Each type of boom lift has their own unique attributes that make
them better suited for different types of work. Do you know which one is
right for your job site?
Boom lifts (also known as mobile elevated work
platforms (MEWPs) or cherry pickers) utilize boom sections to
position workers and tools to an elevated position for temporary,
flexible access work, such as maintenance and construction tasks. This
type of equipment comes in different configurations that vary depending
on how these machines reach overhead work areas. The two most common
configurations of boom lifts are: articulated (articulating, knuckle)
and straight (telescopic, telescoping).
Both articulated and straight boom lifts can tackle tough jobs and come in a range of options:
- Engine- (diesel, gas, LP), electric- or hybrid-powered
Each have their own unique attributes that make them better suited
for different types of work. For example, a JLG telescopic boom lets you
reach farther, with more capacity, which puts you right where you need
to be as simply and efficiently as possible,
while JLG articulating boom lifts are ideal for jobs that require you to
get "up and over” objects.
So, how do you know which type of boom lift is right for your job
site? Here are some tips to help you make the choice between articulated
and straight.
Articulating Booms
The most easily recognizable type of boom lift is articulated due
to the boom’s distinctive shape. This type of lift uses multiple pivot
points (referred to as joints or knuckles) on the boom sections to
give you length and reach, allowing you up-and-over access, as well as
vertical reach. The main advantage of this design is that it lets
you achieve difficult positioning around obstacles at height.
Articulating boom lifts have less horizontal outreach than
telescopic booms, but because they can reach high and far, these
machines provide greater versatility to:
- Work in space-restricted, tight or narrow access, and/or confined work areas
- Reach up, over and/or out to access work areas
Telescoping Booms
The mast on a telescopic boom lift extends out in a straight
line, by utilizing one or more telescoping boom sections, to give
you enough vertical reach to directly access overhead job sites. This
design allows you to take full advantage of the boom’s entire range of
horizontal reach.
Because of their design, telescoping models do not offer the
up-and-over ability to access work at height. And this type of boom
lift requires more space to operate with than articulating
booms, including plenty of room around the machine’s chassis to make
turns and other movements.
But straight boom lifts can typically reach higher than
articulating boom lifts, which means these models provide both
maximum height and maximum outreach to:
- Access work from a distance, especially where the terrain or obstacles prevent close access
- Get into working position quickly
Tips for Choosing
It’s important to understand the specific work-at-height
requirements on a particular project before you specify the machines to
do the work. Here are three things to consider when choosing the right
boom lift to match your application:
1. Agility versus Versatility
a. An articulating boom would be the preferred choice
for applications that require agility to reach over or around objects,
such as chimneys, ceiling joists or roof trusses, HVAC or electrical
fixtures, the floors of a building under construction, or warehouse
shelves.
b. A telescopic boom lift would be the best choice for
applications that require the versatility to reach high, like
multi-story buildings, or to reach far out at a lower level, like under
bridges.
2. Job site Conditions
a. An articulating boom lift generally offers you a more compact
footprint and narrow operating profile, especially zero tail
swing models, which are ideal for space-restricted job sites.
b. A telescopic model is more productive on job sites with plenty of room to turn and space to reach.
3. Outreach
a. An articulated model can offer you multiple angles and reach to access overhead work.
b. A telescoping boom lift often can reach higher than an
articulating boom lift (depending on specific model and design
differences).
The best way to distinguish between these two types is
this: Telescopic models are better for getting people and materials into
place and holding them there, and articulating versions are better
suited for moving people and materials around obstacles and into
different positions with agility.

application, visit a manufacturer's website to learn more about
their articulated and telescopic boom lifts.
At a Glance: Articulated Vs. Straight Boom Lifts
- Telescopic lifts are best for getting people and materials into place and holding them there.
- Articulating booms are best for moving people and materials around obstacles and into different positions with agility.
- Three considerations to help you choose one or the
other: Agility and maneuverability versus reach and space, job
site conditions, and the work to be completed.
