At this time, the mobile contact network is in a non-working position state, and the freight train can perform cargo handling operation, maintenance operation and the like.

The operation method adopts the active driving mode, so that the bending point condition in the prior art can be effectively avoided, and the technical defect of arc lines in the prior art is avoided; on the other hand, each upright post in the whole mobile contact network adopts an active driving type telescopic cantilever device, so that the situation that the telescopic mechanism is not unfolded in place due to the fact that the telescopic mechanism is not pulled in the prior art is avoided.

The embodiment also provides a mobile overhead contact system, which is characterized in that at least one lifting type cantilever supporting device is adopted, and a catenary and/or a contact line are arranged on the supporting structure.

at least one moving mechanism drives the supporting structure to move upwards;

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and those skilled in the art will include within their scope variations, modifications, substitutions and alterations.
