They are a staple in various industries, from construction and maintenance to emergency services, enabling workers to perform their duties at elevated heights safely.
In this blog post, we will journey through time to explore the history and evolution of EWPs – from their simple beginnings to the high-tech machines we see today. We’ll delve into early instances of work at height, the invention of the EWP, the significant technological advancements that have transformed their design over the years, and what we might expect in the future.
The Early History of EWPs
The concept of working at height is a familiar one. Since time immemorial, humans have sought ways to reach higher places for various purposes, from picking fruit and building structures to creating art on high walls and ceilings.
The earliest use of elevated platforms for work can be traced back to ancient civilisations. The Egyptians, for instance, were known to use simple wooden scaffolds to build their monumental pyramids. The Greeks and Romans also used similar methods to construct grand temples and buildings.
However, the real game-changer in working at height was the invention of scaffolding. Scaffolding has been around for centuries, with early evidence found in ancient Greek frescoes dating back to the 5th century BC. These depict wooden scaffolds used for painting murals and repairing structures.
Early scaffolding was typically made from wood and rope. It was a rudimentary solution, but it provided a platform that allowed workers to reach heights that would otherwise be inaccessible. This simple yet ingenious invention was pivotal in constructing some of the world’s most iconic structures, from the Great Wall of China to the Colosseum in Rome.
Despite their utility, these early methods of working at height had significant limitations. First and foremost, they were not exceptionally safe. Falls from height were common, and there were no safety measures in place to protect workers. Secondly, these solutions were not very flexible or mobile. Once a scaffold was erected, it was difficult to move or adjust, limiting its usefulness. Lastly, the process of setting up and dismantling these structures was time-consuming and labour-intensive, which could slow down project timelines significantly.
These limitations eventually gave rise to the need for a more advanced, safer, and flexible solution for working at height – a need that the invention of the Elevated Work Platform would eventually meet.
The Invention of the EWP
The first significant step towards the invention of the Elevated Work Platform (EWP) came in 1944 with Jay Eitel’s creation of the original ‘cherry picker’ style truck and trailer-mounted platform. However, it was during the 1950s that the EWP as we know it today began to take shape. Canadian inventor Walter E. (Ted) Thornton-Trump is credited with creating the boom lift, a key component of modern EWPs.
Thornton-Trump affectionately dubbed his invention the “Giraffe,” but it would soon become more commonly known as the boom lift. His design featured a hydraulic arm mounted on a mobile platform, which could be extended to reach high places. This significantly improved over traditional scaffolding methods, offering increased mobility and flexibility.
The purpose of the EWP was simple: to provide a safe, stable, and efficient way for workers to access elevated heights. Its design was revolutionary, incorporating a platform that could be raised or lowered using mechanical means, eliminating the need for labour-intensive scaffolding erection and dismantling.
The EWP had a transformative impact on the construction industry. It offered unprecedented safety and efficiency, significantly reducing the risk of falls and the time to complete tasks at height. With the advent of the EWP, tasks that previously took days could now be completed in hours. This significantly improved productivity and allowed for more complex and ambitious construction projects.
The EWP also found applications beyond the construction industry. It became invaluable in many other sectors, including maintenance, emergency services, and film production. The flexibility and safety of the EWP made it an indispensable tool in any situation where work needed to be performed at height.
In 1973, the first JLG scissor lift was introduced, further expanding the capabilities and variety of EWPs available. This marked another milestone in the evolution of EWPs, offering a compact yet versatile solution for working at height.
The invention of the EWP marked a turning point in the history of working at height. It represented a significant leap forward in terms of safety and efficiency, and its impact continues to be felt in myriad industries today.
