The intelligent crane controller is specially designed according to the speed regulating characteristics of a crane, and its intelligent frequency control module makes use of a thyristor (SCR) to control rotor resistance and motor rotation (positive and negative), thus realizing contactless speed regulation thoroughly. In this way, AC contactor won’t get damaged any more.
1. Frequency conversion technology for high efficiency and convenient speed regulation
2. High-dynamic torque control
3. Vibration abatement during low-speed operation
