Device for changing/transporting rolls

A device for changing a set of work rolls (7, 8, 22) in the area of a rolling stand (4) in a mill hall (1) having a roll-changing pit (10) and a side shift platform (23), where the side shift platform (23) has several track rollers (24) with which the side shift platform (23) can be moved in the direction of rolling or in the opposite direction by means of a hydraulic cylinder (28) over parallel rails (26) arranged on both sides of the roll-changing pit (10), wherein the side shift platform (23) is a simple bridge having a length substantially greater than the width of the roll-changing pit and designed to hold both a dismounted set of work rolls (7, 8) and a new set of work rolls (22) arranged side by side and parallel to one another;

• where the side shift platform (23) is designed in such a way in its length and with its track rollers (24) that, on the one hand, during the extraction of the used set of work rolls from the rolling stand (4), it bridges the roll-changing pit and is supported on the rails (26) on both sides of the roll-changing pit (10), and, on the other hand, during its lateral displacement over the roll-changing pit (10) to free the pit, it can be supported on the rails (26) only on one side of the roll-changing pit (10).
