Update #2!

Now, Jeanine from Chippy-Shabby

has checked in, read below!

The basket is pulled up to the trolley by a woven cotton rope ... When the basket reaches the trolley, it attaches by four little fingers that twist into a bracket. When all is secured (all automatic), one gives a good strong twitch/pull on the same rope just used and the basket and trolley (cast and polished aluminium .. with two 4" diameter wheels ..) are slung up the wire to the central cashier and wrapping desk. While the change is being made, another clerk would wrap the goods."
I have not seen this system in the UK.

Thanks Jeanine and Debra!
