How to buy concrete pump can not afford pit? These eight tips must understand
As the rapid economic development, both in urban and rural areas have undergone enormous changes. Thus the market demand for concrete pump truck is naturally more and more prosperous, the construction side in order to shorten the construction period, reduce construction costs, mostly with concrete pump to speed up the construction progress. Then this time, choose a suitable concrete pump is very important! Concrete pump how to buy can not afford pit? These eight tips must understand the face of the current number of concrete pump truck manufacturers, as many products, I believe many people will suffer from the choice of phobia! In the end how to choose, we should pay attention to those aspects, and slowly see Oh, there are eight tips : Prior to purchase, users can learn about the quality of the company's pump trucks by referring to the certificate of appraisal, type test report, inspection report of special purpose vehicle strong-seeding items, motor vehicle catalog number, quality system certificate and so on. Concrete pump truck selection should be based on the object of concrete works, characteristics and requirements of the maximum transmission distance, concrete construction plans, concrete pump form and the specific conditions of line comprehensive consideration. Concrete pump performance varies with different models, in addition to taking into account the type of concrete pouring in addition to the type, it should also consider the type of construction and structure, construction technology requirements, site conditions and the environment. Usually the main performance parameters of concrete pump should be consistent with the construction requirements or slightly larger, if the capacity is too large, the utilization rate is too low, not only can not meet the requirements but also accelerate the loss of concrete pump truck. Concrete pump truck with flexibility, the higher the height of the boom, the greater the casting height and fabric radius, the stronger the construction adaptability, on the construction should try to use high-boom concrete pump truck. 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. When the height of the boom exceeds 42m, the cost is greatly increased and is limited by the construction site space. Therefore, it is seldom used. The quantity of concrete pump used in construction traffic can be calculated according to the concrete pouring volume, the actual delivery volume of single machine and the construction operation time. For those one-time concrete pouring a lot of concrete pumping construction, in addition to the calculation to determine, there should be a certain amount of spare. In addition, with an annual output of 10 to 150,000 M3 concrete mixing plant, equipped with 2 to 3 concrete pump truck. Concrete pump truck product performance in the selection should adhere to a high starting point. If the choice of high value concrete pump truck, then the standard requirements of their products also need to be improved. 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. Concrete pump truck with full hydraulic technology, so to consider all the advanced hydraulic technology, hydraulic vision how the quality. Because of its power from the engine, so in addition to consider the engine performance and quality, but also consider the performance of the car chassis, bearing capacity and quality. Concrete pump operation control system with manual, wired and wireless control methods, easy and flexible wired control, wireless remote control can be long-distance operation, once the circuit fails, manual operation can be used.
