A concrete spreader is a hydraulic placing boom that distributes concrete evenly across large areas. This concrete placing boom replaces manual labor for concrete distribution. One machine replaces 4-5 workers and works 3-5 times faster. For high-rise building floor pouring, super high-rise core walls, and large foundation slabs, this concrete distribution boom saves labor and speeds up construction.
YG Machinery offers hydraulic concrete placing booms from YG-HGY12 to YG-HGY21. Working radius ranges from 12 to 21 meters. All models feature R-folding arms, 360° rotation, wireless remote control, and crane-hoisting mobility.

Manual Spreading vs Concrete Spreader
Spreading concrete by hand with shovels is slow, tiring, and expensive. A concrete spreader does the work faster and more evenly.
| Comparison | Manual Spreading | Concrete Spreader |
| Workers needed | 4-5 people | 1 operator |
| Speed | Slow | 3-5 times faster |
| Labor cost | High | 60% less |
| Coverage | Uneven | Uniform and precise |
| Physical effort | Very high | Low |
| Best for | Small jobs | Any size, especially large areas |
What this means for your business:
A concrete spreader pays for itself quickly. With 60% labor savings and 3-5 times faster speed, most contractors recover the investment in 6-12 months. Every project after that is pure savings.

Key Features of Concrete Spreader Machine
R-folding arm design – The unique R-folded arm allows compact storage and wide reach. Unfolds quickly on site.
360° full rotation – Continuous rotation covers the entire floor area. No manual repositioning needed during a pour.
Wireless remote control – One operator controls everything from any position. Stay away from moving parts and the concrete flow.
No fixed installation – The concrete placing equipment does not need bolts or anchors. Crane lifts it to each floor. Flexible and fast.
Hydraulic system – Smooth and precise arm movement. Accurate control for tight spots and edges.
Compact for hoisting – Designed to fit through elevator shafts and floor openings. Easy to move between floors.
Durable concrete pipe – φ125mm pipe handles standard concrete mixes. 3m end hose for flexible placement.
Simple operation – Controls are intuitive. One worker learns in one day.

Application of Concrete Spreader Machine
Many contractors now prefer a crawler concrete placing boom because it improves both project management and concrete placement quality.
- Faster Concrete Placement: The machine continuously pumps concrete to the pouring area without repeated manual handling.
- Better Reach on Complex Sites: Upper building floors, bridge structures, tunnel sections, and underground foundations.
- Lower Material Waste: Concrete moves directly through pipelines, reducing spills around the site.
- Cleaner Construction Areas: Compared with manual transfer methods, pumping systems keep the work area more organized.
- Reduced Equipment Movement: Workers no longer need to repeatedly reposition temporary conveyors or pipelines.
Tunnel lining – Place concrete on tunnel walls and ceilings. No outriggers means no blocked lanes. Move forward as lining progresses.
Pile foundations – Pour concrete into deep foundation holes. Reach over rebar cages. Move between piles without repositioning.
Bridge construction – Place concrete on bridge decks and abutments. Work from embankments and rough ground.
Hydroelectric dams – Pour large volumes of concrete. Cover wide areas with 360° rotation and 20m reach.
Mountain roads – Work on uneven terrain. Track system handles slopes and rocks.
Large infrastructure – Airports, ports, power plants. Any project that needs concrete placed over a large area.
Outdoor heavy construction – No overhead cover. Full arm extension. Full rotation. Maximum productivity.

How to Choose the Right Concrete Spreader?
Choosing the right concrete spreader depends on your building height and floor area.
| Your project type | Recommended model | Why |
| Small residential, 1-5 floors | YG-HGY12 | 12m radius, compact, lower cost |
| Medium residential, 5-10 floors | YG-HGY13 or YG-HGY15 | 13-15m radius, good coverage |
| Large residential, 10-20 floors | YG-HGY17 | 16.5m radius, high reach |
| High-rise, 20-30 floors | YG-HGY21/3 | 20.5m radius, 3-section arm |
| Super high-rise, large floor area | YG-HGY21/4 | 20.5m radius, 4-section arm, more reach options |
| Large commercial building | YG-HGY21/4 | Highest capacity, max coverage |
| Complex layout with obstacles | YG-HGY21/4 | More arm sections for flexible movement |

Customer Case
A mid-sized construction company was pouring concrete floors for a 15-story residential building. They used 4 workers with shovels to spread concrete from the pump hose. It took 6 hours to cover one floor. Workers were tired. The concrete set before fully spread in some areas. Quality was inconsistent.
They bought a YG-HGY17 concrete spreader. The machine was hoisted to each floor. One operator controlled the boom by wireless remote. Concrete came from the pump, through the boom pipe, and spread evenly across the floor.
Results:
- Pour time reduced from 6 hours to 2 hours per floor
- Workers reduced from 4 to 1 operator
- Concrete spread evenly, no weak spots
- The developer finished 3 months ahead of schedule
- The machine paid for itself in 8 months
The project manager said: “The concrete spreader changed how we pour floors. We finish faster, use fewer workers, and the concrete quality is better. I will use this on every project from now on.”

FAQ
Q: How far can this concrete spreader reach?
A: Models range from 11.6m (YG-HGY12) to 20.5m (YG-HGY21). Choose based on your floor area.
Q: Can it be used on any floor of a high-rise building?
A: Yes. The machine is crane-hoisted to each floor. It does not need fixed installation. Move it up as the building rises.
Q: How many workers does it take to operate?
A: One operator with the wireless remote control. The machine does the spreading work.
Q: Does it need to be bolted down?
A: No. The concrete placement boom uses its own weight and counterweight for stability. No bolts or anchors needed.
Q: What is the pouring speed compared to manual spreading?
A: The concrete spreader machine works 3-5 times faster than manual spreading with 4-5 workers.
Q: Can it handle different concrete mixes?
A: Yes. The φ125mm pipe handles standard concrete mixes used in residential and commercial construction.
Q: How long does it take to learn to operate?
A: Most operators learn in one day. The wireless remote and controls are simple and intuitive.
Q: What is the warranty?
A: The main structure has a 24-month warranty. Hydraulic and electrical components have a 12-month warranty.
