介绍了一种以简单实用、价格低廉和技术先进为主要目标,打破传统设计理念的新型旋转小车式桥式起重机,给出了主要技术参数,阐述了总体构造及各部件性能特点.该机采用通用和标准的运行和旋转机构,单卷筒、双吊钩与侧挂式小车起升机构,变频调速等诸多措施,把上下层小车巧妙地结合起来,实现了小车的结构紧凑,新颖美观,经济实用,旋转运行平稳,定位准确.双钩完全同步升降,可靠性高,具有较高的实用价值.%With the simple utility, low price and advanced technology as main targets, the paper introduces an overhead crane with new rotary trolley which breaks through traditional design concept, provides main technical parameters and describes overall structure and performance characteristics of its parts. With several technologies such as general and standard travelling and rotating mechanisms, single drum, double-hook, side hanging trolley hoisting mechanism, and frequency control, etc. , the trolleys in up and down layers can be flexibly combined, which allows the trolleys to be compact in structure, innovative, economical and useful, stable in rotary running, and correct in positioning. Both hooks can be synchronously lifted and fallen, with high reliability and practical value.
