The concrete mixer truck is a construction workhorse, featuring a rotating drum to transport and blend concrete. Its design keeps the mix fluid, preventing setting en route. Equipped with robust engines, it ensures timely delivery, making it vital for building sites worldwide.
Axle Configuration:
Concrete mixer trucks typically come with two or more axles — most commonly four, five, or six.
Axle Function:
The number of axles depends on load capacity requirements and local road regulations for heavy vehicles.
Load Distribution:
Multiple axles help distribute weight evenly, reducing road wear and extending the lifespan of both the truck and road surfaces.
Drum Capacity:
Specialized mixer trucks often have drum capacities ranging from 8m³ to 12m³, ideal for medium to large-scale concrete transport.
Hardox Technology:
Some mixers use Hardox steel, offering low weight, superior wear resistance, and higher load capacity, improving overall efficiency and durability.
Core Component – Mixing Drum:
The heart of the truck is its rotating drum, which mixes and transports concrete.
Loading Stage:
Raw materials such as cement, sand, gravel, and water are loaded into the drum.
Mixing During Transport:
The drum rotates slowly (about 1–3 rpm) using a hydraulic system driven by the truck’s engine.
Agitation Blades:
Spiral blades inside the drum continuously turn the mix, preventing hardening and ensuring uniform consistency.
Discharging Concrete:
At the construction site, the drum reverses rotation, guiding the mixed concrete out through a discharge chute.
Efficiency:
This dual-direction design allows on-site delivery of fresh, evenly mixed concrete efficiently and reliably.
