What Are the Different Types of Concrete Mixer Trucks?

Concrete mixer trucks come in various types to meet different construction needs. These trucks can be classified based on the mixing method, unloading method, and driving mode. Understanding these types helps in selecting the right mixer truck for specific job site requirements.

 

 

Dry Mix Concrete Trucks: These trucks carry the raw materials (cement, sand, gravel) separately and mix them with water just before pouring. This method is ideal for long-distance transport or when on-site mixing is preferred.

Wet Mix Concrete Trucks: These trucks carry pre-mixed concrete from a batching plant. The mixing is completed before transport, and the drum rotates to prevent the concrete from setting during transit.

Front Discharge Mixer Trucks: These have the discharge chute at the front of the vehicle, allowing the driver to control the pouring direction easily from inside the cab. This type is popular in North America and suitable for tight job sites.

Rear Discharge Mixer Trucks: The more common type, with the discharge chute located at the rear. These require a spotter or second person to help guide the pour.

External Diesel Engine Power: These mixer trucks use a separate diesel engine to power the drum rotation system.

Chassis Engine Power: The drum is powered by the same engine that drives the truck’s chassis, typically using a power take-off (PTO) system.

Common Chassis Drive Configurations:

6×4: Three axles, with power going to two of them (suitable for medium loads).

8×4: Four axles, with power to two (ideal for heavier loads and better stability).

By understanding the different types of concrete mixer trucks, construction teams can choose the right vehicle for efficiency, productivity, and job-specific needs.
