In infrastructure construction, the demand for large-scale pouring of concrete on medium-sized sites, combined with high efficiency and flexibility, is most common. Traditional small-scale mixing equipment suffers from insufficient capacity, large-scale equipment faces site limitations, and the cumbersome relocation of fixed concrete mixing plants has consistently plagued engineering contractors. Addressing this industry pain point, Haomei Machinery has focused on equipment R&D, creating the self loading concrete mixer with capacity of 4 m3. As the brand's flagship mid-range product, this model is precisely positioned for medium-sized infrastructure construction scenarios. With its balanced performance parameters, stable operation, and high adaptability, it has become the mainstream preferred equipment for municipal engineering, industrial and mining construction and road construction.

Regarding core operating parameters, this model boasts a standard effective discharge capacity of 4m³, a golden specification that balances flexibility and capacity. The equipment is equipped with a high-performance 4108 turbocharged diesel engine, providing ample power reserves and a rated power of up to 91kW. Its stable and powerful output allows it to handle continuous high-intensity construction operations. The machine features an optimized mixing chamber structure and employs double-spiral wear-resistant mixing blades, resulting in a more uniform material mixing trajectory. This completely eliminates concrete segregation and clumping, ensuring uniform and stable strength of the finished concrete. The standard operating cycle time is only 10 minutes, continuously producing 22 cubic meters of high-quality concrete per hour, with a stable daily production capacity exceeding 180 cubic meters, fully meeting the continuous pouring needs of medium-sized projects.

Site adaptability and mobility are key highlights of the 4 cubic meter self loading concrete mixer model. Compared to the 6.5 cubic meter large self loading concrete mixer equipment, this model has a more compact size, more flexible steering, and stronger maneuverability. It does not require a large construction site and can freely enter and exit narrow construction sites in towns, factory areas, and rural main roads. Equipped with a heavy-duty chassis and professionally optimized counterweights, it can climb slopes up to 30°, easily handling complex construction site conditions such as mud, steep slopes, and unpaved roads. It requires no additional towing equipment, enabling autonomous relocation and perfectly solving the industry problem of fixed concrete mixing plants being unable to move and incurring high relocation costs.

In terms of construction precision and intelligent configuration, self loading concrete mixer with capacity of 4m3 is equipped with a complete intelligent metering and control system, controlling the error of sand, cement, and water proportions within ±1%. The entire process is automated and precise, eliminating the need for repeated manual calibration and effectively ensuring the quality of concrete pouring. The equipment integrates automatic feeding, intelligent mixing, 270-degree omnidirectional rotating unloading, and high-pressure automatic cleaning functions. The entire construction process can be completed by a single operator, significantly reducing labor costs. Compared to traditional manual mixing methods, overall construction efficiency is increased by more than 50%.

Durability and low maintenance costs make it well-suited for complex overseas construction scenarios. The mixing drum is constructed from thickened wear-resistant steel plates, and core consumable components undergo high-frequency quenching, resulting in excellent wear and impact resistance and a low failure rate during long-term continuous operation. The 4m3 self loading concrete mixer equipment requires no external power supply, operating independently with diesel power, making it suitable for remote construction environments without power grids or with power shortages.

With its balanced overall performance, the self loading concrete mixer with capacity of 4m3 has become one of the most widely applicable and repurchased models for medium-sized infrastructure projects worldwide, thanks to its core advantages of being suitable for any site, highly efficient and stable, and offering excellent value for money.
