I think its the first to use their "enclosed cabling system." I don't know for sure, but I don't think any other tower rides, drop tower or tower swings, have used an enclosed cabling system. If you look at towers like Intamin Drop Towers or Windseeker the lift cables are exposed to the weather which I think has a lot to do with the amount of grease on the ground on and around "Drop Tower," its also starting to show on Windseeker some. You'll notice no grease stains on the ground around Mach Tower. I could be totally off the mark here, but I think thats b/c Mach's cables are in that steel channel; that and Busch probably would power wash any grease on the ground.
