A support platform (100) for workers dealing with maintenance and construction of a means of transport (NT). The platform (100) comprises: a motorised carriage (1); a horizontal walkway (PDN) supported by the motorised carriage (1); and devices for lifting/lowering the walkway (PDN). The platform (100) is characterised in that the walkway (PDN) comprises a plurality of short planes (9A-9G) parallel to one another that in withdrawn position are piled one on top of the other, whereas in extended position are configured as steps, one after the other. The total surface of the extended short planes (9A-9G) substantially constitutes the walkable surface of the walkway (PDN). |
