1. Product Overview
The
DAYUN 4×2 7.5m³ Concrete Mixer Truck is an upgraded high-capacity and cost-effective light-duty concrete transport equipment, perfectly bridging the performance gap between small 4–5m³ light mixers and bulky 6×4 heavy mixers. It adopts a professional 4×2 single-axle layout with a super-short 3600mm wheelbase and 7.65m ultra-compact overall length, achieving a perfect balance of large loading volume, flexible maneuverability and low operating investment, which is highly suitable for various restricted and complex construction sites.
This model features outstanding structural stability and durability. It is equipped with a double-layer reinforced frame and a 10-ton heavy-duty rear axle, maintaining stable full-load operation without shaking or deformation. Matched with parabolic spring suspension, the chassis delivers excellent shock absorption performance, adapting to bumpy and rough construction roads and effectively reducing the overall vehicle breakdown rate. Powered by a reliable 200HP Yuchai engine, the powertrain outputs strong low-RPM torque, providing powerful climbing capacity for mountainous road conditions while achieving 8%–12% lower fuel consumption than peer competitors, with globally accessible spare parts and complete overseas after-sales service network.
The mixer superstructure adopts heavy-duty industrial standard configuration with precise parameter design. It has an effective mixing volume of 7.5m³ and a geometric volume of 10.2m³. The mixing drum is made of high-strength Q345 wear-resistant manganese steel, with a 4mm-thick drum barrel and 6mm-thick end caps, equipped with thickened anti-wear mixing blades to resist concrete abrasion and adhesion. The hydraulic system comes with standard integrated pump/motor/reducer assembly, with optional USA Eaton hydraulic pump/motor and Italy Bonfiglioli reducer for higher precision and stability. The drum supports 0–14rpm stepless speed adjustment, with a concrete residual rate controlled ≤0.7% to minimize raw material waste. Complete auxiliary configurations include a 350L stainless steel washing tank, full-set feeding and discharging chutes, safety ladder and maintenance platform.
In terms of driving comfort and export adaptation, the truck is factory-fitted with premium configurations: original factory A/C, power steering, airbag shock-absorbing driver seat, electric windows and remote central lock, paired with panoramic extended mirrors to relieve long-shift driving fatigue. For global market demands, it supports switchable LHD/RHD steering layout and customizable emission packages from Euro II to Euro VI, fully complying with vehicle registration and environmental standards in Southeast Asia, Central Asia, Africa and other mainstream overseas markets.
2. Working Principle
The DAYUN 4×2 7.5m³ concrete mixer truck relies on the strong low-speed torque output of the 200HP Yuchai engine to drive the full hydraulic circulating mixing system. Stable power is continuously transmitted to the hydraulic assembly, driving the Q345 manganese steel mixing drum to operate at 0–14rpm stepless adjustable constant speed during transportation, realizing automatic feeding, uniform stirring and quantitative discharging.
Benefiting from the thickened drum structure and optimized thickened mixing blades, the equipment effectively prevents concrete segregation, sedimentation and solidification during long-distance and bumpy transportation, ensuring uniform and qualified concrete quality on arrival. When upgraded with optional imported USA Eaton and Italy Bonfiglioli hydraulic components, the system features superior tight sealing, stable operation and high mixing accuracy, further reducing concrete adhesion and achieving a ultra-low residual rate of ≤0.7%, greatly reducing material waste and post-operation cleaning workload.
Equipped with a 350L stainless steel circulating water cleaning system, the truck can thoroughly flush residual concrete inside the drum, feeding port and discharging chutes after each operation to avoid material caking and equipment blockage. Supported by the double-layer reinforced frame, 10T heavy rear axle and parabolic suspension system, the whole vehicle maintains stable load-bearing performance under frequent start-stop and rough road working conditions, ensuring long-term low-failure continuous operation.
3. Daily Application Scenarios
With its large capacity, flexible passing performance and stable full-load operation capability, the DAYUN 4×2 7.5m³ mixer truck is widely applicable for medium and small-scale infrastructure construction projects. It perfectly serves rural self-built housing, rural road paving and upgrading, township municipal renovation, slope protection engineering, irrigation ditch construction, small precast component factories and micro rural ready-mix concrete stations.
Thanks to its compact body and short wheelbase design, the truck can freely navigate narrow rural roads, height and width restricted construction sites and mountainous working areas that large 6×4 heavy mixers cannot access. It is highly suitable for short-term rental business of small and medium engineering teams. With 50% higher transport capacity than traditional 4–5m³ small mixers, it significantly improves construction efficiency, becoming the preferred equipment for grassroots infrastructure and small-scale engineering projects in Southeast Asia, Central Asia and African markets.
4. Comparison With Traditional Models
Compared with traditional 4–5m³ small light-duty mixer trucks, the DAYUN 7.5m³ model boasts 50% higher single-vehicle transport capacity, effectively reducing delivery frequency and shortening project cycles. It solves the core pain point of insufficient supply capacity of small mixers for medium-volume concrete projects, greatly improving overall construction efficiency.
Compared with 6×4 tandem 8–10m³ heavy-duty mixer trucks, this 4×2 single-axle model has much lower purchase cost, insurance fees, road tolls and daily maintenance expenses. It avoids the high investment threshold and high operating cost of heavy mixers, bringing faster return on investment for fleet owners and small and medium construction enterprises.
In terms of comprehensive performance, this model achieves a perfect balance of flexibility and load capacity. Its short wheelbase and compact body realize superior site maneuverability for narrow and restricted working scenarios. The double-layer reinforced frame and 10T heavy rear axle provide more stable full-load operation than ordinary light mixers, with lower breakdown rates on rough roads. The thickened manganese steel drum and optional imported hydraulic parts deliver longer service life and lower concrete waste rate, while the fuel-efficient Yuchai engine ensures lower long-term operating costs than competing models.

6. Operation and Maintenance
6.1 Standard Operation Specifications
Before daily operation, fully inspect the working status of the 200HP Yuchai engine, check the sealing and operating performance of the hydraulic system, and verify the flexible rotation of the manganese steel mixing drum. During full-load transportation and mountain climbing, maintain a stable drum speed within 0–14rpm to ensure uniform concrete mixing quality. When driving on narrow rural roads and restricted-height sites, control the driving speed reasonably and utilize the flexible steering performance to avoid collision and scratching. Adjust the hydraulic speed according to on-site pouring requirements to ensure smooth discharging and ultra-low concrete residue.
6.2 Daily Maintenance Tips
After each construction operation, thoroughly clean the drum, feeding port and discharging chutes via the 350L stainless steel water washing system to prevent concrete residue caking. Regularly inspect the abrasion condition of the 4mm thick drum barrel, 6mm thick end caps and thickened mixing blades. Check the hydraulic oil quality and system tightness regularly, and replace filter elements on schedule to keep the hydraulic system stable. Inspect the connection firmness of the double-layer frame, 10T rear axle and parabolic suspension parts. Standard daily maintenance can effectively reduce failure rate, maximize the service life of the heavy-duty superstructure and ensure long-term stable operation of the whole vehicle.
