Self Loading Concrete Mixer:The Core Equipment Of Modern Infrastructure Projects.
What is self loading concrete mixer?
Concrete self-loading truck, usually refers to self-loading concrete mixer truck, is a multi-functional vehicle that integrates automatic loading, mixing, transportation and unloading functions. Concrete mixer truck self loading can complete the production, transportation and unloading process of concrete on the construction site by itself without relying on other equipment, which greatly improves the construction efficiency and flexibility.
Self loading concrete mixers can automatically produce and transport concrete on-site for its self-loading design, and concrete pump trucks can discharge concrete at 270 degrees, which is much more convenient in all kinds of constructions.
Importance of self-loading concrete mixer
Why do we need self-loading concrete mixer?
As a key equipment of modern engineering machinery, Concrete Pump Trucks with Self-Loading Capabilities can completely change the traditional concrete construction mode by integrating loading, transportation and pumping functions. It plays an irreplaceable role in engineering fields such as construction, roads, bridges, etc.
Significant advantages of the self-loading concrete mixer truck:
- Time control: The transportation volume per hour reaches 8-12m³ (data source: Construction Machinery Industry Association), which is 300% higher than the traditional transportation efficiency
- Quality assurance: The constant speed mixing system (speed 8-12 rpm) ensures that the concrete slump loss is less than 10%
- Cost optimization: A single device can replace the operation combination of 3 traditional transport vehicles + 2 loaders
Revolutionary application of self loading concrete mixer truck in construction engineering
Improved vertical transportation efficiency of high-rise buildings
Modern self-loading concrete trucks are equipped with plunger pump systems, and the vertical transportation height can reach more than 400 meters (such as the German Putzmeister ultra-high pressure pump truck), which is 80% higher than the traditional tower crane lifting efficiency. During the construction of the Shanghai Tower, multiple supporting pump trucks were used to achieve a vertical concrete pumping speed of 6 cubic meters per minute, shortening the construction period by 23 days.
Precise casting of complex structures
- Technical breakthrough: integrated GPS positioning and BIM model linkage system, with error control within ±3mm (refer to ACI 304R-12 casting specification).
- Construction scene: special-shaped curtain walls, steel structure nodes and other parts can be cast without formwork, reducing material waste by 15%.
Efficiency innovation in road engineering of self loading concrete mixer truck.
Asphalt pavement rapid paving technology
The self-loading truck directly connects to the paver hopper, reducing the waiting time for traditional dump trucks to unload, and increasing the paving area per day by 40%.
- Dynamic proportioning system: The on-board weighing sensor realizes real-time adjustment of the aggregate/cement ratio, which meets the ASTM C94 slump control requirements.
- Environmental compliance: The closed silo design makes the dust emission less than 10mg/m³, meeting the EPA Tier4 final emission standards.

How does a concrete self-loader work?
Working principle of self loader concrete mixer
The working principle of a concrete dump truck can be divided into the following steps:
1. Mixing concrete
The concrete dump truck drives to the concrete mixing station and loads the concrete raw materials into the mixing tank. Start the engine to drive the mixing tank to rotate, and start the water pump at the same time to add an appropriate amount of water. The mixing blades in the mixing tank fully mix the concrete raw materials to make them evenly mixed.
2. Transporting concrete
After the concrete is mixed evenly, the concrete dump truck can start driving. During the driving process, the concrete in the mixing tank is constantly stirred by the mixing blades to maintain its uniformity and fluidity. Concrete dump trucks generally use hydraulic transmission, and the speed and steering angle can be adjusted as needed.
3. Unloading
After the concrete dump truck arrives at the unloading point, it parks the car at the unloading position and unloads the concrete by controlling the unloading system. When unloading, first start the unloading motor, extend the cylinder outward, and align the unloading port with the unloading position. Then start the unloading motor to unload the concrete to the designated position.
4. Cleaning
Concrete dump trucks need to be cleaned after unloading to prevent concrete residue from damaging the vehicle. When cleaning, the remaining concrete in the mixing tank needs to be rinsed clean with water, and the cleaning water needs to be discharged to a designated location to avoid pollution to the environment.
Cement self loading truck structure
Concrete dump trucks are mainly composed of the following parts:
1. Chassis
The chassis is the basic part of the concrete dump truck, including the frame, engine, transmission system, steering system, braking system, suspension system, etc. The quality and performance of the chassis directly affect the safety, stability and driving performance of the concrete dump truck.
2. Mixing tank
The mixing tank is the core part of the concrete dump truck, mainly composed of the tank body, tank cover, feed port, discharge port, mixing blades, etc. The size and shape of the mixing tank are designed according to different needs and uses, generally in a round or oval shape. The mixing blade is the key part of concrete mixing, and its number, shape, angle and other parameters will affect the mixing quality and efficiency of concrete.
3. Unloading system
The unloading system is the discharging part of the concrete dump truck, mainly composed of the unloading port, unloading barrel, unloading motor, cylinder body, etc. The unloading port is located at the bottom of the mixing tank, and the movement of the unloading motor and cylinder body is controlled electrically or hydraulically to realize the unloading of concrete. The performance and stability of the unloading system directly affect the unloading efficiency and quality of concrete.
4. Water system
The water system is an auxiliary part of the concrete dump truck, mainly composed of a water tank, a water pump, a water pipe, a spray device, etc. The main function of the water system is to add an appropriate amount of water during the concrete mixing process to ensure the fluidity and consistency of the concrete.

What are the application advantages of SMAT concrete self-loaders?
Highly automated
Automatic loading and mixing: Equipped with hydraulically driven loading arms and buckets, it can automatically grab and lift raw materials such as sand, gravel, cement, etc. and load them into the mixing bucket. At the same time, the mixing bucket can continuously mix during the vehicle’s driving process to ensure that the concrete is mixed evenly.
Automatic transportation and unloading: After mixing, the concrete self-loader can directly transport the concrete to the construction site, and accurately guide the concrete to the desired position through the tiltable mixing tank and unloading chute.
Accurate weighing system
High-precision measurement: Using advanced weighing technology such as cylinder measurement and control weighing scheme, the error can be controlled within 2%, which is much lower than the error of other products on the market. This ensures the accurate proportion of concrete raw materials and improves the quality and consistency of concrete.
Real-time monitoring and adjustment: The weighing system can display and record the weight of the loaded raw materials in real time, and automatically adjust the proportion of ingredients according to the weighing data. The operator can also monitor and adjust the weighing data in real time through the control panel to ensure the correct mixing ratio.
Strong flexibility and adaptability
Small size and strong maneuverability: The concrete self-loading truck is small in size and can operate in small spaces and various terrains. For example, it can also move flexibly in narrow streets in the city or complex construction sites to complete the production and transportation tasks of concrete.
