The main problems in the electric controlling part of the traditional sinking hoist are introduced,a frequency conversion adjusting speed controlling system is designed based on the load characteristic and behavior of the sinking hoist,and the application of ACS800-01 frequency converters in the system is emphatically analyzed.

In shaft construction,many sinking hoists were used to hang or bring to the stretch equipment like Hang dish,and template.

This paper introduces the work principle of four-quadrant operating high-pressure frequency converter,and its application in coal mine auxiliary shaft winch innovation system.
