Conveyor system for the transportation of passengers (21)/goods (22) formed by a bearing structure (1a), a loading/unloading area (1b) and a traction equipment (4a, 19, 20), which also comprises mobile platforms (3, 6, 7, 8, 16, 26) dragged by the traction equipment (4a, 19, 20), for the reception and transport of passengers (21)/goods (22) from a loading area to an unloading area. The mobile platforms (3, 6, 7, 8, 16, 26) have side walls (25) to define a compartment and prevent passengers (21)/goods (22) from interfering with the guiding device (4b) thereof in a carryway, from a loading area (1b) to an unloading area (1b), and in a return way, from an unloading area (1b) to a loading area (1b).
