The Evolution and Versatility of Aerial Devices and MEWPs
Discover how aerial devices, including Mobile Elevating Work Platforms (MEWPs), have revolutionised industries with their advanced designs and versatile applications. From traditional hydraulic systems to modern electric units, MEWPs like knuckle boom lifts and cherry pickers are essential tools for reaching high and hard-to-access areas. Learn how these machines have evolved to meet the demands of construction, maintenance and other critical operations.
The Role of Hydraulic Systems in Traditional Aerial Devices
Aerial devices, commonly known as Mobile Elevating Work Platforms (MEWPs), were traditionally operated by hydraulic pistons, a reliable technology that has served industries for many years. These hydraulic pistons were powered by robust diesel or petrol motors, which were strategically housed in the base unit of the machinery. This setup was particularly favoured in industries requiring heavy-duty lifting capabilities, making it a cornerstone of early MEWP design.
However, the reliance on diesel and petrol motors also meant that these early MEWPs were limited to outdoor or well-ventilated spaces, where the emissions and noise would not be an issue. Despite these limitations, hydraulic systems provided the power and control needed to operate these aerial devices efficiently, laying the foundation for future innovations.
The Rise of Electrically Powered MEWPs for Modern Applications
As technology evolved and the demand for more environmentally friendly solutions grew, lightweight electrically powered units began to gain popularity in the market. These modern MEWPs, such as those produced by Genie Lift and JLG Industries, have become particularly favoured for tasks such as window-cleaning, lighting replacement, roof inspections and other routine maintenance operations, where the need for precision and environmental considerations are paramount.
The appeal of these electric units is especially strong in indoor environments and isolated courtyards. In these settings, the use of heavier hydraulic equipment is often impractical or even impossible due to space constraints or the need to minimise noise and emissions. Electrically powered MEWPs offer a quieter, more sustainable alternative, making them an increasingly popular choice for both commercial and residential applications.
Understanding Knuckle Boom Lifts and Articulated Boom Lifts
Among the various types of aerial devices, knuckle boom lifts, also known as articulated boom lifts, stand out as some of the most versatile and commonly used in the AWP industry. These lifts, manufactured by industry leaders like Genie Lift and JLG Industries, are characterised by their distinctive shape, which includes a series of jointed sections. These joints can be expertly controlled to extend the lift in multiple directions, offering unparalleled flexibility and precision in positioning.
This design makes knuckle boom lifts ideal for accessing awkward, high-reach positions, particularly in environments where obstacles or tight spaces require a more nuanced approach. The ability to move “up and over” objects or structures is a key advantage of articulated boom lifts, making them indispensable tools in construction, maintenance, warehousing and other industries where height and reach accessibility are critical.
The Legacy and Evolution of the “Cherry Picker”
One specific type of MEWP that has become synonymous with articulated lifts is the “cherry picker.” The term originated from the device’s early use in orchards, where it was designed to help workers pick fruit high in trees, such as cherries. The cherry picker’s jointed design allowed the picker to stand safely in a transport basket, easily reaching fruit at the top of the tree without causing damage to the branches.
Over time, the term “cherry picker” has evolved into a generic term, widely used to describe any articulated lift, regardless of its application. While its agricultural roots are still recognised, today, cherry pickers are more commonly associated with a variety of industries, including construction, maintenance, mechanical engineering and utilities. This evolution reflects the versatility and enduring relevance of the cherry picker design, which continues to meet the needs of diverse industries.
Why MEWPs Are Indispensable in Various Industries
Aerial devices, including MEWPs such as knuckle boom lifts and cherry pickers, have proven to be indispensable tools across a wide range of industries. From their traditional hydraulic systems to the modern, electrically powered units, these machines offer unmatched versatility and efficiency. Their ability to operate in both indoor and outdoor environments makes them critical assets for tasks that require precision, safety and reliability.
Whether it’s in construction, where reaching high and difficult positions is essential, or in maintenance, where access to confined spaces is necessary, MEWPs provide the solutions that professionals need to get the job done. As technology continues to advance, the role of aerial devices in various industries is likely to grow even further, solidifying their place as essential equipment in the modern workplace.
