Bolt Lift
Bolt Lifts are a set of four bolts that serve as platforms in Super Mario Bros. 3. They only appear on Airships, and are usually only vertical. Like Donut Lifts, Mario and Luigi must continually jump to avoid falling. However, with each jump, the Bolt Lift moves to the right slightly, so they can be used as a transport above bottomless pits or dangerous Rocket Engines. Interestingly, bumping a Bolt Lift from below moves it to the left.
Bolt Lifts also appear in Super Mario RPG: Legend of the Seven Stars. Here they are found in the Factory, and work very much like isometric versions of their Super Mario Bros. 3 counterparts. Also, falling off of them usually results in being thrown back to the beginning of them (usually in a humorous way involving Trampolines) rather than death.
Bolt Lifts later appear in Super Mario Galaxy in the Dreadnought Galaxy. Here, they are operated by standing on the left side, so they will twist like a screw and move forward on the screw that they are on. In effect, Mario (or Luigi) will have to stay in motion to avoid falling.
