Electric concrete pump
Electric concrete pump is a modern equipment designed for construction. It drives the pumping system through an electric motor to transport concrete from the mixing plant to the designated location. Compared with the traditional diesel-driven concrete pump truck, the electric concrete pump truck has significant advantages, which are not only reflected in environmental performance, but also in operating efficiency, maintenance cost and other aspects.
Definition of electric concrete pump
What is an electric concrete pump? An electric concrete pump is a concrete delivery device that uses electricity as its main power source. It mainly delivers concrete from a mixing station to the pouring site of a building through a pipeline. Electric concrete pumps are widely used in projects such as building construction, bridge and tunnel construction.
Electrical concrete pumps integrate pumping, delivery, and material distribution functions into one, and can efficiently and accurately complete the delivery of concrete. Compared with traditional diesel concrete pumps, electric pump trucks use electricity as power, which reduces exhaust emissions and has less impact on the environment, and is more in line with the requirements of green buildings and sustainable development currently advocated by the world.
Electric concrete pump model naming rules
Letter part “HBT”:
H: stands for hydraulic drive (Hydraulic);
B: stands for pumping (Beton/Pump);
T: stands for trailer-mounted or fixed.
Number part (such as 20, 30, etc.):
Usually represents the theoretical pumping capacity, the unit is m³/h (cubic meters/hour). For example, HBT-20 means the theoretical pumping capacity is about 20 m³/h.
Note: Some manufacturers may use the maximum outlet pressure (MPa) or motor power (kW) as a reference.
Features of electric concrete pumps
1. Environmental protection and energy saving: Electric pump trucks are powered by electricity and do not require fuel. Compared with diesel engines, they can significantly reduce the emission of carbon dioxide and other harmful gases, which helps to reduce the carbon footprint of construction projects.
2. Convenient operation: Electric pump trucks are usually equipped with intelligent control systems, which are easier to operate and reduce the technical requirements for operators.
3. Low noise: The noise generated by electric pump trucks during operation is relatively low, which is conducive to improving the working environment on the construction site.
4. Low maintenance cost: The operation and maintenance costs of electric pump trucks are relatively low because the wear of electric drive components is usually lower than that of fuel drive components.
5. Strong adaptability: Electric pump trucks can be flexibly applied to various types of construction sites, including urban centers, residential areas and other areas with high requirements for noise and pollution control
6. Suitable for high-rise buildings: Due to the good vertical conveying capacity of electric pumps, they are particularly suitable for high-rise buildings and long-distance conveying
7. Compact structure: small size, easy to move and operate inside the construction site.
8. Reduce material waste: Due to precise control, there is almost no concrete loss during pumping.

How does an electric concrete pump work?
The working principle of an electric concrete pump is to use a motor to drive the hydraulic system, and the pressure oil of the hydraulic system pushes the piston to do reciprocating motion to achieve the suction and discharge of concrete. The specific process is as follows:
When the pressure oil of the hydraulic system enters the main oil cylinder, the piston rod extends, and at the same time, the pressure oil of the sealing circuit connecting pipe causes the other piston rod to retract.
When the concrete delivery piston connected to the piston rod of the main oil cylinder retracts, a self-priming effect is generated in the delivery cylinder, and the concrete in the hopper is sucked into the delivery cylinder through the suction port of the sliding valve under the action of atmospheric pressure and the boost of the mixing blades.
At the same time, under the action of oil pressure, the piston rod of the other main oil cylinder is pushed out and the concrete piston is pushed out of the delivery cylinder at the same time, and enters the concrete delivery pipe through the Y-shaped pipe of the sliding valve delivery port.
After the action is completed, the system automatically reverses to allow the pressure oil to enter the other main oil cylinder, completing another suction and delivery stroke of different delivery cylinders. This process is repeated repeatedly, and the concrete in the hopper is continuously sucked in and pressed out of the delivery cylinder, reaching the operating point through the pipe connected to the Y-tube and the outlet, completing the pumping operation.
Market prospects of electric concrete pumps
According to SMAT‘s market research online analysis, with the increasing global awareness of environmental protection and the increasing demand for green buildings, the market demand for electric concrete pump trucks is gradually growing.
