srosatsfne, I'm not trying to be mean, but have you ever tried a search engine for your questions? I highly recommend Google. Usually if you put in "manufacturer (Huss etc.) offical site" (don't include quotes), you should get the website in the results. I also highly recommend Tim Melago's Amusement Park and Roller Coaster Links, which has a multitude of manufacturers websites, including Arrow, Intamin, Vekoma, Huss, Vekoma, Zamperla etc.. It'll save you a lot of time instead of waiting for someone to reply to your question on this site.
