进行起重机轻量化后的外部效益分析是进一步促进轻量化起重机技术发展和推广应用的关键。在设计方法和评价参数两方面总结轻量化起重机特征的基础上,提出了一种起重机轻量化的评价方法,分析了轻量化桥式起重机外形尺寸、载荷、功率等因素对厂房净空高度、吊装面积、构件结构及耗电量的影响,介绍了3种用于厂房设计的起重机轮压优化设计方法,可节省厂房围护结构、柱和基础等构件的建筑成本和运营成本,带来百万级别的经济效益。
The analysis of the external benefit after the light weight of the crane is the key to further promote the development and popularization and application of the lightweight crane technology. On the basis of summarizing the characteristics of light weight crane from two aspects of design method and evaluation parameters, this paper presents a method to evaluate the weight of the crane, analyzes the influence of the dimensions, load and power of the light weight crane on the clearance height, lifting area , Component structure and power consumption, three kinds of crane wheel pressure optimization design methods for plant design are introduced, which can save the construction cost and operating cost of the building envelope, column and foundation and bring about 1 million levels The economic benefits.
