1. Product Overview
The
DAYUN 4×2 7.5m³ Concrete Mixer Truck is a high-cost-performance light-duty concrete transportation equipment that perfectly breaks the capacity limitation of traditional small mixer trucks. It creatively equips a large 7.5m³ mixing drum on a mature 4×2 single-axle chassis, realizing a perfect balance of large transportation volume, flexible maneuverability and low overall investment cost, filling the market gap between small 4–5m³ light mixers and heavy 6×4 large mixers.
The vehicle is equipped with full set of factory-standard premium configurations to ensure comfortable and efficient operation. The standard equipment includes factory A/C, power steering, airbag shock-absorbing driver seat, electric windows, remote central lock and panoramic extended mirrors, effectively reducing driver fatigue during frequent short-distance shuttle operations and long working shifts. For global export business, this model supports flexible LHD and RHD steering layout customization, fully adapting to traffic rules and vehicle registration requirements of different countries and regions worldwide.
Adopting a super-short 3600mm wheelbase and a compact total length of 7.65m, the truck boasts ultra-flexible steering and excellent site passing performance. It can easily navigate narrow rural roads and height & width restricted township construction sites that large 6×4 tandem mixers cannot access. Powered by a reliable 200HP Yuchai engine, the powertrain delivers strong low-RPM torque, providing powerful climbing capability for mountainous and complex road conditions. Meanwhile, it achieves 8%–12% lower fuel consumption than competing models, with globally accessible spare parts and complete overseas service network support. The whole vehicle adopts heavy-duty superstructure design, fitted with thickened manganese steel mixing drum for outstanding abrasion resistance and anti-adhesion performance; optional imported hydraulic components ensure excellent sealing performance, uniform concrete mixing and minimal raw material waste.
2. Working Principle
The DAYUN 4×2 7.5m³ concrete mixer truck relies on the low-speed high-torque output of the 200HP Yuchai engine to drive the full hydraulic circulating mixing system. Stable and sufficient power is continuously transmitted to the hydraulic assembly, driving the 7.5m³ thickened manganese steel mixing drum to rotate at stepless adjustable constant speed during transportation.
The high-strength manganese steel drum and optimized internal blade structure effectively avoid concrete segregation, sedimentation and solidification during driving, ensuring fresh and uniform concrete quality upon arrival at construction sites. When equipped with optional imported hydraulic components, the system features tighter sealing, more stable operation and higher mixing accuracy, realizing uniform stirring and smooth discharging with extremely low concrete residue and minimal raw material waste.
The hydraulic system supports forward and reverse rotation and flexible speed regulation to complete automatic feeding, constant stirring and quantitative discharging. The matched circulating water cleaning system can thoroughly flush residual concrete inside the drum and chutes after operation to prevent material caking and equipment blockage. The well-matched Yuchai powertrain maintains stable power output under frequent start-stop and short-cycle working conditions, with low failure rate and strong working stability for long-term continuous construction operations.
3. Daily Application Scenarios
The DAYUN 4×2 7.5m³ large-capacity light-duty mixer truck is widely applicable for medium and small-scale construction projects that require both certain concrete supply capacity and flexible site adaptability. It is perfectly suitable for rural large-area self-built housing, rural road upgrading and paving, township municipal renovation, slope protection engineering, irrigation ditch construction, small precast component processing factories and micro ready-mix concrete stations.
Benefiting from its short wheelbase and compact body size, the truck can freely enter narrow village roads, height-limited construction zones and mountainous working sites inaccessible to heavy 6×4 mixers. It is extremely suitable for short-term leasing business of small and medium engineering teams. With 50% higher transportation capacity than traditional 4–5m³ small mixers, it greatly improves project construction efficiency and is an ideal equipment for grassroots infrastructure construction and engineering fleet rental projects in Southeast Asia, Africa, Central Asia and other emerging markets.
4. Comparison With Traditional Models
Compared with traditional 4–5m³ small light-duty mixer trucks, the DAYUN 7.5m³ model has a 50% higher single-vehicle transportation capacity, effectively reducing delivery frequency, shortening project construction cycles and greatly improving overall working efficiency. It completely solves the pain point of insufficient supply capacity of small mixers for medium-volume concrete projects.
Compared with 6×4 tandem 8–10m³ heavy-duty mixer trucks, this 4×2 single-axle model has a much lower purchase cost, insurance cost, road toll and daily maintenance cost, effectively reducing the initial investment pressure and long-term operating expenditure for fleet investors and small and medium construction enterprises, realizing faster return on investment.
In terms of site adaptability, the 3600mm short wheelbase and 7.65m ultra-compact body enable it to adapt to narrow and restricted construction sites where heavy mixers cannot work, balancing large load capacity and flexible maneuverability. In terms of power and durability, the fuel-saving Yuchai engine has lower comprehensive fuel consumption than competing models with global spare parts support, while the thickened manganese steel drum and optional imported hydraulic parts ensure longer service life and lower material waste rate.
