What is the primary difference between an agitator truck and a concrete mixer truck?
The primary difference lies in their intended function and operational capabilities. An agitator truck is designed to maintain and transport pre-mixed materials, keeping them in proper condition during delivery through continuous low-speed agitation. The Texas Department of Transportation clarifies that “True agitator trucks are sometimes used on TxDOT projects. Agitator trucks can be used to deliver agitated concrete to the project, but never to mix concrete”[5]. In contrast, concrete mixer trucks are designed to actually mix raw ingredients during transport, combining cement, aggregate, and water to create fresh concrete. Agitator trucks receive already-mixed materials and simply maintain their consistency, while mixer trucks perform the actual mixing process. This fundamental difference affects equipment design, capacity ratings, and operational procedures in construction and mining applications.
What are the typical capacity ranges for different types of agitator trucks?
Agitator truck capacities vary significantly based on design configuration and intended applications. Standard agitator trucks can handle maximum capacities of 25 tonnes[1], while typical concrete agitator trucks range from 8 to 12 cubic meters[2]. Semi-agitator configurations offer enhanced capacity, with maximum loads reaching 11.5 m³ depending on state regulations[3]. For comparison, standard rigid concrete trucks are limited to 7.5 m³ maximum loads[3]. These capacity differences significantly impact project planning and delivery efficiency, with larger capacity units reducing the number of trips required while smaller units offering better maneuverability in confined spaces. The choice between different capacity ranges depends on project requirements, site access limitations, and regulatory restrictions in specific jurisdictions.
