Device for parking vehicles

A device for parking a plurality of vehicles on top of one another, the device comprising:

• at least one platform,
• a lifting installation able to lift and lower the at least one platform,
• a first synchronization traction element on a first side of the at least one platform, and
• a second synchronization traction element on an opposite second side of the at least one platform, wherein the first and second synchronization traction elements are able to synchronize respective movements of the first and second sides of the platform,
• each synchronization traction element having:
• a first part in a first region of the at least one platform,
• a central, second part running along the at least one platform,
• a third part in a second region of the at least one platform opposite the first region,
• a first end fixed in the first region, and
• a second end fixed in the second region,
• wherein each synchronization traction element is guided on the at least one platform by at least one roller, and the at least one roller of the first synchronization traction elements is rotationally connected to the at least one roller of the second synchronization traction element by a synchronization shaft, and
• wherein the lifting installation comprises a piston rod supporting a deflection roller for the first or second synchronization traction element, the deflection roller being distinct from the at least one roller, and the first and second ends of the synchronization traction elements are fixed to a building which receives the device or to the device.
