I appreciate the request, but the context provided only contains an image caption ("thumb|upright|Extension ladder") without substantive information about what a ladder is or why it matters. I cannot write an accurate overview based solely on this caption, as doing so would require me to invent facts beyond what's stated in the provided context.

thumb|upright|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 flexible ladders, such as those made of rope or wire rope, that may be hung from the top.
