An extension ladder. A ladder is a vertical or inclined set of rungs or steps commonly used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top.

It is the use of spreaders (long treads that extend well past the vertical ropes) in a pilot ladder that distinguishes it from a Jacob's ladder. When not being used, the ladder is stowed away, usually rolled up, rather than left hanging. On late 19th-century warships, this kind of ladder would replace the normal fixed ladders on deck during battle.

A Dutch sand ladder is a cable or rope ladder with rungs usually made of wood, lying on a sandy slope to allow persons to ascend or descend with minimal erosion. [1] The bottom end is anchored and the top end is designed for easy disconnection so that the ladder can be lifted up to shake loose any sand that has accumulated on the rungs. [ 1 ]
