Abstract: An aerial transportation installation is provided with a carrier vehicle and a terminal. The terminal comprises a moving device to move the carrier vehicle in the terminal. The moving device defines a running path of the carrier vehicle and moves the vehicle. A platform is arranged on one side of the running path. The platform allows movement alongside the moving device and enables an operation to be performed on the moving device. The terminal defines a running space for a grip of the carrier vehicle. The moving device is arranged between the platform and the running space. An additional platform is movable between first and second positions. In a first position, the additional platform does not form an obstacle to progression of the vehicle. The second position enables maintenance to be performed on the moving device.
