Multi-purpose, efficient and convenient
Self loading concrete mixers loading, mixing, transportation and fixed-point unloading functions in one, can replace loaders, mixers, transport vehicles and other machinery, greatly improve the work efficiency, reduce equipment investment and operator needs.
High efficiency operation
This type of vehicle is usually equipped with an efficient mixing system, such as an average of 16 revolutions per minute, an average of 12 minutes to complete the mixing of a can of material, and some can even complete the discharge within 5 minutes, greatly speeding up the construction progress.
High flexibility
Suitable for a variety of terrain, does not rely on external power equipment, can move freely on the site to meet the needs of different construction sites, especially for remote or complex terrain sites.
Cost saving
High degree of automation, reduce manual dependence, save labor costs. At the same time, on-site mixing reduces the transportation and waiting time of concrete, reduces material waste, and saves material costs.
Environmental friendly
Compared with the traditional mixing station, the self loading concrete mixers can reduce the need for long-distance transportation of concrete, thereby reducing environmental pollution during transportation, including dust, waste water and exhaust gas. In addition, on-site mixing reduces mixing time and reduces noise pollution.
Strong adaptability
It is suitable for complex environments such as rural roads and mountain areas, and solves the problem of "road resistance", that is, it can work under different road conditions, including mountain, pit, plateau and so on.
Ease of Maintenance
Self loading concrete mixers are designed for easy maintenance, with accessible components that can be quickly inspected and repaired. This helps to prolong the equipment's lifespan and minimize downtime due to unexpected breakdowns.
Application of Self Loading Concrete Mixers
Residential Construction
In residential construction, self loading concrete mixers are commonly used for tasks such as foundation pouring, driveway installation, and landscaping. Their versatility and compact size make them well-suited for small-scale projects where space is limited.
Commercial Construction
Self loading concrete mixers are also widely used in commercial construction projects, including retail developments, office buildings, and industrial facilities. Their ability to deliver freshly mixed concrete directly to the job site ensures timely completion of construction tasks, helping to meet tight deadlines and budget constraints.
Infrastructure Projects
Infrastructure projects such as road construction, bridge building, and utility installation also benefit from the use of small self loader concrete mixer. These machines enable contractors to mix and deliver concrete on-demand, even in remote or hard-to-reach locations, facilitating efficient progress and cost-effective construction.
Loading system
The loading system is an important part of the self loading concrete mixer, usually including the loading hopper, loading arm, hydraulic system, etc. The hydraulic system controls the loading arm, which can adjust the position flexibly and feed the raw materials such as sand, gravel, cement and so on into the mixing drum precisely.
Mixing system
Mixing system is the core part of self loading concrete mixer. It mainly consists of mixing cylinder, mixing blades, driving device and so on. The mixing drum rotates under the driving device, while the mixing blades keep rolling and mixing inside the drum, so that the concrete raw materials are evenly mixed to reach the predefined quality standard.
Weighing system
The weighing system is a critical component for achieving the perfect mix. It ensures that the right proportions of materials are used.Sensors and load cells integrated into the loading bucket and drum measure the weight of the materials. The system then displays this information on a digital screen in the operator cabin.
Travelling system
The travelling system includes chassis, wheels, drive shafts, etc., which gives the self loading mixer truck flexible mobility and enables it to travel freely in the construction site and complete the whole process of feeding, mixing, transporting and unloading conveniently and quickly.
Discharge system
The unloading system consists of unloading hopper, unloading door and hydraulic system. Through the control of hydraulic system, the unloading gate can be opened and closed precisely, and the mixed concrete can be unloaded to the designated position quickly and evenly to ensure the construction quality.
Control panel
The control panel includes various switches, levers, and buttons. Operators use these controls to manage the loading, mixing, and discharging processes. The panel also displays important information such as fuel levels and maintenance alerts.
Engine and transmission
The engine and transmission are the powerhouse of the self loading concrete mixer. They provide the necessary power to operate the machine's various functions.
Loading raw materials: Self loading concrete mixer is equipped with a bucket similar to a loader, which automatically loads raw materials such as sand, stone, cement, etc. through the bucket. During operation, the driver can control the lifting and forward direction of the bucket through the control system inside the cab, and feed the raw materials into the mixing bucket. This process can be completed automatically, reducing manual operation.
Precise ingredients: During the process of loading raw materials, the self loading concrete mixer truck accurately calculates the ratio of each raw material through an automated system. This usually relies on sensors and electronic control systems to ensure that the concrete mix ratio meets the set standards and guarantees the quality of the concrete.
Mixing: After all the raw materials are loaded, the mixing drum begins to operate. The self loading concrete mixer truck adopts strong mixing blades, and the mixing bucket rotates around the axis to ensure that all raw materials are evenly mixed. During the mixing process, cement reacts with other raw materials to form a uniform concrete slurry.
Transportation: Once the concrete is mixed, the mixing bucket will continue to rotate to prevent the concrete from clumping. Then, the self loading concrete mixer can be directly transported to the construction site. Due to the inclined design of the mixing drum, concrete can be easily released and transported to the location where it needs to be poured through the inclined hatch.
Unloading: After arriving at the construction site, the driver can tilt the mixing bucket through the control system to evenly unload the concrete to the designated location. Unloading is usually controlled by a hydraulic system, and the unloading process is smooth.
