Concrete pump truck structure, working principle and advantages

Structure and Features of Concrete Pump Trucks

Concrete pump trucks consist of a chassis, rotating boom, pumping system, pipeline system, lubrication system, cooling system, and control system. Among these, the pumping system and pipeline system are the core components. The pumping system includes a motor, oil pump, hydraulic system, and discharge pipe. The motor drives the oil pump, and the hydraulic system pushes the concrete into the discharge pipe for delivery. The pipeline system comprises delivery pipes and high-pressure hoses, which transport the concrete to the construction site.

Working Principle of Concrete Pump Trucks

The working principle of a concrete pump truck involves the pumping system extracting concrete from the mixing tank and delivering it through high-pressure pipes and hoses to the construction site. The specific process is as follows:

(1) Extracting Concrete from the Mixing Tank:

The delivery system of the concrete pump truck extracts concrete from the mixing tank. The hydraulic system drives the valve at the inlet, drawing the concrete into the pumping system.

(2) Setting Up the Pipeline at the Ground End:

At the construction site, the delivery pipeline system must be set up and ensure stable transport during construction. Generally, high-pressure rigid pipes with a diameter less than 125 millimeters are more pressure-resistant than hoses and are more commonly used for concrete pumping.

(3) Transporting Concrete to the Construction Site:

As the pumping system operates, the concrete gradually moves through the pipeline to the construction site. Due to the unique properties of concrete, it is crucial to control the pumping speed and flow rate to ensure the quality and progress of the construction.

(4) Completing the Construction Task:

Once the concrete reaches the designated location, the construction task is complete. Throughout the process, the pumping and pipeline systems of the concrete pump truck must ensure sealing and stability, and require timely maintenance to extend the equipment’s lifespan.

Advantages of Concrete Pump Trucks in Construction

Concrete pump trucks offer numerous advantages in construction, as outlined below:

Improved Construction Efficiency:

Concrete pump trucks can directly deliver concrete to the site, avoiding the time and labor waste associated with manual transport, thereby improving construction efficiency.

Reduced Construction Costs:

Since concrete pump trucks do not require manual labor for transport, they can reduce labor costs.

Enhanced Construction Quality:

The concrete transported by the pump truck maintains stable flow and pressure in the pipeline, ensuring that the concrete does not lose uniformity during transport, thus improving construction quality.

Safety and Reliability:

Concrete pump trucks operate without requiring workers to directly handle the concrete, significantly enhancing worker safety.


As a specialized piece of construction machinery, concrete pump trucks play an irreplaceable role in construction projects. This article has explained the working principle and advantages of concrete pump trucks, providing a better understanding of their use and benefits in construction.
