What is the hose of a concrete pump truck?

In the delivery system of concrete pumps, the hose is an indispensable key component, which bears the task of connecting the pump boom and the pouring point as the “last link”. As a supplier of concrete pump fittings, we know that the quality of hose directly affects the construction efficiency and safety.

First, the function and importance of concrete pump truck hose
Concrete pump truck hose is usually installed at the end of the boom, used to flexibly transport concrete to the pouring position. Its core role includes:
Flexible connection: make up for the blind spot that cannot be covered by the rigid pipe of the boom, and adapt to the complex construction environment (e.g. high altitude, narrow space).
Shock absorption and buffer: Reduce the impact of concrete pulses during pumping to protect the boom structure.
Abrasion and pressure resistance: withstand high pressure pumping (usually need to withstand 10-30MPa pressure) and long-term friction of aggregate in concrete.

Second, the structure and material of concrete pump truck hose
High-quality hose adopts multi-layer composite design, common structure includes:
Lining layer: highly wear-resistant rubber or polyurethane material, direct contact with concrete, resistance to aggregate abrasion.
Reinforcement layer: multi-layer steel wire braiding or winding, providing compressive strength and preventing pipe burst.
Outer rubber layer: weather-resistant rubber, anti-UV, anti-oil, adapt to the harsh outdoor environment.
According to different working conditions, the hose can be divided into ordinary type (short distance low pressure pumping) and heavy duty (high pressure, long distance or high intensity construction), the length is usually 0.5-3 meters, and the caliber matches with the hard hose (e.g. 125mm, 150mm).

Third, the concrete pump truck hose selection and maintenance recommendations
Matching conditions: high-pressure pumping need to choose more layers of steel wire, high burst pressure models; corrosive environments need to focus on the outer layer of anti-aging properties.
Regular inspection: found that the inner layer wear dewire, bulging or cracks need to be replaced immediately to avoid construction interruption or safety accidents.
Correct installation: avoid bending radius too small or twisted, and ensure that the hose and hard pipe flange are tightly fixed to prevent leakage during installation.

Concrete pump truck hose is a small part, but it is the key to ensure smooth construction. Choosing reliable suppliers and suitable products can significantly reduce the risk of downtime and extend equipment life.
