摘要
起重机起升机构调速系统的性能是起重机能否稳定运行的关键 ,自激动力制动保证了起升机构下降时能以较低的速度稳定运行。本文介绍了起重机的起升机构自激动力制动的电气调速方法的工作原理 ,并对其工作过程及性能做了介绍 ,为用户的使用。
The function of variable speed system in a crane is the key of stability to the crane, the variable speed system of power braking with self-excitation provides a way to the hoisting mechanisms descend in the lower speed, his paper presents the operating principle of power braking with self-excitation in cranes, and how this system works is introduced, this provides a reference for customer to use and repair.
