A suspension conveyor installation having rollers (4) which are selectively linked to a drive chain (16) by driver elements (13). The driver elements (13) are arranged as link plates on the pins (15) of the drive chain (16) so as to be pivotable with respect to each other about vertical axes perpendicular to the drive chain (16), thereby allowing the driver elements (13) to flex when rounding sharp turns in the suspension conveyor installation. The bottom edge of each driver elements (13) has an oblique lifting ramp 18 at its leading edge, a glider surface (19) adjoining the lifting ramp (18), and a driver recess (20) adjoining the glider surface (19). In operation, drive receiving elements (11) on the rollers (4) are engaged by the drive recesses (20) on the driver elements (13) to move the rollers (4) with the drive chain (16) until the lifting ramp (18) contacts an obstacle (24) or an adjacent roller (4), at which point the driver elements (13) are lifted to disengage the rollers (4) from the drive chain (16).

[ We claim:] [1.] A suspension conveyor installation comprising roller devices (4) individually displaceable on rails of a rail system, and a drive chain (16) routed along said rail system above the rails (8), the bottom side of the drive chain (16) having driver elements (13,36) for engaging respective drive receiving elements (11) arranged on the top faces of the roller devices (4), wherein in an engaged position a driver element (13,36) engages a respective drive receiving element (11) while being disengaged from the drive receiving element (11) in a disengaged position,characterised in thatthe driver elements (13,36) are arranged as driver plates in the form of link plates mounted to the drive chain (16) such as to be collectively displaceable vertically upwards toward the drive chain (16), with the links (14) of the link plates being linked and pivotable with respect to each other about vertical axes perpendicular to the drive chain (16);the length of the driver elements (13,36), as measured in the conveying direction, exceeds the dimension of the roller devices (4) as measured in the conveying direction,the bottom edge of each driver element (13,36) comprises: an oblique lifting ramp (18,39), arranged at the leading end of the driver element (13,36) and descending against the conveying direction, for lifting the driver element (13,36) upon abutment; a glider surface (19,25,41), adjoining the lifting ramp (18,39) and extending in the conveying direction, for maintaining the driver element (13,36) lifted; and a driver recess (20,37), adjoining the glider surface (19,25,41), for receiving the drive receiving element (11) of a respective roller device (4);such that the disengaged position is established or maintained, respectively, by the lifting ramp (18,39) abutting onto an obstacle or an adjacent roller device (4), and by the glider surface (19,25,41) gliding on said obstacle or on the top end of an adjacent roller device (4).
