Crawler-type automatic concrete mixer trucks primarily consist of four components: the chassis system, mixing system, power system, and control system.
Chassis System: Features a high-strength tracked structure and a hydraulic drive system, enabling operation across challenging terrains such as mud, sand, gravel, and steep slopes. It typically offers a maximum gradeability exceeding 30° and exerts low ground pressure, thereby minimizing surface damage.
Mixing System: Comprises a mixing drum, feed inlet, discharge outlet, and drive mechanism. Helical blades welded to the inner wall of the drum rotate-driven by an electric motor or hydraulic motor-to ensure thorough, forced mixing of the concrete. Some models utilize twin-shaft mixing technology to further enhance mixing uniformity.
Power System: Typically powered by a diesel engine (ranging from 50 to 200 kW), with some models incorporating an electric auxiliary system to reduce energy consumption. Power is distributed via a transfer case to both the chassis and the mixing system, ensuring coordinated operation.
Control System: Integrates an automated control module that allows for the presetting of mixing times, rotation speeds, and discharge volumes. Certain high-end models support remote monitoring and fault diagnosis, enhancing operational convenience.
