The disclosure describes a device enabling a gate to pivot while making a vertical lifting. The device comprises a vertical member, such as a metallic post, helicoidal guides on the vertical member, displacing means fixed on the gate and associated with the helicoidal guides as well as means enabling a vertical lifting of the gate when the displacing means follow a path which is determined by the helicoidal guides, which enable the gate to pivot and to open while making said vertical lifting. This gate has as a main advantage to overcome the difficulties resulting from snow falls, and finds its main utility in the electrical substations and buildings which must often be reached in spite of adverse weather conditions.
