FIELD: metallurgy.
SUBSTANCE: device contains annular hydraulic module piston/cylinder, installed on cylindrical section of roll neck. One end of cylindrical section is restricted by collar located on roll neck and opposite end is restricted by annular groove located on roll neck. Closing ring contains latching linkages, pivotally fixed in matching sites in groove. Holding of locking levers without additional facilities such as protective shrouds, or without increasing of clearances between levers and axis of suspension bracket it provided ensured by block piston/cylinder is implemented with mentioned locking levers with that to replace mentioned bearing to specified neck of roll and in the second mode of contact condition with mentioned projection with that to remove mentioned bearing from mentioned neck of roll. Block piston/cylinder and mentioned locking levers are outfitted by corresponding conical surfaces, operating for moving of locking levers inside into its matching sites after contact of mentioned block piston/cylinder with mentioned locking levers.
EFFECT: effectiveness increase of holding facilities of locking levers in its closed position.
