Research of hydraulic slewing institution of tower crane

介绍了塔式起重机回转装置的工作特性要求,论述了冲击载荷在塔式起重机工作过程中的不利影响;为了提高塔式起重机回转机构的工作性能,降低塔式起重机工作时的载荷冲击,设计了一种新型的塔式起重机液压回转机构。新型回转机构结构简单可靠、工作平稳、工作效率高,并且可以提供低速大扭矩,能够实现恒功率变速,具有实际意义和工业利用价值。

This paper presented the working characteristic requirements of the revolving mechanism of tower crane, and discussed the adverse effects of the impact load. In order to improve the working performance and decrease the impact load of the tower crane, a new type of hydraulic revolving mechanism of tower crane has been developed. The new revolving mechanism is simple and reliable, working smooth and efficient; the mechanism also can provide low speed with high toque, and change the speed with constant power. The new design has the practical role and high industrial utility value.
