There is a saying that there is a working system during the operation of electric hoists. The working brake of electric hoists is usually intermediate JC25% and heavy JC40%. Many people are puzzled by this, but what does this value represent? Next, Guanhang will give you a scientific introduction to the working system of electric hoists.

Firstly, we need to know that the power of the motor is calibrated according to the JC value. According to the heating conditions, the allowable power output of the motor varies when operating under different JC values. If the JC value of the institution is high, the allowable power of the motor should be reduced, otherwise it can be increased. The standard JC value and its corresponding job category are usually divided as follows: light level: JC15%, medium level: JC25%, heavy level: JC40%, and extra heavy level: JC60%.

JC refers to the duration of power on, also known as the operating time rate of the institution. The duration of power on is the ratio of the operating time of the mechanism to the total time in a working cycle, i.e. JC=operating time/(operating time+stopping time) x 100%. When the lifting capacity of the electric hoist in the intermediate work system is reduced by 30%, it is equivalent to the electric hoist in the heavy work system JC40%. JC40% electric hoists with a heavy-duty working system are used in situations where the workload is heavy and the load is often at the rated value or requires a high safety factor.
