least 20 years. Due to the overpressure in cross passages, the opening of swing doors is always a challenge and requires more force. In the event of an incident, it may therefore be significantly more difficult or even impossible to open the cross-passage door during an evacuation.

Pressure Differences Are Compensated without Opening Aid
