Solution: When variable frequency speed control is adopted for the lifter, it is recommended that a special-purpose motor for variable frequency be used. CHV190 frequency inverter provides close-loop vector control way for hoisting mechanism, which ensures the hoisting mechanism does not slip at low speed and full load, and it starts and brakes smoothly. For electric brake, it is recommended that commonly used resistor energy consumption brake way be used.


  1. It is highly safe, reliable contracting brake and contact control procedures ensure lifter to operate safely and reliably.
  2. It is much more comfortable than a traditional non-speed-change lifter, and its debugging is simple and flexible.
  3. It is highly integrated, and special function for the lifter can be realized without using PLC.
