Device (10) for servicing several spaced tap holes (12) in a furnace wall (14), said device comprising at least one tap hole servicing machine (16, 18), and a suspended rail system (20) for moving said at least one tap hole servicing machine (16, 18) between said tap holes (12). The suspended rail system (20) comprises a main track (22) running alongside said furnace wall (14) at a certain distance therefrom, a secondary track (24) associated with each of said tap holes (12), each of said secondary tracks (24) being essentially parallel to a vertical plane containing the axis passing through its associated tap hole (12), and a switching segment (26) connecting said secondary track (24) to said main track (22). |
