Lifting type of experiment and model (type) of the concept and its specific use

To clarify the issue of lifting type of experiment, just above explanation is not enough, the foundation of the problem is to clarify what is the type of experiment clearly? What type of experiment should I do? About the first question, after a research,jib crane I think that type of experiment is equivalent new product before it is mass production type of recognition, more precisely, a new product should be on the recognition of new models; Well, what is the model significance does it have? It should be said, the most basic models with lifting force layout pieces on top, and the choice of the primary data related to the primary organization and selection (include electrical system) equipment related, that is, only the elements of change, from the The models can be heavy machinery that has changed; establish if these ideas, then the type of experiment they should do according to models. So, models and how to show it? It should be said, one model can be used to indicate a type. The next question is what type of experiment is in accordance with category (type) to do it, still should follow models (type) to do it? Imagine,bridge crane if you do not follow models (type) do but follow types (ie type) to do, whether you can reach the type of experiment intentions? I think, you can not, reason: First, in the same category (type) in the presence of a variety of models (types), during which one model (type) after a type of experiment does not prove that another model (type) it must can pass type of experiment, but can not prove that during one model (type) after a type of experiment to explain the whole of this category (type) will be able to pass model experiments, the truth about the models from above (type) sense can be prove; Second, the State Council "special equipment catalog" (National Quality pot [2004] No. 31) in the category (type) layer of the primary lifting machinery in accordance with the primary distinguishing elements such as layout, you can not go down models (type ) on the distinction, otherwise too many levels, coupled with practical tasks, showing a new product is a new model, it will happen a new type, if the type is fixed, showing how to do new types? For encouraging the development of new products, the type can not be fixed, it should be rolled out and set up under abnormal conditions. According to the above thinking, AQSIQ pot in the national quality inspection [2003] No. 305 document type is given a meaning and rules of lifting type of experiment with the product type specifications as the basic unit; increasingly clear after the order type The significance in the type of experiment took him Conditions expressed as: type is the primary layout, the primary force layout data and vital pieces of the same process, the primary organization fit Series models equipped with a pleading, code from the product categories (type),hoist crane the layout mode, the primary component parameters, and use letters, numbers or a combination thereof indicate. Since then, basically clear expression of the type and its methods. For specific product type experiments, specific pilot projects, content and pleading, the paper does not open narrative.
