Abstract: The invention provides conveying apparatus consisting of a framework adapted to stand beside a vehicle and having a floor in substantial alignment with a battery support bed of the vehicle. Longitudinal track devices extend parallel to the floor on the framework and spaced from the floor to receive the battery between the floor and the track devices. A transport mechanism has drive devices coupled to the track devices for operation to move the transport mechanism longitudinally along the track devices and a coupling assembly is attached to the transport mechanism for movement with the transport mechanism and includes an upwardly biased connector adapted to releasably engage the battery so that on operation of the transport mechanism the battery may be loaded onto or unloaded from the floor.
