Abstract

Abstract A vacuum snow remover and method for removing snow from roads and other snow covered surfaces is provided. The pneumatic snow remover assembly includes a fan for creating a suction pressure to draw snow up from the road into a collection tank via a main intake conduit. A melting chamber having heated tubes melts the snow in the collection tank. The melted snow collects in a basin below the melting chamber where it can be discharged into a sewer, open field or other area as desired via a discharge outlet. The vacuum snow remover also has an auxiliary inlet conduit which may be manually manipulated for pneumatically removing snow from curbs, sidewalks, and other places which cannot be easily reached by the main intake conduit. In the preferred embodiment, the vacuum snow remover also features at least one snow-melting conduit with an auxiliary heater that blows heated air on ice and hardened snow on and along the road to enhance snow removal.
