What is right to operate concrete pumping with safe

Concrete Pump 

Concrete pump machinery 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.

Chassis System

Chassis is state switching mechanism for travel and pumping. It have Chassis, PTO system.


Boom System

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

The boom system is used to complete the conveying and distribution of concrete, and support the whole vehicle to ensure stability.


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.


Pumping System

Pumping system is consists of hopper, S valve tube, swing lever, mixing paddle, boom coupler.


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.

Electrical System

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

Classification of concrete pump trucks

With 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.

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.


Concrete pump truck usage limitations.

  • The pumping height is limited by the length of the boom.
  • Construction requires a larger site.
  • Higher requirements for concrete.


The development trend of concrete pump

  • The boom is higher.
  • Increased pumping displacement.
  • Higher degree of automation and intelligence.


How to operate concrete pumping with safe?


  • The safety is always the first when pouring.
  • The concrete pump truck can only be used for concrete delivery and pouring.
  • The concrete pump must be operated in strict accordance with the regulations.
  • It is strictly forbidden to remove any protective device on the concrete pump truck.


Application Security Considerations

  • Do not connect the pipe after the end of the hose.
  • The boom should not be used to lift heavy objects.
  • Modifications to the pump truck that may affect safety are prohibited.
  • Operators must wear safety helmets and comply with safety regulations.
  • The pump truck can only be moved when the boom and outriggers are fully retracted.
  • Follow the direction of the boom pipe when pouring. If there is a place where the pump tube cannot reach, you need to push the concrete pumping hoses.



Concrete Pump Accidents

There are many reasons for the concrete pump accident, it may be your own operation problem, it may be someone else's accidental injury. It can lead to devastating injuries when concrete pump accident. All we can do is to do a good job for the concrete pump maintenance and obey the traffic rules while driving.


Here sharing some concrete pump accidents, everyone must learn lessons, keep in mind with the operation specifications, check the outriggers and the working environment, and always observe the pumping conditions during the operation.
