scalamobil – climb stairs safely and with ease

Mobile stair climbing device for wheelchairs

scalamobil – the mobile stair climbing device for your wheelchair

Every single step is an obstacle if you are no longer able to independently climb stairs due to illness or disability – be it at home, at the doctor’s office, in public buildings or when visiting friends and relatives. The new scalamobil makes difficult routes accessible again: It doesn't matter whether stairs are steep, narrow or windy, whether they are made from wood, stone or carpeted: scalamobil easily and smoothly climbs all stairs. And it is simply and safely operated with little effort. Scalamobil can be used with some common models of folding manual wheelchairs or can be fitted with a Scalachair or Scalaport accessory.

  • scalamobil is a mobile system and can be used anywhere (patented climbing mechanism, transportable)
  • scalamobil fits to almost all manual wheelchairs (over 400 models in database)
  • Additonal safety and driving comfort thanks to ErgoBalance handles and IQ-Feature with safety sensors

”Finally, I can get out of the house again and visit my grandchild.”

Gisela Sch. from Dortmund

Intelligent, reliable and incredibly easy to use

The scalamobil has patented safety sensors and if necessary can be individually programmed to the actual conditions of your stairs. If desired, the sensors help the user and permit an even safer and more importantly very gentle process. This is particularly advantageous and not just for wheelchair drivers with back problems.

  • Scalaport X7

    When combined with scalamobil, the scalaport X7 allows many different wheelchairs to be transported up and down stairs without a bracket having to be fitted on every individual wheelchair and without the large wheelchair wheels having to be taken off. scalaport X7 is intended especially for nursing homes, transport providers and public buildings such as schools or museums. It also allows wheelchairs to be transported privately if the frame geometry of the wheelchair does not allow a standard bracket to be fitted for the scalamobil. The entire wheelchair is secured to the scalaport X7 to be transported up or down stairs. The new folding mechanism permits both stowing in small spaces and simple system transport. You will find more information in our scalaport info brochure.
