Cherry pickers

"Cherry pickers aren't actually meant for picking cherries. These machines are aerial work platforms that help people reach high places. Cherry pickers usually can't lift very heavy loads. However, they may have other features to help people do certain jobs. These extra-large machines take the place of scaffolding, which takes a long time to set up and take down and can be dangerous. Readers will learn about the different parts of a cherry picker, what jobs cherry pickers are used for, and . . . facts about cherry pickers. Full-color photographs help readers give context to the text"--Publisher.
