YG Machinery

Traditional manual screeding and vibratory beam leveling methods for concrete floors generally suffer from poor precision, low efficiency, high reliance on manual labor, and numerous joints in large-area floor construction. They struggle to meet the high-standard flooring requirements of ultra-large factories and logistics warehouses. Telescopic boom laser screeds, also known as boom laser screeds, laser leveling machines, or boom laser pavers, are automated floor leveling equipment with a built-in telescopic robotic arm and laser control system. They are core machinery for large-scale concrete floor construction.

Compared to ordinary walk-behind laser screeds, the biggest difference in telescopic boom models is the presence of a telescopic robotic arm—the leveling head is attached to the front of the arm. The machine itself can remain stationary, relying on the telescopic arm to cover a larger working area. This reduces the need for frequent machine movement, minimizing compaction of the poured concrete, improving construction continuity, and increasing efficiency. YG’s main model is the telescopic boom version, but they also offer more affordable models without a telescopic boom (two-wheeled walk-behind/four-wheeled ride-on) to meet the needs of customers with different budgets and project sizes. This concrete laser screed machine has been exported in bulk to countries including the United States, Germany, Australia, the United Arab Emirates, Mexico, and Poland, and is widely applicable to various flooring construction scenarios such as industrial plants, logistics warehouses, and municipal engineering projects.

What Are the Components of a YG Telescopic Boom Laser Screed?

• Telescopic Boom System: The core structure of the equipment, typically consisting of 2-3 boom sections. The YG model has a boom length of approximately 6 meters. The boom is welded from high-strength steel plates and integrates hydraulic cylinders and pipes for forward and backward extension. The screed head is attached to the front end of the boom, allowing it to swing left and right and float up and down.
• Screed Head Assembly: The working device that directly contacts the concrete, including an auger, a vibratory screed, and a compaction beam. The auger levels the concrete to the set elevation, while the vibratory screed performs high-frequency compaction to ensure the concrete is dense. The screed head width is typically 3-3.5 meters.
• Laser Control System: The “brain” of the screed and elevation control. It consists of a laser transmitter (Trimble or MOBA brand) on the ground and a laser receiver on the machine body. After receiving the laser plane signal, the receiver automatically adjusts the screed head height via the hydraulic system, achieving automatic leveling. Accuracy can reach ±2mm/3m.
• Chassis and Walking System: The foundation supporting the entire machine. Available in two-wheel and four-wheel chassis, with high-end models supporting two-wheel steering, four-wheel steering, and crab steering modes. Tires are non-slip solid tires, resistant to punctures from sharp objects on construction sites.
• Power System: Generally powered by a diesel engine. The YG uses a Yanmar 4TNV94L engine with a power output of 35.5kW (48 hp). The engine drives a hydraulic pump, providing hydraulic power for all machine movements.
• Hydraulic System: Boom extension and retraction, leveling head lifting, vibration, and walking are all hydraulically driven. A load-sensitive hydraulic system ensures precise and rapid response. The hydraulic oil tank has approximately 150 liters, ensuring stable oil temperature during extended operation.
• Driving and Control System: The operator sits in the driver’s seat and controls the equipment via a joystick and touchscreen. A color display shows equipment status, fault diagnosis, elevation settings, and other information. Some models support remote control operation.

What Are the Core Features of the YG Telescopic Boom Laser Screed?

1. Imported laser system with ±2mm high precision. Utilizing either the American Trimble or German MOBA laser systems, industry-recognized top brands. The laser emitter establishes a reference laser plane on the ground, while the receiver on the machine detects the height signal in real time, automatically adjusting the screed head’s lifting and lowering. The screed leveling error is controlled within ±2mm/3m. FF flatness can reach over 50, far exceeding the precision of manual screeding.
2. 6-meter telescopic boom for a large coverage area. The main boom can be fully extended to 6 meters, and with the screed head’s left and right swing, a single coverage width exceeds 3.5 meters. A single extension and retraction covers tens of square meters, significantly reducing movement time and increasing construction efficiency by 2-3 times compared to hand-held machines. It can also be used in dense column grids; simply extend the boom between columns.
3. Three steering modes for flexible adaptation to various sites. The high-end model supports free switching between two-wheel steering, four-wheel steering, and crab steering modes. Two-wheel steering allows for quick site relocation; four-wheel steering offers a small turning radius, making it flexible in confined spaces; crab-like steering allows for sideways movement, facilitating edge and wall-mounted construction.
4. Integrated construction: leveling, vibration, and slurry raising in one step. The spiral concrete spreader scrapes the concrete to the designated elevation + high-frequency vibration by the vibrating plate + slurry raising by the scraper—three processes completed in one go. No need for manual spreading, vibration, and leveling, saving several steps and labor. The finished surface has uniform density and is less prone to sand and dust.
5. One-button automatic leveling legs for immediate operation upon site change. All four legs automatically level with a single button press, regardless of the ground’s surface level. Changing sites or positions takes only minutes, eliminating the need for manual leveling.
6. Solid puncture-resistant tires for unrestricted movement on construction sites. Solid rubber tires are resistant to punctures from rebar, broken glass, and sharp stones. No need to inflate, no risk of blowouts, can be built anywhere on construction sites, reducing the hassle of work stoppages for tire changes.

