Abstract
An adjustment and suspension system for supporting the mainshaft of a gyratory crusher within a stationary spider hub. The system includes a piston movable within the spider hub to adjust the vertical position of the mainshaft. A stop member positioned within the spider hub controls the maximum vertical movement of the piston within the spider hub. A drive assembly is used to adjust the vertical position of the stop member to limit the vertical position of the mainshaft. The mainshaft is supported by a vertical support bearing and a radial support bearing that are located separate from each other. The vertical position of the drive shaft is controlled by a supply of pressurized hydraulic fluid introduced into the spider hub to control the vertical position of the movable piston.
