FIELD: metallurgy. SUBSTANCE: device for replacement of working rollers has drive trolley mounted on guides for movement along axis of rollers, drive carriage mounted on trolley for perpendicular movement relative to axis of rollers, and gripper for rollers with its drive mounted on base. Novelty is that device has auxiliary trolley mounted on auxiliary guides for movement along axis of rollers. The drive is placed under trolley and is provided with variable-length link mounted for making swinging motion. Auxiliary trolley is permanently connected to variable-length link and gripper for rollers, and periodically with main trolley by means of catch. EFFECT: simplified design of the device for replacement of working rollers, reduced metal consumption as a result of employment of combined drive for movement of trolley and grippers for rollers. 3 cl, 4 dwg
