What are the technical standards for bridge cranes?

2019-09-11
The optimal design of the bridge crane is a multi-objective decision-making optimization problem involving many factors related to electromechanical design, manufacturing process, energy consumption, safety and environmental protection, etc. The overall requirement is to reach the economy. The overall optimal goal of benefit, environmental benefit and social benefit.

Quantitative analysis can be used for factors that affect technicality, while some factors that reflect processability, environmental protection, and economics cannot be or are not easily represented by numerical values. Qualitative analysis is required. For a single universal bridge crane, the equipment's own weight, profile size, limit size, speed regulation performance, manufacturing and installation processability (including production to commissioning cycle length) are indicators for assessing the design level. However, in addition to the above indicators, the series design should also evaluate such factors as: the standardization coefficient (mainly refers to the degree of generalization), and the coverage of the series of product parameters to meet the conventional demand (mainly refers to the degree to which the product parameters meet the conventional requirements, and also refers to the series design. Adaptation to the convenience of non-standard changes), derivable (referring to the convenience of extension and modification of basic products to other derivative series) and other comprehensive indicators.

Some indicators cannot achieve direct quantitative assessment, and need to be given by expert scoring. Therefore, the assessment indicators have a certain degree of relative accuracy and relative inaccuracy (fuzziness) related to human factors.
