A plurality of diverters each selectively divert at least one article moving member having a diverting member from a non-diverting path extending longitudinally along said sorter to a diverting rails in a diverting state. At least one of the diverters has a gate having a diverting surface. The gate is selectively rotatable between the diverting state and a non-diverting state about a generally horizontal axis. An actuator moves the gate between the non-diverting state and the diverting state. The actuator is an electrically operated rotary actuator that is rotatable about another generally horizontal axis of rotation.
