Placing concrete on a high-rise construction site sounds simple. But many contractors struggle with slow manual distribution, workers carrying heavy hoses, and concrete that sets before reaching the right spot. A concrete placing boom solves these problems fast. It delivers concrete exactly where needed with precise hydraulic control. One operator controls the boom from the ground or the platform. No workers carrying hoses. No wasted concrete.
YG Machinery offers YG-HGY series (mobile and internal climbing) and YG-HGL series (crawler) concrete placer booms for high-rise buildings, tunnels, and complex construction sites.

How a Hydraulic Concrete Placer Boom Works?
The hydraulic concrete placing boom operates through an advanced hydraulic system.
Step 1: Pump the concrete – A concrete pump pushes concrete through the delivery pipeline to the boom.
Step 2: Extend the boom – The R-fold, Z-fold, or M-fold arms unfold to the required position. The hydraulic system controls each arm section independently.
Step 3: 360° rotation – The slewing mechanism rotates the boom full circle. The boom reaches any point within its radius.
Step 4: Elevation control – The boom lifts up to 90° to reach upper floors or low points. Precision control places concrete exactly where needed.
Step 5: Remote operation – The operator controls everything from a distance using a wireless remote. No one stands under the boom while it moves.
The load-sensing hydraulic system ensures smooth, efficient movement. The boom operates quietly and precisely.
Key Advantages of Concrete Placing Boom
Precise concrete placement – Place concrete exactly where you need it. No overspill. No waste.
One-person operation – One operator controls the boom from the ground or platform. No crew carrying hoses.
360° full rotation – Reach every point within the boom radius. No repositioning needed for standard pours.
R-fold boom technology – The R-shaped folding arms open and close smoothly. Compact when folded for transport.
Works on any floor – Set up on slabs, platforms, or simple bases. No special foundation needed for mobile models.
Climbing capability – Internal climbing models rise with the building. The boom stays at the right height as the building grows.
Remote control – Wireless operation from a safe distance. Better visibility. Better safety.
Hydraulic system – Smooth, precise movements. No jerking. No sudden swings.
Installation Methods: Choose What Fits Your Site
Mobile/fixed type – Placed on a floor slab or platform. Can be moved by crane to different locations. Best for lower buildings and floor-level pouring. YG-HGY12/13/15/17.
Internal climbing type – Uses the building’s elevator shaft or dedicated tower system. The boom climbs upward as the building grows. Best for super high-rise buildings up to 32m reach. YG-HGY19/21/24/28/32.
Crawler type – Self-propelled on tracks. Moves around complex job sites. Best for large areas where mobility is needed. YG-HGL series.
Why this matters: The right installation method saves time on setup and keeps the boom working at the right height for every pour.
Applications of Concrete Placing Equipment
High-rise building construction – Pour floor slabs, columns, and core walls. The internal climbing boom rises with the building.
Super high-rise with elevator shaft – Use the elevator shaft for climbing. The boom reaches up to 32m.
Complex construction sites – The 360° rotation reaches around obstacles. Place concrete in tight areas.
Floor slab concrete pouring – Cover large floor areas quickly. One position covers multiple pouring points.
Large area concrete placement – Move the boom across the pour area. Cover large slabs without repositioning.
Tunnel construction – Use crawler models in tunnels. Move as the tunnel progresses.
Bridge construction – Place concrete on bridge decks and piers. The boom reaches over edges and barriers.
Industrial facilities – Pour large factory floors and equipment foundations.
One concrete placing boom serves all these industries.
Customer Case: Super High-Rise Building in Dubai
A construction company in Dubai was building a 45-story residential tower. The project required concrete pouring for 45 floor slabs. Each floor was 600m². Manual distribution using hoses required 8 workers per floor and caused delays. Concrete often set before reaching the far end of the slab.
The contractor chose a YG-HGY21 internal climbing concrete placer boom. The boom was installed in the elevator shaft. It climbed with the building, always staying 2 floors above the pour level.
The results:
- One operator controlled the boom from the ground
- Pour time dropped from 4 hours to 2 hours per floor
- Workers reduced from 8 to 1 for boom operation
- The building finished 2 months ahead of schedule
- Concrete quality improved with no cold joints
The project manager said: “The concrete placing boom was essential for keeping our schedule. We poured each floor in half the time. One man operated the boom. The rest of the crew focused on finishing. We could not have finished on time without it.”
How to Choose the Right Concrete Placement Boom?
| Your project type | Recommended model | Why |
| Low-rise building, floor level pouring | YG-HGY12 or YG-HGY13 | Mobile, easy to move between floors |
| Mid-rise building, 10-20 stories | YG-HGY15 or YG-HGY17 | Good balance of reach and portability |
| High-rise building, 20-40 stories | YG-HGY19 or YG-HGY21 (internal climbing)YG-HGY19 or YG-HGY21 (internal climbing) | Climbs with the building |
| Super high-rise, over 40 stories | YG-HGY24/3 to YG-HGY32/3 | Longest reach, internal climbing |
| Complex site, multiple locations | YG-HGL series (crawler) | Self-propelled, moves around site |
Consider these factors:
- Building height (number of stories)
- Floor slab size and shape
- Accessibility for installation
- Need for climbing or mobility
- Budget and timeline

Frequently Asked Questions
Q: What is the price of a concrete placer boom for sale?
A: Price depends on type (mobile, internal climbing, or crawler), boom length, and control system. Contact us for a quote based on your project.
Q: What is the difference between YG-HGY and YG-HGL series?
A: YG-HGY series includes mobile and internal climbing booms. YG-HGL series are crawler-mounted for mobility on complex job sites.
Q: What is the maximum reach of your concrete placement boom?
A: The YG-HGY32/3 reaches 32m horizontally. Mobile models range from 11.6m to 20.5m. Crawler models reach up to 20.5m.
Q: Can it be used in tunnels?
A: Yes. The YG-HGL crawler series is ideal for tunnel construction. The tracks move easily in confined spaces.
Q: What power source does it need?
A: Standard models run on 380V/50Hz power. Diesel engine options available for YG-HGL crawler models and off-grid sites.
Q: Is training required to operate it?
