What is Concrete Pump Truck

What Is Concrete Pump? 

Concrete pump machinery truck is a heavy duty construction equipment, which uses hydraulic system to continuously transport concrete through pipelines. The concrete pump truck is mainly composed of chassis, boom system, turret, pumping system, hydraulic system and electrical system.

Concrte Pump Boom System

The boom system consists of multi-section booms, connecting rods, oil cylinders and connecting parts.

The boom system is used for conveying and distributing concrete. Through the telescopic boom oil cylinder and the rotation of the turntable, the concrete is directly delivered to the pouring point by the concrete pumping pipe tube and hoses.

Concrete Pump Turret system

Turret system is consists of turntable, slewing mechanism, fixed turret, support system.

The outrigger arm is designed as a box-shaped beam formed by surrounding welding of four high-strength steel plates. The height changes from large to small according to the size of the force. For the X outrigger, it has the advantages of light weight, small deployment space and fast deployment speed during construction.

Support system safety precautions

The boom must be operated after the outriggers are supported as required.

The outriggers can only be retracted after the boom is folded and placed on the main support of the boom.

In the event of factors that reduce stability, the boom must be retracted immediately.

Concrete Pump Hydralic Pumping System

Hydraulic Pumping system is consists of hopper, S valve tube, swing lever, mixing paddle, boom coupler, pressure gauge and other parts.

The pumping system uses the power of the chassis engine to pressurize the concrete into the pipeline from the hopper, and then the operator controls the boom to send the concrete directly to the pouring point through the pipeline.

Concrete Pump Chassis System

The chassis system of concrete pump truck mainly adopts Mercedes Benz, Volvo, Isuzu, Hino, Mack, SCANNIA, SINOTRUCK etc. 

The chassis part is composed of automobile engine, chassis, transfer case, transmission shaft, etc.

The reliability of the chassis is a crucial link to determine whether the concrete pump truck can work normally for a long time.  As one of the key components of the concrete pump truck, the chassis not only plays the function of transferring and moving the concrete pump truck, but also plays the function of providing power for the concrete pump when it is operating. It also has the function of balancing the stability of the whole vehicle and playing the role of counterweight.

Classification of Concrete Pump

Concrete Pump by folding 

With concrete pump folding type, it usual have R folding, Z folding, Z&R folding.

The R type has a compact structure; the Z boom moves quickly when opening and folding; the Z&R type combines the advantages of the former two and is gradually widely used.

The Z-type, R-type and Z&R types of the boom are mixed and used by different manufacturers.

Concrete Pump type by Boom Placer Length

Short boom concrete pump: Boom length blow 30m.

Normal boom concrete pump: 30m ~ 40m.

Length boom concrete pump: 40m~ 50m.

Overlength boom concrete pump: Over 50m boom length.

Electrical System

The concrete pump electrical system is mainly composed of control cabinet, remote control and other electrical components.


Advantages of concrete pumping

  • The concrete pouring is convenient and fast, the pumping speed is fast, and the work efficiency is high.
  • High degree of automation, equipped with remote control, easy to operate.
  • Good mechanical properties and high equipment utilization.

The development trend of concrete pump


Concrete pump truck is suitable for concrete transportation in urban construction, airports etc.


  • The boom is higher.
  • Increased pumping displacement.
  • Higher degree of automation and intelligence.
  • Whole machine weight reducing.
