Aspects of the present disclosure relate to a method, apparatus, and
system for replacing a drive
assembly in a turntable-type loading
station. The
system includes a structural column, a track formed on an upper surface of the structural column, a turntable, and a
bogie assembly removably coupled to the underside of the turntable, the
bogie assembly including a wheeled drive assembly, a swap rail attached to a radial side of the structural column, and a translating
cartridge movably attached to the swap rail in a
usable orientation. The translating
cartridge is configured to move along the radial side of the structural column via the swap rail while in the
usable orientation to an unloading position below the
bogie assembly, and to pivot from the
usable orientation to a correct functional orientation to couple with and decouple the wheeled drive assembly from the bogie assembly.
