Electric gourds are widely used in various industries such as manufacturing, mining, transportation, and construction. Safety brakes are one of the very important safety devices. In many scholars' books, it is clearly written that the electric gourd's promotion mechanism, the operating mechanism, and some rotary agencies must have a brake safety device, and the braking decline distance should be guaranteed to be guaranteed at VN/100 (VN is the rated word and starting down the bottom. Within speed), it is not greater than 200mm.

In order to control the non -slip failure of the electric gourd, it is often installed on the motor axis to install a safety braker; for electric gourds with dangerous items or melting metals, in order to prevent the shaft, motor brake failure or the reduction of the reducer damage, bring it. The danger of coming should also be installed on the rolling tube shaft and a safe brake. The safety performance of electric gourds with wireless items or melting metals is particularly important, because once an accident occurs, it is a major event, which will directly hurt human life and property security.

Therefore, it is particularly important to study a safety brake machine on electric gourds used to hang dangerous items or melt metals.
