Passively Safe Cabinet

We developed the Ritherdon Passively Safe Roadside Cabinet in collaboration with Manchester University’s School of Mechanical, Aeronautical and Civil Engineering (see MACE case study). The industry-leading design of this external enclosure extends the boundaries of passive safety and has been successfully crash-tested to the specifications outlined in European standard EN 12767.

  • The breakaway, passive safety, roadside enclosure, crash tested to EN12767.
  • Patent GB2509776
  • Occupant Safety Level = 100NE3 (EN12767:  2007).
  • Performance class, EN12767:  2019 = 100-NE-B-R-SE-SD-0.
  • Option for electrical isolation with the Poleplug, breakaway cable coupler.
  • No need for crash barriers around the cabinet.
  • Place your roadside equipment where it needs to be, rather than looking for the nearest barrier.
  • Save the cost of installing crash barriers.
  • No crash barriers means a smaller ‘target’ and greater road safety.

The EN12767 crash test required two full-scale collisions to be carried out, with a car hitting the product to measure the amount of energy it absorbed and classify it accordingly. In the first test, a 900 kg car was driven into our passively safe cabinet at 35 km/h (22 mph) to ensure the product behaved as expected. The process was repeated in a second impact test with an identical car at a much higher speed of 100 km/h (62mph).

The impact tests were conducted on a version of the Ritherdon RB800 enclosure that had been adapted for passive safety.  The crash tests were carried out by TRL at their passive safety test facility in Berkshire in early January 2013. For more information on the low-speed crash test, read the full TRL report here. Here is the report for the high-speed crash test.
