Aerial work platform

An aerial work platform (AWP), also an aerial device, aerial lift, boom lift, bucket truck, cherry picker, elevating work platform (EWP), mobile elevating work platform (MEWP), or scissor lift, is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height. There are various distinct types of mechanized access platforms.
They are generally used for temporary, flexible access purposes such as maintenance and construction work or by firefighters for emergency access, which distinguishes them from permanent access equipment such as elevators. They are designed to lift limited weights — usually less than a ton, although some have a higher safe working load (SWL) — distinguishing them from most types of <a href="/facts/Crane_(machine)/Q5axXY0l">cranes</a>. They are usually capable of being set up and operated by a single person.
Regardless of the task they are used for, aerial work platforms may provide additional features beyond transport and access, including being equipped with <a href="/facts/Electrical_outlets/938U5dTF">electrical outlets</a> or compressed air connectors for power tools. They may also be equipped with specialist equipment, such as carrying frames for window glass. Underbridge units are also available to lift operators down to a work area.
As the name suggests, cherry pickers were initially developed to facilitate the picking of cherries. Jay Eitel invented the device in 1944 after a frustrating day spent picking cherries using a ladder. He went on to launch the Telsta Corporation, Sunnyvale, CA in 1953 to manufacture the device. Another early cherry picker manufacturer was Stemm Brothers, Leavenworth, WA. Other uses for cherry pickers quickly evolved.
