A cherry picker is a type of aerial work platform used to lift people or equipment to elevated areas. It consists of a platform or bucket at the end of a hydraulic arm, which can extend and retract to reach different heights. Cherry pickers are commonly used in construction, maintenance, and tree trimming tasks. The name "cherry picker" originated from their initial use in harvesting cherries from tall trees. Today, these machines come in various sizes and designs, including truck-mounted and self-propelled models, making them versatile for different jobs and environments.
