Concrete pump truck selection should be based on the object of concrete works, the characteristics of the maximum delivery requirements, the maximum transmission distance, concrete building plans, concrete pump forms and specific conditions of line comprehensive consideration. The type and structure of the concrete pump performance varies with different models, in addition to taking into account the type of concrete pouring on top of the addition, but also consider the type of construction and structure, construction technology requirements, site conditions and the surrounding environment. Usually the main performance parameters of concrete pump should be consistent with the construction needs or slightly larger, if the capacity is too large, the utilization rate is low; too small, not only can not meet the construction requirements but also accelerate the loss of concrete pump truck. Construction adaptability As the concrete pump truck has the advantage of flexibility, and the higher the height of the boom, the higher the pouring height and the larger the cloth radius, the stronger the construction adaptability. In the construction, the high-boom concrete pump truck should be used as far as possible. Boom length of 28 ~ 36m concrete pump truck is a large volume of products on the market, accounting for about 75%. Long arm concrete pump truck will be the construction of the main models. In addition, the concrete pump truck is limited by the carrying capacity of the automobile chassis, the cost increases greatly when the height of the boom exceeds 42m, and is limited by the construction site space. Therefore, it is seldom used. The amount of concrete pump used in construction traffic can be calculated according to the amount of concrete pouring, the actual delivery volume of single machine and the construction operation time. For those one-time concrete pouring large amount of concrete pumping construction, in addition to the calculation to determine, there should be some reserve. In addition, an annual output of 10 to 150,000 m3 of concrete mixing plant, to be equipped with 2 to 3 concrete pump truck. Product Configuration Concrete pump truck product performance in the selection should adhere to a high starting point. If the use of high value on the pump on the concrete, the standard requirements of their products must also be increased. The quality of the main components of the product, from the intrinsic quality to the appearance of the quality should be compatible with the high value of the vehicle. Power system Concrete pump truck with full hydraulic technology, so to consider whether the hydraulic technology used is advanced, how the quality of hydraulic components due to their power from the engine, so in addition to consider the engine performance and quality, but also consider the performance of the car chassis, carrying capacity And quality and so on. Operating system Concrete pump truck operation control system with manual, wired and wireless control, easy and flexible wired control, wireless remote control can be long-distance operation, once the circuit fails, manual operation can be used. After-sales service Concrete pump truck as a special vehicle, because of its special features, safety, mechanical properties, manufacturers of after-sales service and spare parts supply should be requested. Otherwise, once it happens, it will not only affect the progress of construction, but also will produce unimaginable consequences.
