simeon ortmüller proposes ACCESS, an emergency river-crossing device


considering that accessibility is one of the most important factors on the scene of an accident, up-and-coming industrial designer simeon ortmüller presents ‘ACCESS’ — an emergency river-crossing bridge. not only is ACCESS easily transportable, the mechanism is practical in rural areas lacking infrastructure due to its ability to adjusts to various topographical environments, sparing any critical time that could be spent crossing the river otherwise.

ortmüller’s ACCESS is comprised of a lightweight construction where the reduced frame is made out of bent aluminium pipes, making the mechanism easy to assemble. on each side of the river, a system unit will be anchored deeply into the ground in order to achieve a safe and stable river crossing.

the static stability of the device is made possible through spanning two ropes across the river. a flexible floating jet inflates with compressed air from one of the units, allowing it to unfold and will then be locked into place by the available ropes; this creates a stream-resistant crossover and provides efficient transportation of victims.

  • Very well designed and extremely practical.
    Congratulations and success.

    Sérgio Werneck de Figueiredo says:
  • Agreed, great work!
    Do you have any beta versions, trials in use?

    ChrisRock says:
  • Thank you very much!
    Up until now it is a student concept.

    Simeon says:
  • Well thought. But you must consider that many riverbanks are very rocky, so you would need all sorts of anchoring at various distances. And a horizontal stabilization to prevent drift. You’re shure the rope puller is compulsory? I’d guess it would stretch just by the air pressure.

    Dirk says:
  • Thanks! Yes right, the topographical conditions like rocky riverbanks are a tricky factor for the anchoring. The solution are the flexible, pivoting tapes. If the ground is too rocky, the anchor-point can be moved to a better position within 90° of possible rotation. The bridge stretches itself by the air pressure, right not by the rope puller. The two spanned ropes prevent the drift of the floating body by the flow.
