Most Overhead Traveling Crane structures are settled extensions, which means they have no moving parts and remain in one place until they come up short or are crushed. Impermanent extensions, for example, Bailey scaffolds, are intended to be amassed, and dismantled, transported to an alternate site, and re-utilized. They are imperative in military designing, and are likewise used to convey activity while an old extension is being reconstructed. Versatile scaffolds are intended to move off the beaten path of vessels or different sorts of activity, which would some way or another be excessively tall, making it impossible to fit.

overhead traveling crane spans have two levels, for example, the George Washington Bridge, interfacing New York City to Bergen County, New Jersey, USA, as the world’s busiest extension, conveying 102 million articles every year; truss work between the roadway levels gave firmness to the roadways and diminished development of the upper level when the lower level was introduced three decades after the upper level. The Overhead Traveling Crane reaches in Hong Kong have six paths on their upper decks, and on their lower decks there are two paths and a couple of tracks for MTR metro trains. Some twofold decked connects just utilize one level for road activity; the Washington Avenue Bridge in Minneapolis saves its lower level for car and light rail movement and its upper level for person on foot and bike activity (dominatingly understudies at the University of Minnesota). Moreover, in Toronto, the Prince Edward Viaduct has five paths of engine activity, bike paths, and walkways on its upper deck; and a couple of tracks for the Bloor–Danforth tram line on its lower deck. The western traverse of the San Francisco–Oakland Overhead Traveling Crane additionally has two levels.
