ABSTRACT:
A transportation system includes pallet cars coupled with one another; the pallet cars being for the positive non-slipping transportation of baggage conveyor cars for escalators. On the lower side of the pallet cars, arc-shaped drivers are pivotably mounted about one of the carrying axles constituting a pivot point, by means of a bracket. The drivers are supported on a track via a roller secured at a pivot point on the driver such that during the transportation operation the driver projects through a slot in the pallet car and engages in back of a catch which is secured at the bottom of the baggage conveyor car. Shortly before reaching the horizontal part of the transportation system the driver disengages from the catch of the baggage conveyor car.
