Like most inventions, the articulated boom lift, commonly known as the cherry picker, was invented due to frustration. In Jay Eitel was picking cherries at his summer job in sunny California. He became annoyed with the inefficient process of having to climb up and down the ladder each time he moved to a new picking spot. Add to that, the safety issues of carrying a heavy basket up and down a ladder on uneven ground.

His frustration led to innovation. Mr. Eitel worked evenings and weekends to build an easily maneuverable, telescoping, steel structure mounted on a truck chassis with a simple one-lever control. By the end of World War II, he started his own company known as the Telsta Corporation and the bucket-lift became the &#;cherry picker.&#; This aerial lift design was used by the Bell Company and many other utilities and is still in use today.
In Canada, Walter E. Thornton-Trump must have been feeling the same frustrations. In he is said to have invented a boom lift to make working in high places easier. Thornton-Trump called the boom lift the &#;Giraffe;&#; it sold for $. A later model was called &#;Girette.&#; Mr. Thorton-Trump holds multiple patents related to boom lifts including:
In Pennsylvania, John L. Grove and his older brothers were building farm wagons and started Grove Manufacturing Company in . Needing a method of moving heavy steel for the wagons, John used his knowledge of hydraulics to develop a basic crane . Dealer interest in John&#;s crane soon led to the decision to produce the first mobile hydraulic industrial cranes. That decision quickly transformed the company from a manufacturer of farm implements to a world leader in the crane market. In the late s, John&#;s work with Paul K. Shockey developed an all-steel hydraulic extension ladder for use on fire trucks.
John Grove and Paul Shockey teamed up again to start Condor Industries and began manufacturing self-propelled, telescoping, hydraulic aerial lift aka a&#;cherry-picker.&#; Condor Industries was later renamed JLG Industries (John L. Grove). JLG produced products and designs which included innovations such as:
