Comparison of power consumption between variable frequency electric hoist and ordinary electric hoist

The frequency conversion electric hoist performs the lifting control operation of the object by adjusting the different frequency of the lifting object weight. The ordinary type of electric hoist generally refers to the lifting of the object at a fixed frequency. It is only from the power consumption level. It is the variable frequency electric hoist that saves more power, while the fixed frequency electric hoist consumes more electricity. Below we will compare the specific power consumption by the size of the object.

Power consumption of variable frequency electric hoist:

Power consumption/h     Cargo load

850W                     10T

750W                     8T

550W                     5T

Most of the common types of electric hoist are around 850W power, regardless of the weight of the lifted goods, it is a fixed consumption frequency.

In short, when the weight of the object we lifted by the electric hoist changes greatly, the frequency conversion is definitely more energy-saving, but the weight of the goods we lift is relatively large, and the price of ordinary electric hoists is cheaper. The electric hoist is more "sweet", and another point is that the heavier the weight, the smaller the difference in power consumption between the frequency conversion and the ordinary electric hoist
