An extractor for withdrawing or inserting the rolls of a continuous-casting machine, particularly the rolls of a curved roll-rack. The extractor is portable and carried by a crane or the like. The frame of the extractor has hooks which engage knobs on a fixed part of the casting machine to obtain a purchase. The extractor includes a carriage movably supported on the frame, and roll-handling means mounted on the carriage for connecting the extractor to the rolls to pick them up and withdraw or insert them. |
