Lifting type experiment specification methods and ideas expressed in

 In theory, the mathematical specification is portrayed things big and small. Let's say lifting ordinary norms of ordinary means of lifting the primary technical parameters, there are many data components, such as the extra weight from the extra lifting moment, span, undulating, height, lifting speed, task level, etc. and so on. In lifting machinery production promised (inclusive type of experiment filed) and type of experiments relating normative documents and technical specifications Speaking of safety norms concept strange strange local intrinsic, common in the experimental project comes to be a broad sense, But in the production promised certificate (or filed notices) expressly refers to the norms of lifting the main parameters. Such as: overhead crane and  bridge gantry crane  main hook from the weight of the extra or additional tower crane lifting torque and so on. Expressed in the certificate was intended to simplify the drop type of experiment and forensics unit responsible, to prevent parameter changes slightly type experiments will be carried out and additional items forensics. So, how in the certificate indicates that regulate it? Especially showing double trolley, three car, or more cars, there are not high, ranging from the amount of the main hook condition how to do so? Under normal circumstances, marked a main hook up the extra weight on it, if showing the multi-car and other complex conditions, difficult to accurately express real clear,overhead gantry crane with promise certificate or filed notices on common parameters are not explained, this conditions can mark multiple hook derived by adding extra weight from the total weight of the largest since the additional, specific specific parameters in the type test report and be given clear instructions.

    These are special equipment existing regulations, norms, norms for the foundation of the Chinese  overhead bridge crane  type of experiment specific approach and type of experiment in the production of promise (inclusive type of experiment filed), making use of supervision and inspection carried out in a systematic introductions , discussion, thinking, represent only a small I know and understand, for learning to see, but also expect to send more in the future revision of the specification lifting, linking the actual situation and the existing regulations, standards, norms, in theory, the theory on the type of problem lifting to be completely clear, perfect crane type test criteria together in promoting the legalization of lifting machinery, guidelines, standardized and scientific, standardized process
