The library of Amsterdam has a counterbalanced staircase as Fire Escape with a lower flight that consists of multiple parts, which are all counterbalanced. A system with magneto - electronic brakes that regulates the counterbalanced forces is incorporated in the stairs. The stairs fold away complete into the building for aesthetic reasons. In this way the building meets the safety requirements of a collective evacuation solution on every level without losing attractiveness.
For this project the architects worked closely together with the engineers of JOMY to meet the aesthetic requirements.
A fold away FIRE ESCAPE. Nobody thought it could be done... We did it!
