Description
Aerial platform vehicle usually uses single row four point contact ball slewing bearing which is designed in compact structure. This type slewing bearing can bear axial force, Aerial platform vehicle usually uses single row four point contact ball slewing bearing which is designed in compact structure.
An aerial work platform (AWP), also known as an aerial device, elevating work platform (EWP), bucket truck, mobile elevating work platform (MEWP) or aerial lift is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height. There are distinct types of mechanized access platforms and the individual types may also be known as a "cherry picker" or "scissor lift."
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 cranes. They are usually capable of being set up and operated by a single person.
There are several distinct types of aerial work platforms, which all have specific features which make them more or less desirable for different applications. The key difference is in the drive mechanism which propels the working platform to the desired location. Most are powered by either hydraulics or possibly pneumatics. The different techniques also reflect in the pricing and availability of each type.
