6 meter electrical guide rail CADO

Despite the advantages of using hydraulics there are also some disadvantages from whom you should be aware in being responsible for highway management. Compared with electricity hydraulics are less environment friendly, they have higher maintenance costs and they are less reliable.

Therefore SPIE developed a 6 meter guide rail shaped electrically driven central median emergency access gate CADO. Same functionality but electrical powered. Recently we installed two of these at the Sluiskiltunnel in the Netherlands.
