In crane systems by KÜHNEZUG, advanced frequency inverter technology is used. Frequency inverters can change the amplitude and frequency of a voltage. The converted voltage is used to drive the lifting or drive unit motors, allowing continuous control of hoisting and travel speeds. Depending on requirements, two speeds and arbitrary acceleration and deceleration times can also be preconfigured.
This technology is standard for all our crane and trolley drive units. The KÜHNEZUG frequency inverter control system is also optionally available for all hoists.
