3.0m³ Large-Capacity Mixing Drum
Searching for "3 ton self-loading concrete mixer" or "high-capacity mobile batching plant"? The SZJ30 features a 3.0m³ mixing drum with 3200mm discharge height—producing more concrete per batch for larger projects. Perfect for bridges, dams, and commercial construction sites requiring high-volume output.
YUCHAI 85KW Power & 4x4 Traction
Powered by a reliable YUCHAI 4-cylinder water-cooled diesel engine with 4x4 drive and 40° gradeability, this machine conquers steep terrain and muddy sites effortlessly. Massive 16/70 R22.5 tires ensure traction anywhere, anytime.
Complete On-Site Concrete Factory
With 640L water tank, 40km/h travel speed, and 8700kg operating weight, it loads, mixes, transports, and discharges seamlessly—eliminating separate loaders, mixers, and trucks while delivering 40 batches per day.
Detailed Advantage Breakdown
High-Volume Production for Demanding Projects
The SZJ30 is engineered for projects where concrete demand outpaces smaller machines. Its 3.0m³ mixing drum produces 40-50 batches per day—equivalent to 120-150m³ of fresh concrete daily. The 3200mm discharge height allows direct placement into high-sided trucks, deep foundation forms, or elevated slab structures. This capacity makes it ideal for bridge construction, dam projects, commercial developments, and large-scale infrastructure where consistent concrete supply is critical to maintaining schedule.
YUCHAI Power Backed by Global Reputation
The 85KW YUCHAI 4-cylinder water-cooled diesel engine is trusted worldwide for its durability, fuel efficiency, and ease of maintenance. In remote project locations where service access is limited, YUCHAI's reliability becomes invaluable. The engine delivers peak torque at low RPMs, ensuring powerful performance during mixing and climbing without excessive fuel consumption. Combined with 4x4 drive and 40° gradeability, this machine accesses the toughest job sites—from mountain road construction to riverside foundation work.
Superior Mobility and Site Access
With 40km/h travel speed and massive 16/70 R22.5 tires, the SZJ30 moves quickly between project phases and tackles rough terrain that stops standard trucks. The 8700kg operating weight provides stability during transport and mixing, while the 7900×2800×3070mm dimensions remain road-legal in most regions. The articulated steering delivers a tight turning radius, allowing precise positioning in confined urban sites and narrow access roads common in infrastructure projects.
Operator-Focused Productivity
The spacious cab features intuitive hydraulic controls that allow one operator to manage the entire concrete production process—from loading aggregates with the hydraulically operated bucket to precise water measurement from the 640L tank, mixing, and discharging. The elevated cab position provides panoramic visibility to the loading area, mixing drum, and discharge point, enhancing safety and accuracy. Digital displays provide real-time feedback on mix counts, water usage, and system status.
Built for Long-Term Reliability
The 3.0m³ mixing drum features reinforced wear-resistant liners extending service life under continuous operation. Heavy-duty axles and drivetrain components withstand the stresses of off-road travel and daily mixing cycles. The 640L water tank includes a high-pressure cleaning system for maintaining the drum and discharge chute. Strategic maintenance access points simplify daily checks—fluid levels, filters, and lubrication points are easily reached without specialized tools. Backed by SAAO's 20 years of manufacturing expertise and 2-year warranty, the SZJ30 delivers the reliability global contractors demand for large-scale infrastructure projects.
