ABSTRACT:
An apparatus, such as a crane, having a bearing for rotatably connecting two structures and transmitting radial, axial, rotational and moment forces from one to the other. The bearing is separably mounted to one of the structures by threaded fasteners, e.g., bolts, having piston means associated with the fasteners with the hydraulic system being pressurized during operation to establish proper uniform preloading of the fasteners for transmitting the load forces from one structure to the other.
