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. A handling member is connected to the second end portion of the lifting arm by means of a second rotational joint defining a third axis of rotation, which lies in a plane essentially perpendicular to the second axis of rotation, about which the handling member can pivot with respect to the lifting arm. Furthermore, the handling device includes a fork-type grab connected to the handling member and arranged so as to allow picking up; transferring and putting down such elements. |
