A mobile concrete placing boom is designed for high-rise floor pouring where fixed booms cannot reach. It solves the problems of inconvenient operation, high labor costs, and slow pouring efficiency on traditional concrete placement booms. This portable concrete placing boom uses advanced R-fold arm technology for smooth, precise concrete distribution. No fixed installation needed. Just crane it to the floor. Place it on the slab. Start pouring.
YG Machinery offers YG-HGY12, YG-HGY13, YG-HGY15, YG-HGY17, and YG-HGY21 mobile concrete placing booms for high-rise construction, residential projects, and multi-site contractors.

Hydraulic concrete placing boom models available with diesel engine power option.
How a Hydraulic Concrete Placing Boom Works?
The concrete placement boom operates through a simple hydraulic system.
1. Crane hoisting relocation – The mobile placing boom is lifted by tower crane or mobile crane. No fixed installation required. Place it on the floor slab or platform.
2. 360° full rotation – The boom rotates a full circle. Hydraulic motors drive smooth, precise rotation. Pour concrete in any direction without repositioning the base.
3. R-fold boom extension – The R-shaped folding arms extend and retract. Reach up to 20.5 meters. Cover large floor areas from one position.
4. Wireless remote control – The operator controls boom movement from a safe distance. Raise, lower, extend, retract, and rotate. All at the touch of a button.
5. Concrete delivery – Concrete flows through the φ125mm pipe. The 3-meter end hose places concrete exactly where needed.
6. Quick relocation – When the floor is done, crane the boom to the next level. No disassembly. No reinstallation. Just lift and go.
This mobile concrete placing boom eliminates the need for fixed installation and reduces crane waiting time.
Applications of Concrete Placement Boom
High-rise building floor pouring
Pour floor slabs on high-rise residential and commercial buildings. Crane the boom to each floor. Pour. Move up. No fixed installation.
Confined space concrete placing
Work in tight spaces where truck-mounted booms cannot reach. The compact structure fits through doorways and narrow openings.
Platform concrete distribution
Pour concrete on bridge decks, parking structures, and industrial platforms. The boom reaches across wide areas from a central position.
Multi-site contractor work
Move the boom between job sites. No installation required on each site. Crane it on. Pour. Crane it off. Move to the next site.
Residential building construction
Pour concrete for apartments and condominiums. The 11.6-15m reach covers standard residential floor areas.
Construction with limited crane time
Place the boom early. Pour through the day. Crane it away when finished. One crane lift per floor.
One mobile concrete placing boom serves all these applications.
Customer Case: High-Rise Residential Project
A construction company in Southeast Asia was building a 35-story residential tower. Each floor required concrete slab pouring. The contractor used a fixed concrete placing boom. It took 2 days to install on each floor. Crane time was expensive. Labor was wasted waiting for installation.
The contractor switched to a YG-HGY15 mobile concrete placing boom. The boom was delivered folded. The tower crane lifted it to floor 10. Workers unfolded the arms. They started pouring within 30 minutes.
The results:
- Installation time dropped from 2 days to 30 minutes per floor
- Crane time reduced by 80%
- The project finished 15 days ahead of schedule
- The boom paid for itself on the first 10 floors
The site manager said: “We were wasting time installing fixed booms on every floor. The YG mobile boom changed everything. One crane lift, and we are pouring. We will use this on every project from now on.”
How to Choose the Right Concrete Placing Boom?
| Your project need | Recommended model | Why |
| Small residential floors, tight budgets | YG-HGY12 (11.6m) | Lightest weight, easy to crane |
| Standard residential floors | YG-HGY13 (13m) | Good balance of reach and weight |
| Commercial building floors | YG-HGY15 (15m) | Most popular, covers large areas |
| Large floor plates | YG-HGY17 (16.5m) | Extended reach for big slabs |
| Very large floors, high-rise | YG-HGY21 (20.5m) | Maximum reach, high capacity |
| Site without power supply | Diesel-powered model | Works anywhere, no power lines |
Consider your floor-to-floor height. The boom must fit in the elevator shaft or stairwell for transport.
Consider your crane capacity. The boom weight must be within your tower crane’s lifting capacity at the top floor.
Consider your floor slab size. Choose reach that covers the farthest pour point from the crane placement position.

Frequently Asked Questions
Q: What is the concrete placing boom price range?
A: Price depends on model (HGY12 to HGY21) and power type (electric or diesel). Contact us for a concrete placing boom price quote.
Q: Does it need fixed installation?
A: No. Place it on the floor slab or platform. No anchor bolts. No foundation work. Just crane it on and start pouring.
Q: How is it moved between floors?
A: Use a tower crane or mobile crane. Lift the boom by its lifting points. Move to the next floor. Place it down. Start pouring.
Q: What power source does it need?
A: Electric models need 380V/50Hz power. Diesel models have an onboard engine. Choose diesel for sites without reliable power.
Q: How long does setup take?
A: 30-60 minutes from arrival to pouring. Unfold the arms. Connect power or start the diesel engine. Calibrate the remote control. Start pouring.
Q: Can it be used outdoors?
A: Yes, but maximum wind speed during operation is limited. Check the specifications for wind limits.
Q: What safety features does it have?
A: Overload protection. Limit switches on boom angles. Pressure relief valves. Emergency stop on the remote control.
