Abstract
A mounting and handling arrangement for a hydraulic force applying system used to adjust and maintain a passline in a rolling mill stand comprises a hydraulic device having a manifold member extending through the top of a housing and connected to a piston cylinder assembly. Manifold member carries a position transducer along with its electrical components and hydraulic line connections communicating with internal passages for delivering hydraulic fluid to the piston cylinder assembly. Cradle assembly comprising a plate and brace members receive and support the hydraulic force assembly for its insertion and removal from the roll stand.
