A self-propelled overhead track-mounted moving system includes an elongated support rail attachable to an overhead support structure, a carrier trolley mounted for undergoing movement along the support rail, an actuation unit supported on the support rail and on one side of the trolley, and a drive unit mounted on an opposite side of the trolley and coupled to the actuation unit. The support rail has a pair of top guide tracks and a bottom guide track. The trolley includes a housing having a pair of opposite lateral sides and a pair of front and rear ends. The trolley also includes front and rear pairs of roller wheels rotatably mounted to front and rear ends of an upper portion of the housing and supported upon the top guide tracks of the support rail and an object hanger attached to a lower portion of the housing and being disposed in a substantially centered position on the housing between the front and rear pairs of roller wheels to provide a substantially uniform distribution of the weight of a suspended object over all of the wheels. The drive unit includes a power source and a drive wheel coupled therewith and engaged with the bottom guide track of the support rail for drivingly causing movement of the carrier trolley therealong upon operation of the drive unit by the actuation unit.
