Telescopic booms are essential lifting machines for safe work at height.
Used on construction sites, in industrial maintenance, or for equipment installation, they provide access to elevated areas with great precision and impressive reach. Whether you are considering buying or renting a telescopic boom lift, it is essential to understand their operation, advantages, and differences compared to other types of aerial lifts.
In this article, we will answer in detail the main questions about telescopic booms.
What is a telescopic boom lift?
A telescopic boom lift is a mobile elevating platform equipped with an extendable straight boom. This boom consists of several sliding sections that extend using a powerful hydraulic system. Unlike an articulated boom lift with a boom made up of several articulated segments allowing operators to overcome obstacles, the telescopic boom lift favors a straight line and maximum reach.

These machines are ideal for:
-
the construction sector (installation of metal structures, cladding, roofing),
-
industrial maintenance (work at height in factories or warehouses),
-
public works (maintenance of infrastructure, signals, bridges),
-
the event sector (assembly of structures, lighting, and sound).
Professionals often opt for telescopic boom lift rental when they need a temporary solution, as it avoids a significant initial investment while benefiting from recent and well-maintained equipment.
What are the advantages of a telescopic boom lift?
The telescopic boom lift offers numerous advantages that explain its success in various sectors.
1. Great working height
Some models exceed 40 meters in height, making them essential for large-scale projects.
2. Exceptional horizontal reach
3. Optimal stability
4. Versatile use
5. Comfort and precision in use
How does a telescopic boom lift work?
The main controls allow the operator to:
- deploy or retract the boom,
- rotate the turret 360°,
- move the machine using its wheels or tracks,
- adjust the speed and the working height.
The combination of rotation and linear extension allows reaching otherwise inaccessible areas.

Maintaining a telescopic boom lift: what are the best practices?
-
Daily checks: check hydraulic oil levels, fuel, and battery water levels.
-
Visual inspection: inspect tires, stabilizers, and check for hydraulic leaks.
-
Lubrication: regularly grease joints and pivot points.
-
Cleaning: remove dust, debris, and grease.
-
Regulatory checks: in France a periodic general inspection (VGP) must be carried out every 6 months by an approved organization. The frequency of periodic general inspections depends on local regulations.
What are the differences between a telescopic boom lift and an articulated boom lift?
Although they are often compared, the telescopic boom lift and the articulated boom lift are designed to fulfill different needs.
Telescopic boom lift:
-
straight boom,
-
great horizontal reach,
-
ideal for open spaces,
-
designed to quickly reach great heights.
Articulated boom lift:
-
boom composed of several articulated segments
-
made to bypass obstacles (frameworks, machinery, walls),
-
more suitable for confined environments,
-
limited horizontal reach.

What is the maximum weight supported by a Haulotte telescopic boom lift?
Some models have a double load capacity, allowing for heavier operations without compromising safety.
What is the maximum height of a Haulotte telescopic boom lift?
Examples:
-
HT16 RTJ PRO : 16 meters, ideal for intermediate needs.
-
HT28 RTJ PRO : 28 meters, one of the most versatile models.
-
HT43 RTJ PRO : 43 meters, perfect for large construction sites.
Conclusion
The telescopic boom lift is the ideal equipment for carrying out safe work at height requiring a large horizontal outreach and impressive height. Rugged, stable, and easy to use, it is suitable for both construction sites and industrial maintenance.
Haulotte models stand out for their reliability, load capacity, and working heights that can exceed 40 meters. Depending on your needs, you can choose to purchase or rent a telescopic boom lift, with the latter option allowing cost reduction while accessing recent machines.
By selecting the lift that meets your requirements, you will gain efficiency, safety, and profitability on your projects.
