The invention relates to taphole closures for furnaces and more particularly to an automated means of presenting the taphole closure means to a furnace. Taphole closures in the form of darts with elongate tails are known, and given their weight are difficult to present to a transport arm. The object of the invention is to overcome this difficulty, an objective met by a means of loading a taphole closure means into a steelmaking vessel comprising a holder for at least one taphole closure means to hold the or each taphole closure means with an uppermost rod substantially vertical, lifting means able to engage the uppermost rod and lift the taphole closure means, control means to bring the lifting means to the taphole closure means in the holder and to cause further movement of the lifting means to bring the taphole closure means to the location of and into contact with a releaseable clamp means at the end of a transport arm, means to cause the lifting means to disengage from the uppermost rod and activate the releaseable clamp, and a means of moving the transport arm from a position of rest where it receives the taphole closure means to a position where it can be inserted into a steelmaking vessel to load the taphole closure means into the vessel.
