A telescopic boom aerial work platform (straight boom type) is a heavy equipment that uses a vertically retractable multi-section boom to raise the work platform to a high altitude.

Telescopic Boom Lift is a large-scale equipment that uses a retractable straight boom structure to raise the work platform vertically to the sky. It is usually driven by diesel, electric or hybrid power, providing greater horizontal extension capacity and vertical height (about meters). Its characteristics are that the boom can be horizontally retracted and the angle can be flexibly adjusted. It is suitable for long-distance high-altitude operations across objects and is widely used in high-altitude construction and maintenance in scenes such as construction, municipal administration, and trunk lines.

A. Structural Features

· Vertical Telescopic Boom: 

Telescopic boom lift platform is composed of multiple box-type booms stacked together and extended vertically by hydraulics.

· Long-span Operation: 

The boom extends in a straight line to provide a higher vertical coverage.

· Strong Stability: 

The telescopic boom lifts are usually equipped with outriggers or counterweight systems to ensure high-altitude stability.

B. Working Principle

· Linear Telescopic: 

The hydraulic system pushes each boom to extend in sequence to reach the target height.

· Limited Rotation: 

The boom of some models can swing slightly, but the flexibility is lower than that of the crank type.

C. Typical Application Scenarios：

· Exterior wall cleaning or glass installation of high-rise buildings

· Bridge and tower crane maintenance

· Port container yard operation

D. Advantages

· Higher Operating Height: 

The telescopic boom lift can cover an altitude of more than 40 meters (some models exceed 50 meters).

· Strong Carrying Capacity: 

The telescopic lift platform has a larger load capacity, which is suitable for carrying heavy tools or multiple people.

· Intuitive Operation: 

The linear lifting control is simple, suitable for quickly reaching high-altitude points.

E. Limitations

· Low Flexibility: 

Telescopic boom aerial work platform  cannot bypass obstacles and requires a straight path.

· Large Footprint:

Telescopic boom aerial work platform  requires a large deployment space and has high site requirements.
