ABSTRACT:
A pair of socket members adapted to receive the necks of a pair of mill rolls are mounted on a wheeled carriage for pivotal movement about corresponding horizontal axes perpendicular to the roll axes. The socket opening is of larger diameter than the roll neck and is provided with circumferentially extending diametrically opposed and axially spaced apart upper and lower load bearing surfaces adapted to engage corresponding upper and lower surface portions of the roll neck. The carriage moves the socket members toward the roll necks with the socket members inclined downwardly for the roll necks to be freely received in the socket openings between the corresponding load bearing surfaces. The sockets are then pivoted upwardly for the load bearing surfaces to engage the roll necks and support the corresponding roll as a cantilever. The carriage is then driven to withdraw the rolls from the mill.
