A cradle drive system includes a cradle drive sled. The sled includes a pin configured to mechanically couple the sled to a cradle. The cradle is configured to hold a hardware load for movement along a factory rail. The sled also includes a power interface configured to provide torque to move a hardware load. The sled further includes processing circuitry configured to, in response to determining that the sled is mechanically coupled to the cradle, transfer the cradle and hardware load longitudinally along the factory rail.
