Which type of Crane (Contactor Logic/ Drive Operated) you was Worked & What was Challenging Failures?

Question

Accepted Answer

I have worked with both types of cranes - contactor logic and drive operated. The challenging failures varied.

I have worked with contactor logic cranes in a steel plant where the main challenge was the wear and tear of the contactors due to the high current and frequent switching.
In a drive operated crane, the main challenge was the programming and tuning of the variable frequency drives to ensure smooth and precise movements.
I have also encountered failures in the control circuitry of both types of cranes, which required troubleshooting and replacement of faulty components.
Overall, both types of cranes have their own advantages and challenges, and the choice depends on the specific application and requirements.
