Main Components Of A Concrete Pump Trailer
Main Components Of A Concrete Pump Trailer
Pumping system
The pumping system is responsible for providing the required power for the entire system. It is mainly composed of hydraulic pumps, plunger pumps, pumping cylinders, pistons and valves. The reciprocating motion of the concrete piston in the cylinder and the swing of the distribution valve realize the continuous pumping of concrete.
Power system
The power system includes an engine and a hydraulic system. The engine provides power for the pumping system. The hydraulic system includes components such as hydraulic oil tanks, hydraulic pumps, hydraulic pipelines and radiators, which provide power and control for trailer concrete pumps.
Electronic control system
The electronic control system includes a control panel and a remote control system, which are mainly composed of operating elements, sensors, remote controls, and electric control cabinets. The operator controls the operation of the entire pumping system through the control panel to ensure safe and efficient work.
Chassis and traction system
The concrete trailer pump uses a trailer chassis, which is mainly composed of a car chassis, an engine, a transfer case and a drive system, etc., to support and transport the entire pumping system. The traction device connects the concrete pump to the vehicle to ensure stable movement of the equipment.
Safety system
The trailer mounted concrete pump safety system includes a pressure protection device, a sensor and an alarm system, which will automatically alarm when an abnormality is found. Overload protection and automatic shutdown functions avoid damage caused by overload work and ensure the long-term stability of the equipment.
How Does A Concrete Pump Machine Work?
The trailer mounted concrete pump mainly relies on the pressure of the oil cylinder. The mixed concrete is poured into the hopper by a mixing truck or a pump truck. Driven by the oil cylinder, the two pistons in the delivery cylinder on the hopper wall alternately reciprocate to achieve the suction and push of the concrete. When the piston retreats, the concrete is sucked into the cylinder; when the piston pushes forward, the piston pushes the concrete into the S-type distribution valve between the two cylinder heads, and moves left and right in a sequential motion through the hydraulic swing valve cylinder and electrical control, and is transported to the designated location of the construction site through the delivery pipeline.
The main working process of the cement pump trailer is five steps: feeding, suction, pumping, discharging, and cleaning. It relies on the coordinated work of the hydraulic system and the plunger pump. The reciprocating motion of the piston is used to achieve the suction and pumping of the concrete. The pumping pressure is adjusted by the pressure sensor and valve to ensure that the concrete is smoothly and stably transported through the pipeline. This efficient and convenient delivery method can greatly improve the construction efficiency and ensure the continuity and stability of the concrete.
Advantages of A Portable Concrete Pump
High Efficiency
Adopts 3-pump 3-circuit hydraulic system, with less impact and higher reliability. It has reverse pump function, which helps to remove the blockage of clogged pipes in a timely manner and can be stopped in a short time. It can transport concrete continuously and quickly, which greatly improves construction efficiency.
Strong Adaptability
The concrete pump trailer has strong adaptability to the construction work surface and can be installed in hard-to-reach places such as high-rise buildings, basements, etc. to meet various construction needs. By using serial pumps, the output distance can be extended to meet the needs of long-distance pumping.
Energy-Saving
The portable trailer concrete pump is continuous, which reduces the waste of concrete during transportation and waiting, and improves the utilization rate of materials. It also reduces a lot of labor when using, which reduces labor costs. The user-friendly design makes operation more convenient and maintenance easier.
High Configuration Design
Equipped with high-performance hydraulic systems, these systems provide smooth and powerful power to ensure continuous and stable concrete supply. The efficient hydraulic system reduces energy consumption and improves the efficiency of the concrete pumping machine. The dual piston pump provides larger displacement and higher pressure.
Easy To Maintain
Adopting wear-resistant alloy spectacle plate and floating cutting ring, it extends the service life of the main components. Automatic centralized lubrication system and easy-to-clean hopper design reduce the difficulty and cost of daily maintenance.
Electric Concrete Pump VS Diesel Concrete Pump
| Feature | Electric Concrete Pump trailer | Diesel Concrete Pump trailer |
| Power Source | Electric motor | Diesel engine |
| Fuel Efficiency | Requires electricity | Runs on diesel, can be used in remote areas without electricity |
| Noise Level | Quieter operation | Noisier due to engine operation |
| Operational Cost | Lower operational cost | Higher fuel cost |
| Mobility | Limited to locations with a stable power source | Can operate in remote locations without power supply |
| Installation | Easier installation | Requires more complex setup |
| Size and Weight | Typically smaller and lighter | Typically heavier due to the engine and fuel tank |
| Cost | less expensive upfront | Higher initial cost |
How Much Is A Portable Concrete Pump Trailer?
Concrete drag pumps can deliver concrete quickly and continuously through mechanized operations. Compared with traditional manual transportation, they greatly improve the construction speed and avoid the problems of concrete stratification and segregation caused by improper manual operation. With strong pumping capacity and stable performance, the quality of the project is further guaranteed.
The trailer concrete pump price varies depending on many factors such as brand, model, configuration, performance, and market supply and demand. According to the pumping capacity, the greater the pumping capacity per hour, the higher the price; according to the engine type, the diesel engine has strong power and relatively high price, and it can be used in construction environments without power supply; the electric engine has a relatively low price and is suitable for construction sites with stable power supply.
| Model | Price |
| EHBT (Electric-motor Driven) | $16,000-$30,000 |
| DHBT (Diesel-engine Driven) | $20,000-$40,000 |
