Product
Concrete trailer pump for sale is a kind of S-tube valve drag pump, and the conveying aggregate size is 40mm. The equipment is mainly used for concrete construction of railways, highway tunnels, bridges and culverts, hydropower, mines, high-rise buildings and other projects.
It greatly improves the construction efficiency of engineering buildings, saves labor costs, shortens the construction period, and expands economic benefits.
In order to meet different engineering needs, we has developed a variety of concrete pump trailers to provide customers with diversified choices.
Electric Type and Diesel Type: According to the power, it can be divided into electric drag pump and diesel drag pump.
Small and Large: According to the pumping capacity, it can be divided into 30 pumps, 40 pumps, 60 pumps, 80 pumps, 90 pumps, etc. As the name suggests, it pumps 30-90 cubic meters per hour. Among them, the small mini drag pumps 30 pumps and 40 pumps are more suitable for small and medium-sized projects such as rural housing construction.
Fine Stone Pumping Machine and Large Aggregate Pumps: According to the diameter of pumped aggregate, it can be divided into fine stone pump and large aggregate pump. The fine stone pump can pump the maximum particle size of aggregate ≤30mm. The large aggregate pump can pump the maximum aggregate particle size ≤ 40mm.
Special Used Trailer Concrete Pump: According to the usage scenarios, trailer mounted concrete pump can also be divided into special pumps for tunnels, special pumps for high-speed bridges, etc.
Working Principle
Power Conversion
When generator or diesel engine starts, the power source will drive the main hydraulic pump. And the main hydraulic pump pressurizes hydraulic oil to create the energy needed for the pumping.
Concrete Delivery
The pressurized oil drives the hydraulic cylinder assembly. When the piston rod extends, it pushes the concrete cylinder piston forward. It forces concrete into the delivery pipeline. At the same time, the alternating action between the distribution valve and main cylinders creates a continuous flow: When one cylinder retracts, it draws fresh concrete from the hopper. While the other extends, pushing concrete into the pipeline. This synchronized cycle ensures non-stop material flow.
Precise material placement
Finally, it will pump the concrete to the pouring site through the conveying pipeline horizontally and vertically.
The trailer concrete pump is built with high-quality components for superior reliability, featuring optimized hydraulic and pumping systems to achieve maximum efficiency. It adopts wear-resistant materials to ensure a longer service life and is equipped with intelligent control systems for precise and stable operation.
Advantages
It is equipped with special pipeline.
It can continuously complete horizontal and vertical conveyance of concrete along pipeline.
It is an ideal kind of existing concrete conveyance equipment.
It combines the production of ready-mixed concrete with pumping construction and uses coagulation.
The soil mixing truck carries out intermediate operation, which can realize continuous pumping and pouring of concrete.
It is used for conveying concrete in large concrete projects.