Case Study: YG Telescopic Laser Screed Machine Used in an Industrial Plant Project in Riyadh, Saudi Arabia

Client Background: A construction company in Riyadh, Saudi Arabia, undertaking industrial and commercial building projects. Saudi Arabia has many infrastructure projects, but the high temperatures and dry climate make concrete construction challenging.

Problems Encountered: High local temperatures cause concrete to set quickly, making manual leveling slow and inconsistent, compromising quality. Furthermore, local labor is expensive and difficult to manage.

Solution: In 2024, a telescopic laser screed was purchased to handle large-area plant construction. A high-temperature-resistant engine and hydraulic system were selected to adapt to the high-temperature desert environment.

Usage Results:

• Fast construction speed; large areas can be completed before the concrete initially sets, without affecting quality due to rapid setting.
• High precision; even with strict requirements from Saudi clients, it passed inspection.
• Reduces reliance on local workers; a small team can handle the job.
• The equipment operates continuously at 50℃ with stable performance.

Customer Testimonial: “Saudi summers are hot, and many machines don’t work here; the high temperatures cause problems. We’ve used this YG machine for over a year, and it works perfectly even in 50-degree summer weather without any major issues. We’re very satisfied with the quality and plan to buy another one.” — Project Manager Ahmed

What Equipment Can Be Used in Conjunction with YG Telescopic Boom Laser Screeds?

Laser screeds are not standalone machines; on construction sites, they often need to be used in conjunction with other equipment to maximize efficiency. Below are several types of equipment from the YG product line that can be used with telescopic boom laser screeds:

1. Telescopic boom forklift. Also known as a telescopic forklift, the telescopic boom forklift is mainly used in laser screed construction for material placement—unloading concrete from the concrete mixer truck and transporting it to the work surface for pouring. Especially in large-area factory construction where mixer trucks cannot enter, the telescopic boom forklift’s bucket loads material, extends its boom, and delivers it, maximizing efficiency when used in conjunction with the laser screed. The forklift’s high boom and lifting height allow for use even in multi-story construction.
2. Aerial work platform. Laser screeds are used for the ground surface, while aerial work platforms are used for overhead piping, ceiling installations, and fire protection systems. After the ground surface is completed, the aerial work platform is immediately deployed for the overhead construction. For a single construction site, both ground and aerial work equipment can be rented together, offering one-stop purchasing for clients. YG has it all.
3. Excavators. For foundation excavation and earthwork, excavators are used to excavate the foundation and pit first, followed by laser screeding for final ground construction. For initial excavation and earthwork, excavators are used to dig trenches and excavate earth, while laser screeds are used for later flooring. All lines are available.
4. Cranes. In factory construction projects, cranes lift steel structures and equipment, while laser screeds are used for ground work. Both cranes and laser screeds are useful from foundation to roof.
5. Backhoe loaders (excavator loaders). For small to medium-sized construction sites, backhoe loaders can excavate earth and shovel and transport materials. Combined with laser screeds, they are the most practical all-around equipment for small projects, handling multiple tasks with one machine.
6. Concrete batching plants/batching machines. Ensuring a continuous supply of concrete allows laser screeds to operate continuously without interruption. Even the fastest screed is useless if the concrete supply can’t keep up.
7. Power trowel. After the initial setting of the laser screed, use a ride-on power trowel to finish the surface, resulting in a smoother and flatter floor. Laser screed + power trowel is the perfect combination for floor construction.
8. Road cutter. Cut expansion joints after the concrete is finished to prevent cracking.

Equipment Combination Recommendation: For large factory projects, we recommend a complete set including an excavator + concrete batching plant + telescopic boom forklift + laser screed + power trowel, providing a one-stop service from earthwork to finishing.
