Most people think of chain type electric hoists with variable frequency electric hoists. Hebei Fanggong will introduce a steel wire rope variable frequency electric hoist and how it achieves variable frequency.

The wire rope electric hoist uses a frequency converter to change the frequency of the power supply, thereby controlling the speed of the motor and achieving frequency conversion.

The advantages of variable frequency electric hoists are mainly reflected in the following aspects:

1. Can set the lifting speed of the hoist according to requirements, and can set the lifting speed between 1/10 of the rated speed and the rated speed to select the most suitable operating speed.

2. Due to its smooth running performance, the electric hoist can reduce the impact during startup and shutdown, making it particularly suitable for installation of precision molds and other work environments where vibration is not allowed.

3. It can improve the working rate under idle conditions, set the lifting speed between the rated speed and 15 times the rated speed, and increase the operating speed under no-load conditions to improve work efficiency.

4. Variable frequency electric hoist can conveniently set the running speed of the small car

5. The frequency converter can be used to control the running motor, which can conveniently operate the motor at a micro speed, improve the accuracy of running positioning, and also perform jog operations.
