Recommendations

SAFENCE cable barriers are constructed to be adopted by the real life situation at hand - it is not set by the drawing design. When installing road barriers, occasionally situations arise where there is a need for a little extra consideration. We list a few specific recommendations below, but please do not hesitate to contact us should you face any further questions;

 How to connect different barrier technologies?

  • It is important to allow both barriers to live their separate lives. Barriers are apporoved separately which imply that the easiest way forward is to terminate the first barrier and start the second all according to respective specifications.

  • We recommend to allow for both barriers to run in full height parallel for at least two full post spaces, allow for them to overlap in longitudinal direction.

  • Hide the start of a barrier behind the termination of the other barrier. In a transition between two barriers it is important to have the terminating barrier next to the traffic and hide the start of the other barrier behind that one.

 

 Hazardous objects close behind the barrier.

    • When passing hazardous objects very close to the barrier it is possible to stiffen SAFENCE cable barriers over a limited distance to minimize the working width of the system.

 

 Is there a limit to a cable barrier's length between end anchors?

      • No, there is no limit to the distance between two SAFENCE end anchors. However, due to installation and maintenance reasons, we believe it to be wise to install end anchors atleast at about every 3-5 km. To our knowledge, the longest continous run of SAFENCE is 8 km between end anchors.

 

 What about installing in a radius?

      • Generally, roads allowing speeds of about 80 km/h and up suits cable barriers very well.

      • We do not recommend installation of sAFENCE in turns with a radius of less than 400 m, although there is measures to be taken if need be.

      • SAFENCE cable barriers should not be installed in depressions with a radius of less than 1 200 m.

      • Lateral movements should be executed over as long distance as possible to straighten curves and make the radii greater.
