Application scenarios selected for this model.
The supplied sheet states a 4 m³ drum capacity but does not state a separate concrete yield per batch. The page therefore does not treat 4 m³ as verified batch output.
The drum swing angle is listed as 270°. Chute swing is at least 60°, with hydraulic chute-angle control.
The source sheet lists computer-controlled weighing and C15, C20, C25 and C30 concrete grade settings.
The verified gradeability is 30%. This is a percentage value and is not presented as an angle.
The specification lists a 92 kW Yunnei YN48GBZ engine, high-range speed of 0–25 km/h and low-range speed of 0–9 km/h.
The listed dimensions are 7,700 × 2,580 × 3,450 mm, and the operating weight is 8,300 kg.
