You're already on the edge of the code with this one. You describe the equipment as permanently installed. Under those circumstances you normally could not use flexible cords. You might use the condition "400.7 (6) Connection of utilization equipment to facilitate frequent interchange" to permit the use of flexible cords. The code already foresees the cord damage and risk you are considering and expects permanent building wiring. If you're going with flexible cords I wouldn't use the term permanently installed.
There are PVC ramp type cable covers such as Hubbell's FloorTrak products and similar metal wireways such as Hubbell's TredTrak and I believe Wiremold makes a similar product. These however are still a trip hazard and do not accommodate shopping carts and carriages very well. I would recommend overhead drops from the ceiling or floor to ceiling service poles. There are also some under carpet wiring systems available which use ribbon cable. I don't have brand names, but an electrical contractor should help.

No new electrical wiring or outlets may be added to the building, and no modifications are allowed to the floor (channels, etc.). The only option is to use an existing electrical outlet, but access to the nearest outlet requires the flexible cord to be rounted across the aisle under the foot traffic of shoppers. The cord must be protected from damage from foot traffic and that protection must not create a trip hazard. The finished installation must comply with local codes and not create potential liability issues. Given the constraints, what protection options are available on the commercial market in North America and the EU?
