ABSTRACT:
A material handling apparatus includes a base, an upper structure and a bearing for supporting the upper structure on the base for rotation about an axis. The bearing transmits radial, axial and moment forces from the upper structure to the base and has a first race connected to the upper structure and a second race movable as a unit with the first race. Means are provided for removably connecting as a unit the upper structure and bearing from the base and comprises a locking member, a lug and means for receiving the lug. Either the lug or the retaining means is fixed to the second race of the bearing and extends downwardly therefrom and the other is fixed to the bed. The retaining means has a pair of retainer portions which are spaced from each other to closely receive the lug therebetween. The locking member is slidably received in an opening through the lug and is removably received in apertures in the retaining portions. Means are provided for releasably restraining the locking member from axial movement with respect to the retainer portions.
