The variable frequency electric hoist uses a frequency converter to change the power frequency I to control the speed of the motor. Frequency conversion electric hoist has the following characteristics

1, can reduce the shock when starting and stopping. Because the electric hoist has the performance of smooth running, it can reduce the shock when starting and stopping. It is especially suitable for working environment where vibration is not allowed.

2, the lifting speed can be set as required. The lifting speed can be set from 1-10 rated speed to rated speed to select the appropriate operating speed.

3, can improve work efficiency. Under no load, the lifting speed can be set between the rated speed and 1.5 times the rated speed, and the running speed under no load can be increased to improve work efficiency.

4, it is convenient to set the running speed of the trolley. The running motor can be controlled by the frequency converter through the frequency converter, which can conveniently make the running motor run at low speed, improve the accuracy of running positioning, and can also perform jog operation.
