Benefits of technology

[0021]The arrangement manner can fully take advantage of spaces on two sides of the first boom, that is, fully take advantage of the space in a width direction of the vehicle body, so as to facilitate compact arrangement of adjacent column booms, thereby increasing the utilization rate of the transverse space of the vehicle, and facilitating arrangement of more column booms.
[0022]According to the another embodiment of the invention, the boom apparatus includes at least four booms, where each of the third boom and the fourth b

Problems solved by technology

Currently, when the length of the booms needs to be increased, due to the limit of the overall length of the concrete pump vehicle, the length of a single boom cannot be increased unlimitedly.
It is currently adapted that boom sections are directly added to the fourth boom, which can make the overall height of the booms increased, and however is not co
