A very important part in securing bridges and tunnels for traffic control management is the (lifting) barrier. This barrier, which is designed according the European standards, assures safety under all circumstances. The reliability of the barrier is crucial. The barrier must function on very specific moments, especially when used for highways and tunnels at the moment of an incident, the barrier should function after having been idle for a long period of time. People are in immediate danger if the barrier fails.
Therefore, the design is robust and reliable and corrosion resistance is important. The number of critical parts is designed such a way that the Rusthoven barrier will function without substantial maintenance for over 20 years.
The barrier boom will break off when a car collides with it, after the collision the boom can be changed in a matter of minutes to assure the safety of the other traffic.
The frame of the barrier is made of galvanized steel, covered by a stainless-steel housing. The main parts can be accessed by two maintenance doors at the front and back side of the barrier, these can be opened with a standard key. The barriers are symmetrical and can be installed on both sides of the road.
See the specification sheet for further technical details.
For extra long lengths up to 15 mtrs, we use the RhM barrier, wich can be found on the website in the Duch map of barriers according the Dutch regulations. Beware that according the Dutch rules the maximum length is 12 mtrs. Without these requirements 15 mtr is possible. The manual is to be downloaded here.
