Frequently Asked Questions About JLG Telescopic Boom Lifts
What is a JLG telescopic boom lift?
A JLG telescopic boom lift, also known as a straight boom lift, is an aerial work platform with a single, extendable boom arm that provides direct horizontal and vertical reach. These lifts are ideal when you need to access hard-to-reach areas without obstructions, such as tall buildings, rooftops, or elevated work zones in wide-open spaces.
Where are JLG telescopic boom lifts commonly used?
JLG telescopic boom lifts are used in:
Commercial and industrial construction
Oil, gas, and utility work
Stadium and event venue maintenance
Bridge and highway repair
Steel erection and assembly
They’re perfect for projects where you need to reach far and high with minimal setup time.
What’s the difference between a telescopic and an articulating boom lift?
Telescopic boom lifts extend in a straight line, offering maximum reach and speed—best for open job sites.
Articulating boom lifts have multiple joints and are better for maneuvering around obstacles or working in tighter spaces.
If your job requires long, straight access at height, a telescopic boom lift is often the better choice.
