The safety accident rate of truck mounted boom pump is the highest probability in construction machinery, so what should pay attention to in the purchase process?
1. The type and structure of the building, site conditions and surrounding environment are all prerequisites for deciding to purchase a boom pump truck model.
Many of the accidents caused by the imbalance of the boom pump truck are related to the mismatch between the foundation, the site conditions and the bearing capacity of the purchased model. There are many types of boom pump truck, and the length of the boom and its bearing capacity are completely different. At the same time, the amount of concrete pouring must also be calculated clearly, and the relevant performance parameters must be confirmed with the concrete machinery manufacturer when purchasing.

2. Construction adaptability
The higher the boom height of the boom pump truck, the larger the pouring height and the distribution radius, and the stronger the construction adaptability. Therefore, the selection of a high boom pump truck in construction can expand the adaptability of the pump truck. The boom is a bit wasteful if it is too long, and the concrete cannot be transported to the designated construction point if it is too short. Therefore, within people’s own budget, it is the good way to choose a longer boom pump truck.

At the same time, since the boom of the pump truck cannot be in a vertical or horizontal state, should try to choose a boom that is longer than the construction range for the length of the boom of the pump truck.
3. The boom pump truck pumps the concrete volume per hour
This determines the working speed of a pump truck. It is certain that most engineers want to finish the concrete as soon as possible. Therefore, the theoretical pumping volume of the pump truck needs to be clarified. However, for the calibration of theoretical pumping The square volume is 120m³/hour. In fact, this is the data obtained under the most severe conditions in the laboratory. Therefore, the actual pumping volume per unit time must be smaller than this. The actual pumping volume when the pump truck is working is the same as The pumping concrete pressure is inversely proportional, which mainly depends on the constant power point of the pumping system, the working state of the placing boom, and the unavoidable downtime and intermittent time in actual engineering construction.

4、choose the right price of the pump chassis
At present, the main chassis of concrete pump trucks in China are still mainly imported vehicles, such as Mercedes-Benz, Isuzu and other foreign brands. These brands have certain technical advantages in chassis and engines, which can ensure the long-term and stable working requirements of the pump truck. Therefore, If the budget is suitable, people can try to choose an imported site pump truck. At the same time, it is also recommended to choose an imported site for a long boom pump truck.
5、Boom pump truck spare parts and after-sales service
The boom pump truck is mainly composed of hydraulic system, electrical system and some frame components, among which thousands of spare parts can be used. Imported parts are definitely more stable in performance, and domestic parts are definitely more cost-effective. Therefore, in When choosing, people should weigh the pros and cons by themselves. However, for the pump truck with long boom, it is recommended to use the pump truck model with imported parts.
At the same time, after-sales service is also an important factor to consider when buying a boom pump truck. Good after-sales service can save them a lot of trouble. At the same time, the versatility of accessories is better, and they can find corresponding substitutes in the market.
Summary: In fact, from the above points, it is not so difficult to buy a pump truck. At the same time, it is necessary to consider the difficulty of operation of the boom pump truck. At the same time, pay attention to the relationship between some relevant theoretical parameters and actual parameters. It is helpful for everyone.
