Abstract: A handling device for elements of tapping runners on a shaft furnace, in particular for runner covers, the device including a support base arranged on the cast house floor of a blast furnace, laterally of the tapping runner and a frame (14) which is supported by the support base and connected thereto by means of a bearing defining a first axis of rotation, which is essentially vertical and about which the frame can rotate relative to the support base. The device further includes a lifting arm having a first end portion and a second end portion, the first end portion being connected to the frame by means of at least a first rotational joint defining a second axis of rotation, which is essentially horizontal, about which the lifting arm can pivot in order to lower or lift its second end portion.

Abstract: A charging device for bulk material comprises a rotor having a substantially vertical axis of rotation a first drive for rotating the rotor and a chute supported by the rotor so as to be rotated with the latter. The chute can be rotated about its longitudinal axis. Its concavely curved sliding surface has a width that is diminishing from the top end to the bottom end of the chute, so that it is possible to vary the location where bulk material sliding down the chute channel leaves the latter by rotating the chute about its longitudinal axis.
