tram front ends
As traffic volume increases, so too does the risk of accidents – particularly close to tram stops and crossings. The HÜBNER Group has more than 30 years of experience in the production of tram front ends made of polyurethane (PUR) foam. With this expertise it is possible to combine passive pedestrian protection with modern vehicle design to best effect.
Depending on the requirements, our polyurethane components can be produced so as to be robust, heat-resistant and shock-absorbent. In addition to this they have outstanding thermal and acoustic insulating characteristics.
Depending on the desired components and other customer wishes, we process PUR in the following forms:
- PUR flexible foam
- PUR integral foam - flexible to semi-rigid
- PUR integral foam - hard
- PUR compact duromer
- PUR RIM systems
Shock-absorbing front bumpers for more safety
For trams and streetcars, we produce paneling elements, head lights and special front bumpers. The "3P Front End System" (People Protection Products) for trams is made of flexible polyurethane foam and provides optimal protection for both pedestrians and the vehicle in the event of a collision.
The system consists of shock-absorbent polyurethane foam which absorbs the impact force in the case of a collision. With the use of this material, the HIC value (Head Injury Criterion) is brought substantially below the threshold value of 850.
The HIC value indicates the impact force that a person is subjected to in the event of a collision. Values up to 850 typically result in minimal or no injuries at all to the involved persons, while values over 1,300 typically result in serious injuries. Our front bumpers, vehicle paneling parts and headlights for tram vehicles have an impressive HIC value of 600. By contrast, traditional vehicle paneling parts typically have values substantially over 1,300.
