Concrete mixer trucks serve as essential transport machinery for concrete plants or mixing stations, linking these facilities to numerous construction sites. When used in conjunction with concrete pumps to perform "relay" delivery at the construction site, they eliminate the need for manual intermediate handling, enabling continuous concrete delivery directly to the pouring point.

Mixer Truck Structure: Consists of a heavy-duty truck chassis and specialized equipment including a power take-off unit, hydraulic system, reduction gearbox, mixing drum, control mechanism, and cleaning system.

• By Chassis: Self-propelled (standard heavy-duty chassis) and trailer-mounted.
• By Transmission: Mechanically driven, fully hydraulic, and mechanical-hydraulic models.
• By Capacity: Small (below 3 m³), Medium (3–8 m³), and Large (above 8 m³). The 6 m³ capacity is the most widely used.
