Abstract

A method and installation is disclosed for the replacement of a bottom closure of a track-mounted pugh-type transfer ladle having a transfer container supported by two longitudinally spaced-apart bogies which are pivotally attached to the transfer container for swinging movement about a vertical axis, the transfer container having a removable bottom closure located between said bogies. The ladle is moved longitudinally of itself and the two bogies are directed on to different tracks which are spaced from each other to thereby swing the bogies relative to the transfer container and increase the longitudinal space between the bogies; and thereafter the closure is replaced from below through the resulting increased space.
