Indoor construction spaces are often tight, making secondary structure work in high-rise buildings slow and difficult. Traditional manual wheelbarrows waste labor and cannot guarantee dense concrete filling. A cantilever secondary concrete pump changes this reality completely. As a direct machinery manufacturer, the YG engineering team optimized the hydraulic pumping system to make indoor movement and high-level placing simple and efficient.
Tip: Always check your stone size before buying. Our machines are built for 5-16 mm aggregate, which is the perfect size to prevent pipe blockages during high-pressure indoor pumping.
Cantilever Secondary Concrete Pump Parameter
When selecting a column pouring machine, knowing the exact technical facts helps you avoid the wrong model. A reliable machine must balance delivery pressure and pumping height perfectly.
Here are the core technical specifications of the YG cantilever secondary concrete pump:
| Model | YG-300 | YG-400 | YG-500 |
| Vertical Conveying Height | 3M | 4M | 5M |
| Horizontal Conveying Distance | 3M | 4M | 5M |
| Motor Power | 3KW | 7.5KW | 7.5KW |
| Rated Voltage | 380V | 380V | 380V |
| Key Technical Indicators | Standard Parameter Range | Practical Jobsite Benefit |
| Fine stone aggregate size | 5 – 16 mm | Avoids pipe blockages completely and ensures smooth output |
| Vertical delivery distance | 25 – 30 meters | Meets continuous pumping needs for a 10-story building easily |
| Actual productivity | 5-7m³/h | Pours 15-20 structural columns quickly every hour |
| Equipment investment cost | $2,900 – $4,500 | Factory-direct price; returns your investment in just 1 month |
Tip: Some trading companies exaggerate pumping heights online. In reality, if the delivery pressure is below 15 MPa, maintaining a stable vertical height above 25 meters is impossible.
What is a Secondary Structure Pouring Machine?
On construction sites, a secondary structure pouring machine is a light pumping equipment built specifically for transporting fine stone concrete. Contractors use it mainly for indoor structural columns, lintels, and parapet walls in high-rise buildings. This machine has a small body and fits directly into construction elevators, solving the final 100-meter indoor transport problem in tall buildings.
With the rise of high-rise building projects, this efficient secondary structure pouring machine has become an essential tool for modern construction crews to increase speed.
Why Choose a Cantilever Secondary Structure Concrete Pump?
Standard concrete pumps require workers to dismantle and move heavy pipes under high physical strain. However, a cantilever secondary structure concrete pump features a rotatable mechanical boom. This cantilever extends directly over indoor obstacles, placing the hose outlet right above the column top. Workers do not need to move pipes constantly, which cuts physical labor by 60%.
Wide Application Scenarios and Field Cases
Core Application Fields
- High-Rise Residential Projects: Used for thousands of indoor structural column pouring tasks.
- Commercial Shopping Malls: Pours concrete quickly for top lintels of firewalls and partition walls.
- Tunnels and Underground Projects: Handles localized grouting in basements where headspace is highly restricted.
Success Case: Commercial Center Project in Mexico
Last year, a construction contractor named Mr. Alejandro in Mexico faced a tight project deadline. His team was building a 4-story commercial center with 450 internal structural columns. Heavy pump trucks could not enter the tight indoor space, and manual pouring was too slow.
Alejandro purchased two units of the YG cantilever secondary concrete pump.
The machines moved to target floors easily via temporary elevators. Workers used the wireless remote control feature to adjust the cantilever position and control the pump while standing safely next to the columns. Consequently, his team cut the pouring time per column from 25 minutes to under 5 minutes. Alejandro told us these two machines saved him 14 workers and finished the project 12 days early.
Why YG is Your Reliable Machinery Manufacturing Partner
YG is a physical factory focused on R&D and manufacturing; we sell high-quality machinery only, not concrete materials. Our machines use a smart floor space optimization design, with a frame width of just 75 cm to pass through narrow indoor doors easily. Furthermore, we equip all models with a high-strength wear-resistant concrete pipe, extending the service life by more than 45% compared to standard pipes.
Customer Frequently Asked Questions
The machine is engineered for fine stone aggregate ranging from 5 mm to 16 mm. Do not use stones larger than 20 mm, as they increase the risk of clogging the lines significantly.
Depending on your configuration (such as electric or diesel power), the official YG factory price ranges from $2,600 to $4,500. We keep stock in our workshop year-round, and shipping to major ports in the US or Europe takes 20-35 days.
This happens often on construction sites. Besides the standard 380V electric motor, YG offers custom compact diesel engine options or models that run on 220V single-phase power. This lets you start your work smoothly on any site without industrial power.
