Bolt Lift

Bolt Lifts are a set of nuts (often four of them) that are screwed onto a very long bolt. They serve as platforms in Super Mario Bros. 3. They only appear on airships, and are usually only horizontal. Like Donut Blocks, 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 Burners. 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 make an appearance in Super Mario Galaxy, and are located in Dreadnought Galaxy. Here, they are operated by standing on the left side, so that they twist like a screw and move forward on the screw that they are on. The player has to stay in motion to avoid falling.

Bolt Lifts reappear in New Super Mario Bros. Wii, and are once again present in the airship levels.

They reappear again in New Super Mario Bros. U, and act the same as in the previous games.
