The machine is equipped with a Yuchai 4108 turbocharged diesel engine with 91kW power.
This engine configuration supports loading, driving, mixing, and discharge work in construction-site conditions. The provided engine information also includes a direct-injection reduced-bore W-type combustion chamber, vertical inline water cooling, and four-stroke structure, helping the concrete mixer machine maintain stable performance during daily operation.
The mixing drum uses manganese steel material and is supported by four drum rollers for improved drum stability.
This structure supports onsite concrete mixing, transportation, and discharge. For buyers who need a mobile concrete solution for construction projects, the drum system helps combine mixing and movement into one machine, reducing the need for separate concrete mixing equipment in suitable working conditions.
The machine is equipped with a fully sealed ductile cast steel turntable, designed to support stable rotation and reliable structural strength during loading, mixing, turning, and discharge operations.
The sealed structure helps protect the turntable system from dust, sand, water, and jobsite debris, making it more suitable for demanding construction environments. This turntable design helps improve operating stability, rotation reliability, and long-term durability during frequent concrete unloading.
The machine is equipped with automatic water metering, a full hydraulic external water suction pump, two water supply systems, and a secondary water supply system.
Automatic water metering helps improve batching consistency and reduce manual water-control errors. The hydraulic water suction system supports water intake under different jobsite conditions, making the machine practical for road work, rural construction, and remote projects where fixed water supply may not always be convenient.
The machine uses a dual wheel-side dual-brake reduction axle, Ruili brake master cylinder, wheel cylinder and hand brake pump, and a brake system with dryer treatment.
It is also equipped with Chaoyang tires and dual front wheels, supporting jobsite movement and load-bearing needs. These components help the concrete truck move more steadily across construction sites, rural roads, and uneven working areas.
The machine uses a genuine excavator-style cab, heating and cooling air conditioning, a large automotive seat, and a driving camera to support easier operation during long working hours.
It also includes a bucket vibrator, dual hydraulic cooling system, secondary air treatment filter, and automatic hydraulic chute. These systems support daily concrete handling, operation comfort, cooling, air treatment, discharge convenience, and jobsite working efficiency.
Engineered for adaptability, our self-loading concrete mixers deliver high-quality concrete exactly where you need it, overcoming the limitations of traditional batching plants
