Aerial Work Platforms
Aerial work platforms or AWPs are engineered and designed to raise workers and their tools to a certain height in order to finish a job. The particular model and manufacturer and kind of equipment all varies. Before aerial work platforms were made, all jobs requiring work at high levels had to be carried out with scaffolding. Therefore, the invention of aerial work platforms has increased the overall productivity of similar jobs and kept numerous workers safe.
There are 3 main kinds of aerial work platforms. They are scissor lifts, boomlifts and mechanical lifts. These kinds of machines can be operated with pneumatics, mechanically via a rack and pinion system or with screws or by hydraulics. These units may be self-propelled with controls situated at the platform, they may be unpowered units which require an external force to move them or be mounted to a vehicle so as to be transported.
The aerial work platform was created by John L. Grove, an American inventor and industrialist. However, during 1966, before the first unit of JLG, a company known as Selma Manlift launched an aerial lift model.
John L. Grove along with his wife decided to take a road trip in 1967. This was after selling his previous company Grove Manufacturing. They decided to stop at Hoover Dam. While the couple was there, Grove unfortunately saw 2 workers electrocuted while they were working on scaffolding. This terrible incident led John Grove to discover an untapped market for a new product that could safely raise employees in the air for them to do maintenance and construction tasks in a better way.
John bought a small metal fabrication company and formed a partnership together with 2 friends, once he returned home from his trip. The small business soon began designing ideas for the aerial work platform. The new business was named JLG Industries Inc. They proudly released their first aerial work platform during the year 1920 with the aid of 20 employees.
