ABSTRACT:
A installation for transporting goods has a conveyor belt with supporting bars carried thereon transversely to the direction of movement of the conveyor belt. Two vertically spaced-apart supporting tracks are formed in each case by two supporting cables. Running rollers that are disposed at the lateral ends of the supporting bars can be moved along the two or more supporting cable pairs. The supporting cables are connected to one another by spaced-apart retaining frames, on which the supporting cables for the running rollers are fastened. At least one further supporting cable, on which the retaining frames are likewise fastened, is provided above the upper pair of supporting cables for the running rollers.
