the said rails 120 guide the chain links 130 slats 150 t profiles for example are supported by angular supporting elements 140 on the chain links 130 the chain link belt runs between the guide rollers 60 and 70 the guide roller 60 behind the public access surface in the direction of transport is connected with a driving motor via a chain or toothed wheel gear the endless mat 10 lies on the slats 150 of the belt conveyer 90 in the region of the carrying run this region serves as the public access surface 80 of the cleaning device according to the invention the load introduced by the customers and shopping trolleys moving onto the public access surface 80 is transferred from the mat 10 to the belt 90 the tracks 120 on both sides prevent slack in the chain links 130 by taking up the load and transferring it via the girders into the frame structure in order to increase the grip between the slats 150 and the mat 10 the former can be coated with an anti slip finish 50 fig4 and 5 clarify an embodiment of the support and transport system based on the flat link belt conveyor the link belt conveyor 90 consists of.
