关于冶金桥式起重机副钩的超载问题及解决方案

摘要

Based on the experimental results, calculation and demonstration, decided to use the crane hook of rated capacity from 5 to 8 tons. the Deputy roll lift weight increased by 60% than the original design after the transformation. According to the transformation of technical requirements, According to the structure and mechanism of crane the relevant part of the design, calculation, so that the original QDY32/5 t-25.5-A7 crane can meet the needs of production and in line with national standards.%根据实验结果并通过计算、论证，决定将该起重机副钩的额定起重量由原来的5t提高到8t，改造后的副卷扬起重量比原设计增加了60％。根据改造技术要求，经对该起重机结构和机构相关部分的改造设计、核算，使原QDY32／5tt-25．5-A7起重机能满足生产需要并符合国家标准．
