With the rapid development of the economy, great changes have taken place in both the city and the countryside. Therefore, the market demand for concrete pump truck is also more and more vigorous. In order to shorten the construction period and reduce the construction cost, most of the constructor uses concrete pump truck to speed up the construction progress. Concrete pump truck for concrete mixing station is of great significance, therefore, it is very important to choose the appropriate concrete pump truck, but face to face, the product of concrete pump truck manufacturers more, I believe many people will suffer from fear of what to choose, how to choose, should pay attention to what?
1., before buying, users can know the quality of the pump car by consulting the identification certificate, type test report, special vehicle inspection report, vehicle directory number and quality system certification certificate.
2., the selection of concrete pump truck should be considered comprehensively according to the maximum distance of concrete engineering objects, characteristics and requirements, concrete building plan, concrete pump form and specific conditions.
3., the performance of concrete pump truck is random and different. When selecting the type of machine, besides considering the amount of concrete pouring, we should also consider the type and structure of the building, the construction technology requirements, the field conditions and the environment. Usually the main performance parameters of the concrete pump truck should be in line with the construction requirements or slightly larger. If the capacity is too large, the utilization rate is low and too small, not only can not meet the requirements, but also speed up the loss of concrete pump cars.
4., the concrete pump truck has the flexibility, the higher the height of the boom, the greater the casting height and the fabric radius, and the stronger the adaptability of the construction. In the construction, we should choose the high arm concrete pump truck as far as possible. The concrete pump truck with the arm length of 28 to 36m is a wide range of products in the market, accounting for about 75%. The long arm concrete pump will be the main model in the construction. In addition, the concrete pump truck is limited by the bearing capacity of the truck chassis. When the boom height exceeds 42m, the cost increases greatly, and is limited by the space of the construction site, so it is seldom selected.
5. the quantity of concrete pump used for construction business can be calculated according to the pouring amount of concrete, the actual amount of the single machine and the time of construction work. In addition to the calculation and determination, there should be a certain amount of reserve for the construction of concrete pumping construction with a large amount of disposable concrete. In addition, the concrete mixing station with a annual output of 10~15 million M3 needs to be equipped with 2~3 concrete pumps.
6. the product performance of the concrete pump car should stick to the high starting point when choosing the type. If the concrete pump truck with high value is selected, the standard requirements for its products need to be improved. The quality of the main components of the product, from the internal quality to the appearance quality, should be adapted to the high value of the vehicle.
7. the concrete pump car adopts all hydraulic technology, so it is necessary to consider whether all the hydraulic technologies are advanced and the quality of the hydraulic vision. In addition to the engine performance and quality, the performance, bearing capacity and quality of the chassis must be considered, as the power of the engine is derived from the engine.
8., the operation control system of concrete pump truck has manual, wired and wireless control methods. The wire control is convenient and flexible, and wireless remote control can operate remotely. Once the circuit is out of order, manual operation mode can be adopted.
