The Telescopic Boom Laser Screed is a specialized concrete leveling machine equipped with a hydraulic boom arm. Designed for large-scale and irregular work areas, this machine allows operators to extend the screeding head far beyond the base of the equipment, enabling precise placement of concrete even in difficult-to-access areas.
With its long horizontal reach, this boom-type laser screed is perfect for bridge decks, tunnels, wide-span industrial slabs, and other scenarios where maneuverability and range are critical. The built-in laser leveling system ensures precise slab height control, while the robust hydraulic system provides reliable performance on demanding job sites.

- Ideal for non-standard and wide-span areas
Applications of Boom Laser Screed Machine
The Boom Laser Screed Machine is suited for a wide variety of construction environments. It’s especially effective in:
- Large factory floors and warehouses
- Bridge deck concrete pouring
- Tunnel slabs
- Multi-bay industrial zones
- Pre-stressed slab foundations
For indoor or hard-to-reach areas, the Remote-Controlled Laser Screed offers unmatched flexibility.
How the Telescopic Boom Laser Screed Works
The machine uses a laser transmitter to establish a reference plane. The telescopic boom arm extends and positions the screed head above the wet concrete. Then, the following process takes place:
- The laser receiver on the screed head detects height changes.
- The hydraulic system adjusts the screed head automatically.
- Vibration and levelling blade smooths and compacts the surface.
- The operator can rotate or extend the boom to cover the next area.
This process ensures consistent results across large areas without manual measurement or adjustment.
How to Operate a Telescopic Boom Laser Screed
To use the machine effectively, follow these steps:
- Step 1: Position the machine at the edge of the pour zone.
- Step 2: Power up the laser transmitter and calibrate the system.
- Step 3: Extend the boom arm to the working position.
- Step 4: Begin leveling using the remote control interface.
- Step 5: Monitor and adjust the screed head if necessary.
- Step 6: Retract the boom, reposition, and repeat the process.
Operators should be trained briefly on the control system, which is intuitive and designed for field use.

FAQ
- What Is a Telescopic Boom Laser Screed?
It’s a boom-type laser screed with a long, extendable arm that allows the machine to reach across obstacles, rebar, or trenches without repositioning. - Where Is This Type of Screed Commonly Used?
These are often used in bridge decks, elevated slabs, or jobs with embedded equipment or post-tensioning cables. - How Long Is the Boom Arm?
The telescopic arm usually extends between 3 and 6 meters, depending on the model. It covers wide spans quickly and efficiently. - What Are the Main Benefits?
- Minimal repositioning
- Excellent reach
- Ideal for non-standard slab geometry
- Does It Require a Large Crew?
No. A boom screed typically needs one operator and one helper. The arm can be controlled either from the seat or by remote control, depending on the model.
