1. A suspension conveyor comprising:

  • two conveyor circuits (1,

         2) having pushing or pulling means circulating in opposite directions, the two conveyor circuits (1,

         2) being arranged as a conveyor circuit pair on opposite sides of an additional conveyor path (4), the conveying direction of both conveyor circuits (1,

         2) coinciding with a conveying direction of said additional conveyor path (4);

    roller devices (10) for carrying objects (a,b . . . n), said roller devices being entrained by the pushing or pulling means of the conveyor circuits (1,

         2); and

    a controllable switching means (3) arranged between the conveyor circuits (1,

         2), for transferring the objects individually from one of the conveyor circuits to the other conveyor circuit, said switching means being adapted to transfer the objects selectively from the conveyor path (4) to either of the conveyor circuits (1,

         2) and from either of the conveyor circuits (1,

         2) to the conveyor path (4);

    characterized in thatthe suspension conveyor is a sorting installation including means connected to the said switching means for sorting numerous different individually conveyed objects (a,b, . . . n) in the sorting installation;

    the conveyor circuits (1,

         2) and the additional conveyor path (4) extend within one plane;

    said additional conveyor path (4) forming part of both conveyor circuits (1,

         2) over at least an infinitesimal path portion at the place of the switching means (3) and extends over said at least infinitesimal path portion in the same direction as the conveyor circuits (1,

         2); and

    that the switching means (3) is further adapted to selectively allow the objects to travel past the switching means without leaving the respective conveyor circuit (1,

         2) in which the objects are present.
