Zusammenfassung: | The present invention relates to a gate with an emergency opening device, comprising a gate panel which is movable between an open and a closed position, a primary motor which drives the gate panel by way of a gate panel drive, and an auxiliary motor which is connected to an emergency power supply and is adapted to drive the gate panel. In order to improve such a gate to the extent that the emergency opening device is reliably usable to open the gate in the event of different types of failure of the main drive motor of the gate, it is proposed that the auxiliary motor be coupled by way of an auxiliary motor coupling to the gate panel and that the emergency power supply comprise an energy storage. |
