This model is equipped with a Yunnei 490 turbocharged diesel engine rated at 55kW. The turbocharged diesel power system supports stronger working performance for onsite concrete mixing, jobsite movement, and regular construction operation.
Diesel power is practical for outdoor construction, rural road projects, remote jobsites, and areas where stable electric power may not always be available.
The mixer uses a double-cone mixing drum with double-spiral mixing screws and a convex bottom. The drum has a 1700L geometrical capacity and provides approximately 1.2m³ concrete yield per batch.
With a 13 rpm drum rotation speed, the machine supports stable small-batch concrete preparation for foundations, building work, road repair, rural construction, and other onsite concrete applications.
The front loading bucket helps collect sand, gravel, cement, and other raw materials before feeding them into the mixing drum. This design helps reduce dependence on separate loading equipment for many small and medium construction tasks.
The hydraulic feeding structure makes material loading and transfer more convenient, helping contractors use one compact concrete mixer machine for loading, mixing, moving, and unloading work.
The machine uses a torque converter drive form and ZL-265 power shift gearbox with 4 forward and 4 reverse gears. This configuration supports flexible movement, positioning, and repeated operation during loading and unloading.
The torque converter helps provide smoother power transmission under construction working conditions, while the multiple gear options allow the operator to adapt to different site movement needs.
The hydraulic system includes a KY07-2-0 reducer, 50/32 dual gear pump, and cycloid 125 motor. These components support key working actions related to mixing, loading, movement, and unloading.
The machine also uses a compact four-wheel chassis with 280 mm ground clearance and a visible enclosed cab structure. These features support better jobsite mobility, driver visibility, and operating convenience on small and medium construction sites.
The 1.2CBM model is equipped with a 400L water tank and a time relay water supply system. This helps support water filling during onsite concrete mixing and improves operation convenience compared with manual water handling.
For concrete preparation, a practical water supply system helps operators manage the mixing process more efficiently, especially when working on road projects, rural construction sites, and remote jobsites.
Engineered for adaptability, our self-loading concrete mixers deliver high-quality concrete exactly where you need it, overcoming the limitations of traditional batching plants
