Abstract
Devices for lifting and lowering the driven ends of large, heavy rotating conveyor rolls and having a rigid member provided with portions engaging bearing housings journalling the driven ends of the rolls. Rotatable members, operatively connected to the rigid member, lift and lower the engaging portions in a vertical path relative to a stationary surface mounting the bearing housings so that shims supporting the conveyor rolls in a common planar position may be removed or placed therebeneath, whereby conveyor rolls in the conveying system can be removed and installed.
