Need the Trade Name for this engineering product that looks & works like inverted Roller coaster car?

I need a track %26amp; car combo...dimensions like Toy roller-coaster car.. something to be used for Assembly line. The tracks are only horizontal, so no Gravity. Horizontal %26amp; curved motions with powered rail/ car. This link gives you an idea http://www.coasterdynamix.com/storeitem.aspx?item=12


but ...like to remind you again..the car travels only horizontal on the track, hanging. Those who can design %26amp; deliver also welcome to reply. The pay-load will be just 400 - 600 grams.Need the Trade Name for this engineering product that looks %26amp; works like inverted Roller coaster car?
Did you sneek a little spam in here?





PS Gravity even affects horizontal moving items.





And if you need engineering services to design one of these and you have a good idea what you want I am sure the company I work for can help. Send me a note and I will give you my email address and we can go from there.
