The lining of runners on blast furnaces is subjected to wear and the runners must therefore be repaired at regular intervals. A considerable amount of crane capacity and a casting bay of correspondingly robust construction is needed in order to transport the runner. The device according to the invention permits the runner to be transported without having to use the casting bay crane. Instead, the runner (4) is raised or lowered between the casting bay floor (2) or another level and the tapping platform (3) by means of hydraulically powered hoisting elements (5) mounted on runner support beams (7) arranged at the level of the tapping platform.
