The opposite rotation of the respective first roller bearings 34 . 36 to the respective second roller bearings 35 . 37 arises from the respective stepped training of the corresponding first and second guide spaces FR1 . FR2 so that the first roller bearings 34 . 36 only at the first plant section, 30.11 . 31.11 the respective first guide surface 30.1 . 31.1 and the second roller bearings 35 . 37 only at the second plant section 30.21 . 31.21 the respective second guide surface 30.2 . 31.2 roll off or roll over.

It shows the 5 a variant of the transport pallets 3 in which is located between two adjacent joint axes GAS at the top 3.1 opposite bottom 3.2 two further rotatable roller bearings 50 . 51 on the corresponding transport pallet 3 arranged, which in the illustrated embodiment variant for vertical guidance of the transport pallets 3 between the first and second guide means 30 . 31 and one between the two roller bearings 50 . 51 provided further guide rail 52 are guided. The guide rail 52 can at the first and second guide device 30 . 31 , in particular on the underside of which, for example, forms a guide device floor, arranged, in particular screwed. In particular, the two roll layers are 40.51 for this purpose, in particular at the parallel to the transport direction A extending middle guide rail 52 and roll or roll off at this.

Different are the transport pallets 3 the embodiment of the 7 these two roller bearings 50 . 51 not on, but are with their respective bottom 3.2 directly contact-connected to a parallel to the transport direction A extending top 52.1 the guide rail 52 guided vertically.

4 shows a perspective view of an exemplary embodiment of two exempted and articulated via a chain link 4 interconnected transport pallets 3 of the transport system according to the invention 1 , In particular, the transport pallets 3 while in their respective joint section 20.1 on their respective tops 3.1 an elastic connecting portion 53 on, the respective joint section 20.1 two adjacent transport pallets 3 elastically spanned. In particular, the connecting portion 53 elastically pretensioned on the respective upper sides 3.1 two adjacent transport pallets 3 arranged, in particular riveted, be. The connecting section 53 can be made of an elastic natural and / or artificial textile fabric.

The invention has been described above by means of an embodiment. It is understood that numerous changes are possible without thereby departing from the inventive concept underlying the invention.
