Solution for Frequency Inverters in Tower Crane Lifting Mechanisms

The lifting mechanism is the most important driving mechanism in tower cranestraditional speed regulation control methods require low-speed at heavy load, high-speed at light loada wide speed regulating range.
There are three principles for the speed regulation control method of the lifting mechanism: stabilitylow impact, efficientreliable according to local needs,easy to maintain.

The advantage after using EURA series inverter,
1. Decrease the starting current of motor.
2. Decrease the voltage fluctuation.
3. Excellent energy-saving effect.
4. Decrease mechanical consumption.
5. Simple control methods.
