Door safety systems
for buses and trains

Intelligent systems
for more safety

The GWU Group has been part of HÜBNER since 2019. The German-based supplier for the rail and bus industry is the leader for safety products in the area of door-closing systems and has an outstanding range of innovative solutions for the entry areas of public transport vehicles. A particular strength of the product range is its effective and consistent tolerance management which supports smooth and reliable production of the supplied components.

Hazardous situations when entering and exiting public transport vehicles

Traditional door systems in buses and trains usually cannot react adequately to spontaneous situations. Life-threatening situations can arise in connection with the doors of bus and railway vehicles when these are not equipped with safety mechanisms:

  • Passengers can be caught in the closing system and subjected to great stress
  • Children can panic if they are caught in closing doors
  • Persons and objects caught in closing doors can result in accidents and injuries

The SensIQ touchless light curtain system provides touchless anti-trap passenger protection. It detects when object or persons are in the entry area of the vehicles and prevents the doors from closing.

SensIQ signal guides passengers in out and out of the vehicle with colored LED illumination. The products lets passengers know what's happening even at a distance.

The SensIQ contact safety system is integrated into finger protection profiles. As soon as an object or a passenger comes into contact with it, a switching pulse is generated and the door opens again or is held open.
