Help with Supermarket Shopping Cart Theft Deterrent Systems?

Jimmy asked:


The electronic locking wheel solution is an effective way to stop shopping cart loss or theft. The system works by embedding a thin wire under the concrete surface of the perimeter of the parking lot. The wheel automatically locks when it is pushed beyond the invisible barrier. The electronic wheel locking system is totally wireless reset which means the retailers does not have to bend down, lift the cart, or get their hands dirty from manually unlocking the wheels. All carts in an area can be unlocked with one touch of the button on a remote. The wheel is componentized making it easy to replace parts, reducing waste, and minimizing costs.

I am looking to install one of these systems for a local supermarket. I am having a difficult time locating a supplier that has this wire or a complete system for purchase. Any leads would be greatly appreciated.

I took it to a shop and they said it was converted to R134. I am confused can you put r134 into an r12 system, I heard you can get autozone to run a scan on it for free.Those guys I heard are awesome diagnosticians. They told me I can buy a conversion kit or something to convert it for 15 dollars and re-charge it myself with a kit for 20.00. Others on this site have seemed to have had luck with this so please help me if you can. Thank You.
