What was the mekhane used for in Greek plays?

In Greek plays, the mekhane was a crane-like device used to lift actors or props into the air, typically representing gods or supernatural beings descending from the heavens. This theatrical mechanism allowed for dramatic entrances and exits, enhancing the storytelling by visually depicting divine intervention. The term "mekhane" is often associated with the phrase "deus ex machina," referring to a plot device where an unexpected power resolves a seemingly insurmountable problem.
