Fitted with an independent auxiliary diesel engine, this mixer semi-trailer can keep the mixing drum rotating steadily after being disconnected from the tractor. No requirement for tractor PTO device, compatible with all common towing vehicles. High-strength wear-resistant mixing tank guarantees concrete quality during transit. Three heavy-duty axles and durable frame deliver outstanding road adaptability, widely applied in overseas infrastructure, road and building construction projects.
This self-powered concrete mixer semi-trailer is equipped with an externally mounted independent auxiliary diesel engine drive system. The standalone power unit drives the mixing drum directly via the hydraulic system, allowing the drum to keep rotating continuously even after the semi-trailer is unhitched from the tractor. This prevents concrete segregation, solidification and waste during on-site waiting, multi-site transfer and long-distance transportation, making it ideal for overseas infrastructure projects where customers have a mixed fleet of outdated tractors without PTO power take-off function.
The mixing drum is fabricated from high-strength wear-resistant steel plates with fully automatic submerged arc welding technology, featuring excellent structural rigidity, strong torsional resistance and a long service life. Fitted with a heavy-duty box-type main beam frame, three heavy-load axles and a complete reliable air brake system, the vehicle delivers stable driving performance and safe transportation under complicated road conditions.
Standard full accessories include feeding hopper, discharge chute, maintenance ladder, safety guardrail, hydraulic cooling assembly and protective housing for the independent engine. Core hydraulic and electrical components are sourced from world-famous brands, resulting in a low failure rate and easy routine maintenance.
