Aerial Working Platforms Introduction
Category: Industry
2019-11-28
An aerial work platform (AWP), also known as an aerial device, elevating work platform (EWP), bucket truck or mobile elevating work platform (MEWP) 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.
Regardless of the task they are used for, aerial work platforms may provide additional features beyond transport and access, including being equipped with electrical outlets 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.
Lifting mechanisms
The most common type of aerial device are known in the AWP industry as Knuckle Boom Lifts or Articulated Boom Lifts, due to their distinctive shape, providing easy access to awkward high reach positions. There are several different brand and model variations. The Jack Boom Zebra 16 by Monitor Lifts has outriggers that deploy to stabilise the machine on unstable or steep inclines. In 2019 a new model of Knuckle Boom Lift known as the Jibbi Boom Lift by Almac Italia was released. The Jibbi Boom Lift is a compact Boom Lift which runs on distinctive tracks, as opposed to wheels on other Boom Lifts, that extend and contract giving it self-levelling capabilities and the distinct ability to be utilised on high inclines.
Another type of aerial device is a Straight Boom Lift or Telescopic Boom Lift, which as its name suggests has a boom that extends straight out for direct diagonal or vertical reach by the use of telescoping sections, letting you take full advantage of the boom length range.
A Scissor Lift is a type of platform that can usually only move vertically. The mechanism to achieve this is the use of linked, folding supports in a criss-cross "X" pattern, known as a pantograph (or scissor mechanism). The upward motion is achieved by the application of pressure to the outside of the lowest set of supports, elongating the crossing pattern, and propelling the work platform vertically. The platform may also have an extending deck to allow closer access to the work area, because of the inherent limits of vertical-only movement.
Motive mechanisms
AWPs, by their nature, are designed for temporary works and therefore frequently require transportation between sites, or simply around a single site (often as part of the same job). For this reason, they are almost all designed for easy movement and the ability to ride up and down truck ramps.
Unpowered
These usually smaller units have no motive drive and require an external force to move them. Dependent on the size and whether they are wheeled or otherwise supported, this may be possible by hand, or may require a vehicle for towing or transport. Small non-powered AWPs can be light enough to be transported in a pickup truck bed, and can usually be moved through a standard doorway.
Self-propelled
These units are able to drive themselves (on wheels or tracks) around a site (they usually require to be transported to a site, for reasons of safety and economy). In some instances, these units will be able to move whilst the job is in progress, although this is not possible on units which require secure outriggers, and therefore most common on the scissor lift types. The power can be almost any form of standard mechanical drive system, including electric or gasoline-powered, or in some cases, a hybrid (especially where it may be used both inside and outside).

Such person lifts are distinguished from telescopic handlers in that the latter is true cranes designed to deliver cargo loads such as pallets full of construction materials (rather than just a person with some tools).
Vehicle-mounted
Some units are mounted on a vehicle, usually, a truck or it can be mounted on a flat back pick up van known as a self-drive,[16] though other vehicles are possible, such as railway cars. This vehicle provides mobility, and may also help stabilize the unit — though outrigger stabilizers are still typical, especially as vehicle-mounted AWPs are amongst the largest of their kind. The vehicle may also increase functionality by serving as a mobile workshop or store.
