Concrete machinery produce different energy and productivity

Because concrete machinery, even if the same company in the same model, the same specifications of the product, just pumping concrete cylinder piston installation differences, it will make running resistance and productivity changes, will produce different energy and productivity, Precast concrete plant common sense, not to mention the various enterprises of different product positioning is not, as in the choice of parameters, the size of the pumping pressure distribution, configuration varies, cost is not the same, some specializing in long arm, some specializing in high- lift distance, some specializing in high-performance, some specializing in high reliability, how more than a few products only in the models, specifications of the choice of the enterprise is difficult to unity, why must we go to the strengths of their products than other people's so-called "short board" mean? So to be truly scientific and rational, there must be a professional appraisal team, concrete mixer machine on the content of the contest when possible. Of course, within the enterprise through pilot testing to compare the advantages and disadvantages of each enterprise products to improve their level is possible, normal. However, in a test of public occasions business model in the world market is also extremely rare. I hope the industry exclusive commercial activities organized similar events do not happen again.
