A conveyor system for serving a plurality of processing stations having a plurality of trolley carriages, an overhead main conveyor comprising a monorail track for the trolley carriages, and forming a loop having a pair of substantially parallel sides along which the processing stations are distributed, a cable or chain for propelling the trolley carriages along the track, a plurality of side conveyors coordinated with the processing stations. Each of the side conveyors comprises a loop shaped overhead monorail track, and switches for selectively connecting the side conveyors to the main conveyor, including, for each of the side conveyors, a first switch arranged in a first position to lead a trolley carriage along the main conveyor and in a second position to deviate a trolley carriage from the main conveyor to one end of a side conveyor, and a second switch for connecting the other end of the side conveyor to the same side of the main conveyor as the first switch.
