ABSTRACT:
The mobile scaffolding unit has a tower, a work platform and a service platform. The work platform can be resupplied by the service platform so as to maintain the work platform at a working elevation. The work and service platforms are located on the vertically orientated tower. Each platform is provided with electric motors to propel the platforms along the tower. The service platform is located below the work platform. The work platform has hatches in its deck for receiving cargo. The hatches are covered with doors. Cargo is located on raised platforms on the deck of the service platform. The service platform then moves up the tower to a position immediately beneath the work platform. The cargo is received by the hatches on the work platform as the service platform moves up the tower, wherein when the service platform is immediately below the work platform, the cargo is at the same level as the work platform deck. The cargo is then moved onto the work platform deck.
