trolley sticks to escalator

Could you correct the grammar and sentence? Are the words used correct?
How do the trolleys stick to the escalator in Asda supermarkets?

They are made of thin disks which fall into the grooves of the escalator (and of the security leaving the car park bit) hence the trolley sits on the axles and isn't wheel powered until it gets back to flat ground.

The grooves in the trolley wheels slide over grooves in the escalator providing a safe journey to upper floors.

Thanks

I see no problems with the grammar, but without seeing the mechanisms you refer to I'm having a very difficult time picturing this operation. "Stick" is not a good choice, but that's not a grammar issue. ) Perhaps if I were to visit an Asda Supermarket, all would be revealed.

(It's a better choice for adhesive or magnetism.)
