Advantages of the Concrete Pumping Trailer

1. Reliable Performance

Concrete trailer pump simplifies construction process while providing greater accuracy on the project. And it will always provide you with an accessible and reliable experience.

  • The highly automatic lubrication system can ensure that the hydraulic pressure oil is conveyed to various parts during the operation of the machine.
  • Concrete trailer pump adopts double-pump and dual loop open hydraulic system, and the main pumping channel for conveying oil and the swinging oil channel of the S-shaped valve are independent of each other, which makes it easy to operate the machine and extends the service life.
  • The concrete trailer pump has the anti-pumping function, which is convenient to deal with the pipeline fault and makes it available to machine halt and materials waiting for a short time.

2. High Quality

  • The concrete trailer pump adopts the advanced S-shaped distribution valve that can compensate wear clearance automatically, and it has good seal-ability.
  • Wear resistant alloy spectacle plate and floating cutting ring are adopted, which makes the trailer concrete pump have longer service life. The maximum service life of the spectacle plate can reach more than 30000 m3.
  • Automatic centralized lubrication system ensures that the trailer concrete pump can be lubricated effectively during the operation.
  • All parts adopt national standards with good interchangeability.

3. Easy Operation

With the remote controller, people don’t need to operate the machine next to it, so the operation is more safe and convenient.

How Do Concrete Trailer Pumps work?

The high-pressure oil output by the main oil pump is distributed to the main oil cylinder through the sequence valves, which pushes the piston rod of the main oil cylinder back and forth.

Because the piston rod of the main oil cylinder is linked with the piston rod of the concrete cylinder, the piston rod of the concrete cylinder will move backwards and forwards under the push of the high-pressure oil. The suction and extrusion of concrete will be carried out.

Meanwhile, two swing oil cylinders drive the swing arm, which will result in switching of S-shaped valve back and forth between the two concrete cylinder outlets under the influence of the swing arm.

Through the continuous reciprocating motion of the concrete cylinders and switching of S-shaped valve backwards and forwards, the continuous suction and extrusion pressure of concrete can be realized, so as to realize the whole pumping process.

Applications of the Trailer Concrete Pump

Applications of the concrete trailer pump can be found in terms of housing construction, bridge construction, tunnel construction and so on.

Power System of a Concrete Trailer Pump

The electric motor or the diesel engine: is the essential power source, the voltage of which can be customized. And Wei Fang (a city in Shandong province) Delier and Wei Fang Deutz (formerly a joint enterprise,now a domestic brand) are the leading brands in terms of the electric motor or diesel engine throughout China.

Hydraulic System of a Trailer Concrete Pump

Hydraulic system is composed of hydraulic pump, hydraulic oil tank, revising valves, hydraulic oil cylinder or hydraulic motor, cooling system, as well as energy accumulator.

The hydraulic pump

The hydraulic pump is composed of the main oil pump, the heat dissipation oil pump and the mixing oil pump.

  • The main oil pump (piston pump): is the power source of the high-pressure oil to the whole pumping system, and which is also a part of the “cardiac system” of the trailer concrete pump besides the electric motor.
  • The mixing oil pump: provides the hopper mixer with the high-pressure oil as the dynamic impetus.
  • The heat dissipation oil pump: conveys hot oil from the hydraulic oil tank to channels of the heat radiator and then the heat dissipation can be carried out through the blowing of an air fan.

The mixing oil pump and the heat dissipation oil pump are the parts of gear pumps. Despite of different purposes, they works in the same way that the high-pressure oil is supplied by high-speed rotation and extrusion between gears.

The hydraulic oil tank:

The hydraulic oil tank is used to store hydraulic oil that is the medium in which the liquid force is conveyed.

The hydraulic oil port is at the top of the hydraulic oil tank, and the oil is filled up when the trailer concrete pump leaves factory. The whole tank of oil costs about $300.

The revising valves:

It can adjust the pumping state to make the concrete pump continuously operate through the change of the hydraulic oil direction of the main oil cylinder.

The hydraulic oil cylinder or hydraulic motor:

The operating part of the hydraulic system, drives the concrete cylinder pistons, the swing arm and the swing oil tank under the effect of high-pressure oil.

The cooling system:

The cooling system consists of water-cooling system and air-cooling system.

Due to some factors of the hydraulic system, generally the water-cooling system is installed in the trailer concrete pump, of which conveying capacity is 40m3/h and below so as to enhance the heat dissipation, and price is in 3000 yuan or so.

But the common domestic manufacturers don’t use the water-cooling system.

Why cool down the hydraulic oil? As time goes on, the hydraulic oil absorbs heat and increase temperature during the processes of extrusion and release, which will have a negative effect on the service life and efficiency of the hydraulic components.

The energy accumulator:

The energy accumulator has a certain pressure inside itself so that it has an positive effect on the hydraulic components.

The pressure can act as a buffer against the release process of high-pressure oil to extend the service life of the hydraulic components.

The Electronic Control System of a Trailer Concrete Pump

General electric control system adopts PLC controller, some of them even equipped with text display and touch button, has the good man-machine communication interface.

The monitors send signals to PLC controller, PLC controller shows the working state of the concrete pump via text display.

PLC is installed in the electric control cabinet which acts as the brain of the whole concrete pump and gives instructions.

Omron is the well-known international PLC manufacturer, and electric components related to PLC are imported from Schneider which is the leading electric enterprise and one of the world’s Top 500 enterprises.

What is the Maximum Distance Concrete Can be Pumped?

Generally speaking, the maximum horizontal distance that concrete can be pumped is about 1km. And the maximum vertical distance is about 200m.

The motor power of a concrete delivery pump is the precondition of determining the delivery pressure and delivery capacity.

When the motor power is certain, the increase of delivery pressure will reduce the delivery capacity; On the contrary, the decrease of delivery pressure will increase the conveying capacity.

Outlet pressure and delivery capacity are the important components when it comes to machine’s capacity of performing a long-distance pump.

If we want a trailer concrete pump that has both the high outlet pressure and large delivery capacity, the only way we can do is to improve the power of electric engine.

Therefore, the concept of capacity index of the concrete delivery pump is adopted in the new national standard, that is the product of the actual outlet pressure and the delivery capacity per hour.

The larger the product is, the larger the capacity index is, and the larger the power of electric engine is, so as to realize the goal that we want a trailer concrete pump with large delivery capacity and high-lift.

How Do You Transport a Trailer Mounted Concrete Pump?

When it comes to transport of a concrete trailer pump, it’s very necessary to make an introduction of the dragged structure. The specific introduction is as the following pictures:

The axle of a concrete trailer pump belongs to the low-speed axle, which can only be dragged on the site for a short time, not be dragged on the road.

A flat-bed trailer is required for long-distance transport. The landing legs should be lifted to avoid the tyres closing to the ground, otherwise the axle will be damaged due to the vibration of the machine working.

How Heavy Does a Trailer Concrete Pump Weigh?

The weigh of the concrete trailer pump varies each other because of the different models. A trailer concrete pump weighs 6300kg-7600kg.
