Product Description:

Product Description:

A concrete pump is a machine used for transferring liquid concrete by pumping. It is known as a trailer-mounted boom concrete pump because it uses a remote-controlled articulating roboticarm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom. They are a revolutionary alternative to truck-mounted concrete pumps.

Main Product Features:

  1. Chassis:This truck-mounted concrete pump adopts BENZ chassis.

  2. Introduce flexible control when boom is started, rotated and stoped, this reduces the impact and vibration for the boom ,which make the whole machine work more steady, reliable and safe. 

  3. Wide placing range: the 38X-5RZ placing boom’s horizontal radius is 34m, and the maximum vertical reach is38m.

  4. The pumping unit optimize design by ZOOMLION: when the suction area and stroke have increased,it can make the suction efficiency achieve to over 80% of the academic numerical value and higher 10%-15% than trade.

  5. Safety control technology for chassis and driving operation:  it ensure power system (chassis and PTO) to working safely without fault, and extend life of machine; the technology is most reliable and safest in the industry.

Q:What is the difference between concrete conveyors and concrete conveyors?
Under normal circumstances, the concrete pump delivery distance, along the horizontal direction can reach 200 ~ 300m, up to 100m in the vertical direction
Q:What is the difference between a concrete pump and a concrete pump?
The use of pressure to transport the concrete along the pipeline. By the pump and the composition of the pipeline. According to the structure is divided into piston type, squeeze type, water pressure diaphragm type. The pump body installed in the car chassis, and then equipped with retractable or inflected cloth rod, the composition of the pump.
Q:What is the treatment of concrete pump block
After pumping the finished concrete, be sure to use high pressure water to pump and S tube rinse.
Q:What are the drawbacks of concrete pump gate valve and S pipe valve?
The seal of the gate valve is limited by the structure and the sealing pressure is low. In the construction, it is inevitable to use the Y-shaped pipe to connect the double cylinder and the conveying pipe of the concrete pump, and the Y-tube will produce a large pressure loss.
Q:What is the cause of concrete pump blockage?
To identify the clogging site, with a mallet to plug the concrete mixture at the plug, and then through the concrete pump is anti-pump to eliminate the block.
Q:What are the standards for the use of concrete pumps?
The operator (the pump of the concrete pump) shall record the operation of the concrete pump as required.
Q:Whether the concrete pump can pass the height of 3.75 meters
The use of pressure to transport the concrete along the pipeline.
Q:How wide concrete pump truck four support steel feet stretch ?
Different types of pump, such as arm length 30 meters, 48 meters, 52 meters of the pump
Q:Why concrete pump down to play always block the tube
do not for the convenience of the construction to enlarge the slump, down to fight the concrete The greater the slump, the easier it is to block
Q:What are the advantages of concrete pump gate valve and S pipe valve?
Simple structure, smooth flow channel, low flow resistance of concrete; high pumping pressure; hopper from the ground height is low, easy to mix concrete truck to the hopper discharge; for the speed of fast, low noise.
